Title: Nitrogen availability as a driver of HABs and toxins: the missing piece for modeling?
Event Flyer
Webinar Recording
About the presentation: External nutrient loading (along with temperature and precipitation) is the main driver of annual harmful algal blooms in Lake Erie. These blooms are dominated by the cyanobacteria Microcystis, which produces microcystin toxins, but toxicity and biomass are not always correlated and can vary from year to year and within a season. Microcystis is an excellent scavenger for ammonium and can outcompete other organisms for this preferred ammonium supply. Ammonium is therefore both taken up by cells and recycled rapidly in eutrophic systems, making it difficult to determine availability snapshot concentration measurements. Studies on ammonium turnover rates in the water column of Lake Erie, as well as supply from sediments, suggest that internal loading is a critical component of sustaining bloom biomass. Using ammonium recycling rates in mixed models also results in strong models for concentration of microcystins (R^2 =0.84 or better), suggesting that ammonium availability might be key for modeling and predicting bloom toxicity.
About the speaker: Dr. Silvia Newell is an Associate Professor of Aquatic Biogeochemistry at Wright State University in Dayton, OH. Her research focuses on nitrogen cycling in eutrophic systems around the globe, from the Great Lakes to Lake Okeechobee to Taihu, China. She was the co-chair of the HABs Collaborative from 2018-2020 and currently serves as the President of the Lake Erie Area Research Network. She is currently NSF-funded on projects in Lake Superior, Lake Erie, and the Maumee River. She is also part of the monitoring team assessing the H2Ohio wetlands.

Presenter: Michael McKay – Executive Director and Professor; Great Lakes Institute for Environmental Research; University of Windsor
Title: Life under ice: The rise and fall of Lake Erie’s winter algal bloom
Event Flyer
Webinar Recording
About the presentation: Ice cover presents a logistical obstacle to our full understanding of function of north temperate ecosystems. Reflecting this, ecosystem models frequently underestimate, or even neglect biological parameters associated with ice cover. Despite the perceived inhospitable environment imposed by cold temperatures and ice cover during winter in Lake Erie, work over the past decade has revealed numerous examples of high biological activity with abundant phytoplankton biomass dominated by psychrophilic, filamentous diatoms. The diatoms are physiologically robust and the diatom bloom persists through early spring, eventually contributing to carbon export in Lake Erie’s central basin. During mild winters, the bloom is reduced, likely due to light limitation coincident with deep wind-aided mixing. These surveys have demonstrated that diatom assemblages possess ice nucleating abilities, a characteristic promoting ice formation and which enables the winter diatoms to maintain a favorable position in the photic zone when the lake is ice covered. Our recent efforts have focused on mechanisms of bloom decline where chytrid parasites and other pathogens are implicated. Broadening the impact of this research has been a unique partnership with the U.S. Coast Guard promoting citizen science in support of winter data collection.
About the speaker: In 2019, Mike McKay joined the University of Windsor where he serves as the Executive Director of the Great Lakes Institute for Environmental Research and Professor in the School of the Environment. Mike received undergraduate- and graduate degrees in Biology from Queen’s University at Kingston and McGill University (Montréal), respectively. Upon completion of his doctoral work, he held postdoctoral fellowships at the University of Alaska Fairbanks and with the University of Delaware where he served concurrently at the Department of Energy’s Brookhaven National Laboratory on Long Island, NY. It was during this period that Mike became active in research on aquatic nutrient cycling through his involvement with the ecosystem-scale ocean iron fertilization projects being conducted by scientific personnel from Brookhaven at that time. Mike’s research expanded to include large lakes on his arrival to Bowling Green State University where he served on the faculty for over 21 years studying the biogeochemical cycling of nutrients, phytoplankton and bacterial community dynamics and more recently, winter limnology involving research coordination with icebreaking programs of Canadian- and U.S. Coast Guards.
Among Mike’s research honors, he was awarded an Alexander von Humboldt Foundation Research Fellowship in 2005 where he was resident at the Helmholtz Centre for Ocean Research Kiel (Germany) and in 2013, was named Visiting Scholar at the Large Lakes Observatory of the University of Minnesota. He is the author of over 95 peer-reviewed manuscripts, is a co-recipient of the 2019 John Martin award from ASLO and currently serves as an Associate Editor for the Journal of Great Lakes Research.

Title: Building the environmental science toolbox to address the complexity of exposures and effects of emerging contaminants
Event Flyer
Webinar Recording
About the presentation: As a human population we use and are exposed to hundreds of chemicals each day, many of which are ultimately emitted into aquatic and terrestrial systems where other organisms are in turn exposed to these same chemicals. Assessing the impact of these chemicals in the environment has been a complex problem. Chemical composition and concentration vary over time and space and contaminants often occur as mixtures and therefore are difficult to characterize. Assessing the risk from these exposures is equally complex as research has shown that chronic low-level exposures have impacts on biochemical pathways that were not normally considered when evaluating safety. In addition, any one compound may occur at a dose that is below a traditional threshold of harm, yet the timing of exposure or exposure to a combination of chemicals ultimately can cause an effect. New chemicals in the marketplace, such as nanomaterials or new pharmaceuticals, present new questions as to their biological interactions and how best to determine their potential environmental impact. Research over the last 20 years has transformed the toolbox available to the field of environmental science to determine the extent to which these emerging contaminants impact organisms in aquatic environments. This presentation will discuss the innovations being made, through for example genomic technologies and in vitro screening, that advance our understanding of the interaction of emerging contaminants and organisms across phyla. Linking these technologies to environmental studies further builds the toolbox that can be used to better determine the safety of new chemicals and their environmental impact across organisms and ecosystems.
About the speaker: Rebecca D. Klaper is the Vice Dean and a Professor at the School of Freshwater Sciences, University of Wisconsin-Milwaukee. Professor Klaper studies the potential impact of emerging contaminants, such as nanoparticles and pharmaceuticals on aquatic life and how we may design these chemicals to have the least environmental impact. In addition, she has examined the transport of these chemicals through the wastewater treatment systems and into the environment and how different treatment technologies may remove them from the waste stream. Her research links the impact of these chemicals on the health of aquatic species to that of human health. She uses genomic technologies to determine how these chemical stressors may impact organisms and how the biochemical response may dictate sensitivity or resistance to stressors. As Director of the Great Lakes Genomics Center she seeks to support other researchers that are using genomic technologies for environmental research. Prof. Klaper has received a Fulbright Scholarship (U.K., 2017-2018) and a AAAS-Science and Technology Policy Fellowship. She has served as an invited scientific expert to both the U.S. National Nanotechnology Initiative and the international Organization for Economic and Cooperative Development panel on nanotechnology, the Alliance for the Great Lakes and the International Joint Commission regarding the potential impacts of nanomaterials, pharmaceuticals and personal care products and other emerging contaminants. She has served on the National Academies Panel on the Environmental Impact of Currently Marketed Sunscreens and Potential Human Impacts of Changes in Sunscreen Usage and another to Develop a Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials as well as the U.S. EPA Board of Scientific Counselors committee on Chemical Safety and Sustainability. Prof. Klaper received her Ph.D. in Ecology from the Institute of Ecology, University of Georgia.

Title: Self-Driving Water Systems
Seminar Flyer
Webinar Recording
About the presentation: In the era of digital assistants, autonomous cars, and smart toasters, should we embed the same level of intelligence into water systems? The answer is not clear cut, largely because the conversation is still obfuscated by buzzwords and hype. This talk will attempt to demystify and make accessible the building blocks of autonomous water systems. We’ll explore promising real-world examples of smart watersheds and “self-driving” urban drainage systems. Autonomous watersheds have the potential to vastly shrink the size of infrastructure needed to manage runoff pollution and flooding. We will give examples of promising smart water test beds, while also describing how to find useful data in unexpected places. As with any new tech, there are inherent risk to adoption. When compared to doing business as usual, however, the time appears better than ever to embrace new technologies for water management.
About the speaker: Branko Kerkez is the Arthur F. Thurnau Associate Professor of Civil and Environmental Engineering at the University of Michigan. His research interests include water, data, and sensors. His group is working to enable smart water systems, which autonomously adapt themselves to changing conditions using real-time data and controls. His research projects have spanned wireless sensing of large mountain basis, real-time flood forecasting, robotics, and real-time control algorithms for water systems. He is the founder of Open-Storm.org, an open-source consortium dedicated to freely sharing hardware, software, and case studies on smart water systems. He received his M.S. and Ph.D. in Civil and Environmental Engineering, and an M.S. in Electrical Engineering and Computer Science, all from UC Berkeley. He is a recipient of the National Science Foundation’s CAREER award and was recognized by National Academy of Engineering as a Gilbreth Lecturer.

Title: The Harmful Algal Bloom Assessment of Lake Okeechobee (HALO): Innovative monitoring technologies providing multidisciplinary insights into HAB dynamics and internal nutrient loading
Event Flyer
Webinar Recording
About the presentation: Annual blooms of Microcystis aeruginosa on Lake Okeechobee have increased in intensity over the last few decades, drastically affecting lake water quality and ecology as well as the health of surrounding coastal water bodies receiving lake inflows. As part of the State of Florida Harmful Algal Bloom (HAB) Innovative Technologies program, our team employed a comprehensive suite of innovative monitoring technologies alongside more conventional techniques over CY 2021to unravel HAB ecological, optical, and biogeochemical dynamics. Some techniques to be highlighted included remote sensing (satellite and a long-duration fixed-location i.e. Seaprism), in situ holography (AUTOHOLO), acoustic sensing (AZFP), an Autonomous Surface Vehicle, and fixed-location water quality sensors (LOBOs). This presentation will focus, however, on novel findings related to sediment biogeochemistry and internal nutrient loading. We combined routine sediment sampling and analyses with deployments of a novel benthic lander for in situ nutrient and toxin flux monitoring. To better understand the controls of sediment nutrient generation and release, we obtained voltammetric (electrochemical) measurements of the sediment respiratory environment (aerobic and anaerobic respiration). Findings suggest that both nitrogen and phosphorous speciation and solubility may be coupled to iron cycling via mineral associations and iron-catalyzed transformations, and that diffusive vs. resuspension fluxes play disparate roles with respect to nitrogen vs. phosphorous benthic fluxes. Overall, these dependencies may regulate both the intensity and timing of HABs over hourly to decadal timescales, with important implications for both passive and active mitigation strategies.
About the speaker: Dr. Beckler is an Assistant Research Professor at Florida Atlantic University, with a joint appointment with the Harbor Branch Oceanographic Institute, the Institute of Sensing and Embedded Network and Systems Engineering (I-SENSE), and the Chemistry Department. As the PI of the Geochemistry and Geochemical Sensing Lab, his group’s research centers around unraveling sediment biogeochemical processes in near-surface sediments and connections to ecosystem health. The lab develops and commercializes innovative technologies for monitoring sediment geochemistry (microbial respiration pathways/redox/nutrients) and exchanges with the water column (benthic fluxes). Current projects include monitoring Lake Okeechobee harmful algae blooms (FL DEP, EPA), the fluxes of carbon, iron, and CDOM from continental margin areas (NASA), and the exploration of submarine sink “blue holes” offshore in the Gulf of Mexico (NOAA).

Please join us for a Virtual Great Lakes Seminar Series presentation:
Time: 2:00-3:00 pm EST
Location: Insight into the past and present cyanobacterial blooms in Lake Superior
Presenter: Cody Sheik – Assistant Professor, Swenson College of Science and Engineering, University of Minnesota-Duluth
Event Flyer
Webinar Registration: https://register.gotowebinar.com/register/2538719994808348432
About the presentation: Cyanobacteria are extraordinary chemists that are integral to all surficial water ecosystems. As primary producers, they provide carbon and oxygen that drives heterotrophic productivity. Furthermore, the ability of some cyanobacterial species to fix nitrogen gives these groups a multifaceted ecosystem role. However, cyanobacterial overgrowth, e.g., cyanobacterial blooms, is increasing in intensity, duration, and severity in nearly all freshwater ecosystems. While the lower Laurentian Great Lakes (Lake Erie and Ontario) are prone to toxin-producing cHABs, Lake Superior, until recently, has not seen regular cHAB occurrences. The recent uptick in cyanobacterial blooms is unsettling and may be a harbinger of the changing chemical and physical characteristics of the lake. In my presentation I will talk about the changing nitrogen landscape of Lake Superior and focus on the presence of nitrogen fixing cyanobacterial blooms observed in Lake Superior.
About the speaker: Dr. Sheik received his B.S. in Zoology (2004) and PhD in Microbial Ecology (2011) from the University of Oklahoma. After graduation, he completed a postdoctoral position at the University of Michigan before coming to UMD in 2015. Dr. Sheik is a geomicrobiologist whose work in aquatic systems is at the intersection of three fields: microbiology, ecology, and geochemistry/geology. His lab currently investigates the microbiology of the deep subsurface, sediments, surface waters, and harmful algal blooms. His research seeks to understand how microorganisms mediate biogeochemical cycles, with emphasis on carbon, nitrogen, and sulfur in these disparate ecosystems.

Title: Interdisciplinary Perspectives on Equitable Urban Climate Change Adaptation in the Great Lakes
Event Flyer
Webinar Recording
About the presentation: Planning for climate change is critical for cities in the Great Lakes region. Preparing for changes in urban flooding frequency and severity is particularly important as precipitation during heavy rain events has increased, stormwater infrastructure is aging, and flood risk is distributed unevenly across and within communities. These adaptations require strong scientific foundations as well as political will, planning capacity, and community-driven decision making. In this talk I will discuss completed and ongoing research that aims to support equitable urban adaptation in the Great Lakes and improve our understanding of opportunities and challenges in this space.
About the speaker: Sara Hughes is an Associate Professor of Environmental Policy and Planning in the School for Environment and Sustainability at the University of Michigan and Associate Director of the Cooperative Institute for Great Lakes Research. Her research focuses on environmental policy agendas, policy analysis, and governance processes, focusing on decisions about water resources and climate change. Current projects examine the political and institutional dimensions of equitable access to safe and affordable drinking water in the U.S.; the role of municipal finances in drinking water management and investments; and urban climate change governance, including equitable approaches to building urban climate resilience. Information about current projects can also be found on the Water and Climate Policy Lab’s webpage: www.waterclimatepolicy.org.

Time: 11:00-12:00 pm EDT
Location: NOAA Great Lakes Environmental Research Laboratory, Lake Superior Hall and Virtual
Presenter: Andrew Ault – Associate Professor of Chemistry, University of Michigan
Title: Flying Slime: Lakes, Aerosols, and Harmful Algal Blooms

Event flyer
Webinar Recording
About the presentation: Aerosol production from wave breaking is one of the most abundant sources of aerosol globally, but emissions from freshwater lakes (lake spray aerosol, LSA) are poorly understood in comparison to sea spray aerosol (SSA). For calcareous lakes, such as the Laurentian Great Lakes, calcium carbonate is the abundant inorganic species, which can be aerosolized within LSA and undergo heterogeneous reactions similar to sodium chloride in SSA. In addition, harmful algal blooms (HABs) can lead to aerosolization of toxins like microcystins, which has the potential to lead to exposures to local populations. Given their small size and chemical complexity there is a significant analytical challenge when measuring these environmental contaminants. Herein, the chemical and physical properties of LSA from pristine freshwater and HABS are discussed., including measurements of particles along the coasts of the Great Lakes, inland, and aloft at cloud heights from flight measurements using a suite of microscopy, spectroscopy, and mass spectrometry measurements. As LSA can be generated and act as cloud condensation nuclei (CCN) or eject toxic materials from HABs, an improved understanding of LSA emission and physicochemical properties is needed to determine the impacts on meteorology, climate, and health in the Great Lakes and many other regions.
About the speaker: Andrew Ault received his B.A. from Carleton College where he first got involved with oceanic research during a SEA semester program measuring dissolved oxygen and chlorophyll on a sail bot traveling from Hawaii to Alaska. He received his Ph.D. in chemistry from the University of California San Diego where he studied individual particles emitted and transported in the atmosphere with real-time, single particle mass spectrometry under the guidance of Prof. Kim Prather (USCD/SIO). As a postdoc at the University of Iowa he worked with the Center for Aerosol Impacts on Chemistry of the Environment (CAICE) an NSF Center for Chemical Innovation focused on aerosol emission from marine source, blooms, and chemical reactions. In his independent career as a professor at Michigan starting in 2013, he has studied aerosol emissions from the Great Lakes and inland lakes and their reactions in the atmosphere. Recently, his group has focused on aerosolization from cyanobacterial harmful algal blooms (cHABs) and the potential for emissions of toxins. His group has identified significant concentrations of toxins in aerosols, different toxins and peptides.

Title: Bottom Roughness of Freshwater Ice: Impacts on Remote Sensing Observations, and Implications for Underwater Oil Releases

Event Flyer
Webinar Registration: Link
About the presentation: The ice underside in freshwater lakes of various sizes has been observed to be appreciably rough as a function of flow oscillations and pressure ridging in large open lakes, and variability in snow depth modifying the conductive heat flux (i.e. freezing rates) of the lake. In the case of an underwater oil pipeline rupture occurring in the winter, consolidated ice cover serves to both retain buoyant oil and mask the location of the oil to clean-up crews. The storage capacity of freshwater ice is a function of the roughness of the ice-water interface, the magnitude and correlation length of which varies dependent on the weather from year to year. This presentation focuses on preliminary investigations in the Straits of Mackinac which indicates that ice bottom variability in a region with considerable oscillatory flow is 0.3 m3 per m2, similar to that of first year sea ice. Additionally, the implication of ice-bottom roughness also extend to studies with the aim to improve the understanding of microwave interactions with freshwater ice (observed with airborne and spaceborne platforms), which holds potential to detect the presence of under-ice oil.
About the speaker: Dr. Gunn is an Assistant Professor in the Department of Geography and Environmental Management at the University of Waterloo (Canada) and formerly in the Department of Geography at Michigan State University. His expertise lies in the remote observation and retrieval of freshwater ice systems in sub-Arctic and Arctic environments. His research applies emerging technologies including airborne/spaceborne synthetic aperture radar, high-performance cloud computing (e.g. Google Earth Engine), interferometry, polarimetric decomposition and thermodynamic modeling. During his time at MSU, Dr. Gunn investigated the variability of ice properties using ground penetrating radar in the Straits of Mackinac to understand the holding capacity of oil under freshwater ice in the event of a spill in the Great Lakes.

Title: Bridging Western and Indigenous knowledges through University-Indigenous Community research partnerships: Sharing guidance from the “Seasons of Research” Framework

Event Flyer
Webinar Recording
Links of Interest: Bridging Knowledge Systems – Sharing Resources; Bridging Knowledge Systems and Expertise for Understanding the Dynamics of a Contaminated Tribal Landscape System (TLS)
About the presentation: This seminar provides guidance on creating and navigating the pathway to equitable, inclusive research partnerships. What is considered to be ‘normal’ research is in the midst of transformation as participatory, community-engaged research is no longer the exception but the expectation. With the realization that a diversity of stakeholders, rights holders, and research sponsors require more than can be accomplished by the solo investigator, how might one engage in this work in a good way? In this talk, I begin by explaining the term ‘bridging’ as an adaptable/adoptable concept and practice between Western and Indigenous knowledge systems. Then, following a brief description of my research foundations in fish, risk, and health, I outline our current research landscape with/by/as the Anishinaabe Ojibwa. As an example, I emphasize one project in particular that relies on guidance provided by the “Seasons of Research” framework, created in partnership with the Keweenaw Bay Indian Community Lake Superior Band of Ojibwa. In this socio-ecological systems research project (NSF AWARD #2009258), we are examining tribal landscape system (TLS) dynamics impacted by anthropogenic toxic contamination and climate-related changes.

Event Flyer
Webinar Recording
About the presentation: There is an all too common misconception that environmental justice law is vague and toothless. In fact, environmental justice law is nearly ubiquitous and has been significantly altering environmental decision-making norms. This talk will address the ways that environmental justice law has already shaped and may in the future shape Great Lakes environmental protection and restoration. Specifically, the talk will define environmental justice law, summarize its history, and go through Great Lakes case studies that illustrate how this legal framework alters decision-making regarding pollution control, natural resources management, and energy regulation.
About the speaker: Oday Salim directs the Environmental Law & Sustainability Clinic at the University of Michigan Law School, where he also co-directs the Environmental Law & Policy Program and teaches the Environmental Justice seminar. In addition, he is an attorney for the National Wildlife Federation in its Great Lakes Regional Center and the chair of the American Bar Association’s Environmental Justice Committee. Professor Salim has taught courses on environmental justice, energy regulation, and mineral law. As an attorney, his most recent work has addressed water affordability, oil pipelines, Clean Water Act permitting, stormwater management, and the public trust doctrine.

Title: Plant community dynamics linked to ecosystem biogeochemistry in Great Lakes coastal wetlands: modeling for both basic understanding and management applications

Event Flyer
Webinar Recording
About the presentation: Linking plant community dynamics to ecosystem processes has long been a central theme in ecological modeling. In this seminar, Bill Currie will present the development and applications of the Mondrian model, which was designed to link across four levels of organization in coastal wetlands: individual plant physiology, plant population dynamics, plant community shifts including invasive species, and ecosystem biogeochemistry including C, N and P cycling. Mondrian is an individual-based model in which spatially-explicit plant competition for resources causes emergent population and community dynamics, which respond to wetland N and P inflows while also driving ecosystem N and P cycling including nutrient retention. At the same time it integrates the effects of dynamic water levels, hydroperiod, and water residence time on both plant survival and ecosystem biogeochemistry, including decomposition, C storage, nitrification and denitrification. It has been used to study clonal plant competition broadly from a basic-science perspective as well as the integrated effects of water level and nutrient inflows on the joint outcomes of wetland C budgets and the success or failure of plant invasions in Great Lakes coastal wetlands. The model has also been used in an adaptive management framework to simulate the outcomes of management practices including burning, mowing, and herbicide to control invasive cattails and Phragmites. The Mondrian model was designed to be highly flexible for use by different research groups for a range of research questions and is available open-source.
About the speaker: Bill Currie is a Professor and Associate Dean for Research and Engagement in SEAS. He is also Co-Director of the Schmidt AI in Science Postdoctoral Fellowship Program at the Michigan Institute for Data Science (MIDAS). Previously, he chaired the Provost’s Faculty Transition Team to plan the new School for Environment and Sustainability, which opened its doors in 2017. Currie is an elected Fellow of AAAS for his work in ecosystem simulation modeling, in which he models forests, human-dominated landscapes, wetlands and coastal ecosystems, biogeochemistry, and water quality. He collaborates with investigators across a range of fields from wildlife conservation to economics, civil engineering, and urban planning to understand human-environment systems. He is PI on the grant to launch the SEAS Sustainability Clinic in Detroit. Currie teaches sustainability using a variety of case studies drawn from the Great Lakes region.

Time: 12:00-1:00 pm EDT
Location: NOAA Great Lakes Environmental Research Laboratory, Lake Superior Hall and Virtual
Presenter: Silvia Newell, Director, Michigan Sea Grant and Professor, University of Michigan
Title: Assessing Nutrient Load Reductions in H2Ohio Constructed Wetlands: Case Studies from Brooks Park and the Burntwood-Langenkamp Wetlands

Event Flyer
Webinar Recording
About the presentation: Wetlands perform critical ecosystem services, including nutrient reduction, flood mitigation, and biodiversity habitat. More than 90% of wetlands in Ohio have been destroyed and most major water bodies in the state now experience annual harmful cyanobacterial blooms. The H2Ohio Initiative in part funds statewide wetland restoration to improve water quality through nutrient reduction. Dr. Newell is one of the H2Ohio Wetland Monitoring Program leads, monitoring water quality at newly constructed wetland or restored wetlands. This talk will focus on nutrient reductions at two wetlands: Brooks Park flowing into Buckeye Lake, a hypereutrophic lake experiencing annual harmful algal blooms. Brooks Park wetland was built at the junction of Murphy’s Run creek into Buckeye Lake, draining a very small watershed (1.2 sq. miles) and behaves as either a flow-through wetland or a coastal wetland depending on precipitation. Preliminary data from the first year of monitoring indicates that the wetland is a sink for total nitrogen (>3000 lbs/yr), but a small source of ammonium (~44 lbs/yr). However, the wetland is a very small source of total phosphorus (~42 lbs/yr), while a sink for soluble reactive phosphorus (~16 lbs/yr). The 90-acre Burntwood-Langenkamp Wetland Conservation Area is located at the confluence of Burntwood and Coldwater Creeks in Mercer County. This site is a former corn/soybean field in the Grand Lake Saint Marys watershed. Water enters the site from Burntwood Creek (BWC) through pump and overflow and then flows through a series of settling ponds and vegetated flats that extend for over a mile. BWC drains approximately 5,700 acres of watershed land and can hold approximately 20 million gallons of water. Total Nitrogen (TN) concentrations at the outflow are approximately 73% lower than the TN inflow concentrations, which average over 16.3 mg N/L for the year 2023. An approximate annual decrease thus far of ~55% in SRP concentration has been seen between the inflow and outflow with outflow concentrations averaging 0.044 mg P/L. Nutrient load reduction will likely vary as the wetlands mature, but data from the first year indicate that both wetlands are already performing a vital ecosystem service.
About the speaker: Silvia Santa Maria Newell is Michigan Sea Grant’s director, based in Ann Arbor at the University of Michigan. A nutrient biogeochemist and microbial ecologist, Silvia’s own research focuses on the effects of excess nutrients from fertilizer and wastewater on inland and coastal waters, particularly harmful algal blooms (HABs) in Lake Erie. Her current collaborative work in the Lake Erie watershed focuses on engaging stakeholders (farmers, managers, and policymakers) to develop realistic pathways for nutrient reduction. She has held many leadership positions, including serving as co-chair of the Great Lakes Commission HABs Collaboratory for two years and her current position as President of the Lake Erie Area Research Network.
In addition to serving as MISG director, Silvia also serves as a professor at the University of Michigan School for Environment and Sustainability.

Title: Observing, Characterizing, and Quantifying Wintertime Precipitation Processes: A 10 Year Retrospective from Marquette, Michigan

Event Flyer
Webinar Recording
About the presentation: Winter precipitation (rain and snowfall) has widespread impacts on communities through regional ecology, hydrological planning, and socioeconomic effects. In this presentation, I will feature important findings from winter weather regime-based studies leveraging precipitation observations from a long-term, ground-based instrument suite in the Northern Great Lakes region. Realistic estimates of rain and snowfall in weather forecasting and climate models are challenging due to uncertainties in cloud and precipitation parameterization schemes. Additionally, remote-sensing observations require assumptions about hydrometeor microphysical and radiative properties. High temporal resolution, multi-instrument observations of clouds and precipitation can help better constrain processes in models and refine retrieval assumptions, leading to more accurate quantification of accumulation. I will highlight the advantage of utilizing long-term observations to examine key physical and dynamical precipitation processes through the lens of regime partitioning. Precipitation regimes are determined using observations of macrophysical and microphysical properties, large-scale environmental conditions, and thermodynamic profile characteristics. Key findings demonstrate that regime-dependent characteristics of precipitation lead to distinct differences in frequency, intensity, and phase, microphysical properties, and overall accumulation. Additionally, I will demonstrate how winter precipitation regimes in the Northern Great Lakes region are tied to significant seasonal and subseasonal, synoptic, and thermodynamic conditions such as atmospheric blocking and anomalous moisture transport (atmospheric rivers).
About the speaker: Claire Pettersen is currently an Assistant Professor in the Department of Climate and Space Sciences and Engineering at the University of Michigan. Prior to joining the University of Michigan in 2022, Dr. Pettersen worked as an engineer and research scientist at the University of Wisconsin-Madison for more than 15 years. Dr. Pettersen’s research is focused on cold-season and cold-location precipitation (snow, mixed-phase, rain), as well as associated cloud, thermodynamic, and synoptic characteristics. Much of her research is focused on the mid- and high-latitude regions of the world where the climate is rapidly changing.

Title: Thirty-five years of progress on the Great Lakes: from no policy to global ballast water standards

Event Flyer
Webinar Recording
About the presentation: Expert opinion has placed invasive species as a top stressor of the Great Lakes. Up until the late 1980s, ballast water – the principal pathway (65% of invasions) for species introduction to the system – was unregulated. Invasions by zebra mussels and Eurasian ruffe focused attention of researchers and policy makers on the ballast water threat, resulting in a 1993 USCG policy mandating ballast water exchange (BWE) for vessels entering the system with filled ballast tanks. A retrospective analysis of reported invasions 13 years before and after implementation of the policy shows that new ballast-mediated invasions was virtually unchanged (16 vs 15 species, respectively). Further policy change in 2006 (Canada) and USA (2008) required even vessels with residual ballast water to ‘flush’ open-ocean water through tanks before entry, and coincided with a dramatic decline in new invasions (2 species) over the following 13-year period. This decline is best explained by policy change and not by alternative explanations (shipping volume, source pool depletion, search effort). The International Maritime Organization is presently implementing a new global policy (IMO D-2) based on abundance-based performance standards for different size classes of introduced organisms. The theory behind this policy is based on the well-established principle of ‘propagule pressure’, which defines risk based on the concentration of viable organisms discharged of a single species. However, IMO D-2 is based on ‘community propagule pressure’, a nebulous and unstudied concept, and it ignores the conflating influence of colonization pressure (ie. the number of species introduced). Here I will show that at the concentration of organisms relevant to IMO D-2, colonization pressure has a much greater influence on probability of invasion than ‘community propagule pressure’. I will also examine compliance with the new IMO D-2 standard for zooplankton, and suggest safeguards for the Great Lakes to ensure that vessels do not exceed permissible abundance discharge limits.
About the speaker: Hugh MacIsaac is a professor and Canada Research Chair in Aquatic Invasive Species at the Great Lakes Institute for Environmental Research, University of Windsor (Windsor ON). He also teaches and conducts research at Yunnan University in Kunming, China. Hugh served as director of the CAISN research networks addressing aquatic invasive species in Canada. He has authored over 250 peer-reviewed papers and was honored with the Rigler Award from the Society of Canadian Limnologists. Hugh earned his Ph.D. degree (long ago) from Dartmouth College studying zooplankton ecology. He is interested in a variety of issues pertaining to invasive species including analyses of pathways of introduction, risk assessment, genetic characterization and evolution of invasive species, and management. In his spare time, he and his wife Jaimie enjoy cycling.

Title: Applying New Technology at a Great (Lake) Scale: What are We Waiting for?

Event Flyer
Webinar Recording
About the presentation: Despite the ubiquity of modern electronics in our pockets, cars, and buildings, there’s still relatively few sensors deployed in the natural environment, including the watersheds, nearshore areas and open waters of the Great Lakes. Why is that? This seminar will examine a few case studies where the number of sensors has scaled quickly and where progress has stalled. Technological advancements have helped to increase sensor reliability and lower costs (both capital and operation), but catastrophic events are still the main catalyzing force driving rapid change in the region. Examples include the sinking of the Edmund Fitzgerald, large hurricanes, and more recently the Toledo Water Crisis. These events have been the nucleation point that has driven the deployment and ongoing operation of over 100 operational sensors on the Great Lakes. However, these investments pale in comparison to the rapid adoption of sensors in other public sectors including transportation (traffic), energy (smart grid), and even terrestrial weather. Government funding after each disaster helped rapidly advance new sensor networks, however, ongoing expansion and operation of similar sensors has fallen on a mix of federal, state, and local sources of funding. However, there are some exceptions including the use of technology within fisheries management, which is accelerating adoption of several low and high-tech sensor networks. A myriad of agencies and commercial companies all play a role in coordinating, funding, and maintaining sensors networks in these public spaces. Identification of mismatches between investments (either in the public or private sector) in monitoring and public health or shear economic value are easy targets for expansion. While deploying and maintaining sensors offshore is challenging, there’s many opportunities to grow watershed, shoreline, and mobile asset monitoring. Careful attention needs to be paid to the means of funding (public) or monetization (private), and how to incentivize, rather than mandate, the expansion of sensor networks that reduce risk (health or financial) and improve our understanding of the largest freshwater ecosystem on the planet.
About the speaker: Ed Verhamme is a Principal and Senior Engineer at LimnoTech and was recently named president of Freeboard Technology, a new water technology start-up he co-founded as a subsidiary of LimnoTech. Ed is well known for his work across the Great Lakes region and other key lakes in the United States to design, build, and maintain the next generation sensing network that supports hundreds of thousands of boaters, key water managers, and critical infrastructure owners. He holds a M.S. and B.S in Environmental Engineering from Michigan Technological University, where he first applied models and advanced sensors to study the depths of Lake Superior and has since studied portions of every Great Lakes. Drinking water treatment plants, coastal communities, and the research community rely on Ed’s expertise to monitor and model hazardous weather, toxic and harmful algal blooms, hypoxic waters, and critical shoreline and wetland habitats. He has also served as a principal investigator on several major federally funded research projects and has contributed to nearly twenty peer-reviewed journal articles and mentored a dozen master’s and PhD students. In 2021, Ed served as president of the International Association for Great Lakes Research and in 2023 received its highest service award, the Anderson-Everett Award. Ed works at LimnoTech’s office in Ann Arbor, Michigan.

Presenter: Jeffrey Freymueller, Professor, Endowed Chair for Geology of the Solid Earth, Michigan State University
Title: Geodetic Observations of Water Mass Changes in the Great Lakes Basin

Event Flyer
Webinar Recording
About the presentation: Changes in total water mass now can be measured by ground-based and space-based observations. As water moved around the planet, the entire Earth deforms as a result of the changing force exerted by the weight of the water, and we can measure these motions using precise GPS observations. The gravity changes due to the changing distribution of water can also be measured using data from the GRACE satellite mission. Because these observations provide estimates of the total water mass changes, we can combine them with measurements of surface water changes to infer changes in groundwater, which are otherwise hard to measure. Previous work showed that the 2012-2019 rise of Great Lakes water levels produced up to about 2 cm of ground subsidence, which we can observe in GPS data. To make accurate estimates of the water mass variations, we will need to fully understand noise and any biases, and carefully remove all signals that are not due to the water (for example, atmospheric pressure loading and glacial isostatic adjustment). We are about 1 year into a 5 year project to make these measurements and fuse them with groundwater modeling and other remote sensing data to develop a groundwater model for the Great Lakes Basin.
About the speaker: Freymueller is an internationally recognized leader in the field of geodesy, and utilizes satellites from the Global Positioning System (GPS) to make highly precise measurements of movement on Earth’s surface. In his far-reaching research activities, he has made discoveries in a wide range of topics including plate tectonics and plate boundary zones, faults dynamics, the continuing rebound of the Earth’s surface from the melting of ice-age glaciers, inflation and deflation of volcanoes, and interpreting how changing water and ice levels deform the Earth. He is particularly well-cited for his work on using GPS to understand the crustal deformation in China, related to the formation of the Himalayas and the Tibetan Plateau.
In addition to his research, Freymueller is the Director of the EarthScope National Office. EarthScope is a long-term, large-scale, NSF-funded program to study the structure and evolution of North America and associated hazards through the deployment of thousands of geophysical instruments throughout the country.
Freymueller also has served the scientific community as the US National Correspondent to the International Association of Geodesy and its representative to the International Union of Geodesy and Geophysics, has served terms as an Associate Editor for the Journal of Geophysical Research and Journal of Geodesy, and is currently Editor in Chief of the International Association of Geodesy Symposia Series.

Title: Climate, Chemistry and the Great Lakes: What Goes Up Must Come Down

Event Flyer
Webinar Recording
About the presentation: The Laurentian Great Lakes can influence regional climate and chemistry through a variety of mechanisms, and I’ll discuss these chemistry-climate interactions from the perspective of what goes up (e.g., water via evaporation, aerosols via lake spray) versus what comes down (e.g., aerosol deposition of nutrients, precipitation). From the climate perspective, we analyze the atmospheric moisture budget in the Great Lakes region using reanalyses and future climate model data to develop a process-level understanding of the precipitation seasonality. We identify the lakes not only as a source of moisture, but also in generating localized moisture flux convergence/divergence patterns that affect the seasonality of the water cycle. Despite differences in historical simulations from the Coupled Model Intercomparison Project (CMIP6) data archive, common patterns of change are present in the future projections of the atmospheric water budget. Specifically, summer drying and winter/spring wetting by mid-century is consistent across models, indicating a shift in the precipitation seasonal cycle towards colder months, while evapotranspiration magnitudes revealed unambiguous increases throughout the year in all models. Overall, the atmospheric transport of moisture is the primary driver of future precipitation changes, with an amplification of the moisture flux convergence seasonal cycle in future climate model simulations. From the atmospheric chemistry perspective, I’ll discuss the role of the lakes as a source or sink for chemical constituents in the atmosphere. Emissions of lake spray aerosol (LSA) can be a regional source of aerosol, and including LSA in regional chemistry models increases aerosol pH in the Great Lakes region and enables the partitioning of nitrate to the aerosol phase. Overall, this suggests that LSA should be included in regional assessments of atmospheric chemistry and air quality. The deposition of atmospheric aerosols is a source of phosphorus to the Great Lakes region, and while this contribution is small compared to surface runoff, it has not been well-constrained. We quantify the phosphorus deposition to the Great Lakes using a combination of ground-based measurements and models across the region, and highlight uncertainties in this atmospheric source of phosphorus.

Webinar Recording
About the presentation: How do we pull together those with skills and talents steeped in disciplinary knowledge and inhabitant experience to interpret and respond appropriately to the radical uncertainties of rivers and lakes enacting climate change extremes? Based on her ethnography of flood control in urbanized Manitoban floodplains, Stephanie Kane identifies and recasts key aspects of traditional expert-inhabitant forecasting. She proposes touchstones for a place-based/planet-informed path forward that affectively and effectively grounds engineering, science and law in environmental and social justice.
About the speaker: Stephanie C. Kane is a cultural anthropologist and Emerit Professor of International Studies in the Hamilton Lugar School of Global and International Studies. Her earlier book on water and cities is entitled Where Rivers Meet the Sea: The Political Ecology of Water (2012, Temple). Her most recent book, Just One Rain Away: The Ethnography of River-city Flood Control (2022 McGill Queen’s) brings together diverse experimental fieldwork-based methods. Using geoscience and flood forecasting, Kane interprets the perspective of water and ice as earth-shaping riverine actors who encounter collective humans in the form of cities. By drawing on official post-disaster reports, novels, a play, personal experience narratives and an emergency press conference, Just One Rain Away writes humanity’s existential climate-changing moment into the peculiar place-based intersection of historical and geological time.

Event Flyer
Webinar Recording
About the presentation: Phytoplankton are key primary producers performing half of Earth’s carbon fixation, forming the base of aquatic food webs, driving major biogeochemical cycles and affecting water quality. Understanding how phytoplankton respond to changing environmental conditions, including global climate change, is critical for our ability to predict the fate and functioning of aquatic ecosystems. I will present examples of how we can use trait-based approaches to improve our mechanistic understanding of phytoplankton community reorganization under different conditions, including the occurrence and proliferation of harmful algal blooms.
About the speaker: Elena Litchman is an MSU Research Foundation Professor at Michigan State University. She studies the responses of aquatic ecosystems to changing environments, including anthropogenic global change, and the consequences of those changes for biodiversity, biogeochemical cycles, and ecosystem functioning. She focuses on microbial communities and conducts research in a wide range of systems, from lakes in the US and Siberia to the global ocean and experimental phytoplankton communities. She combines experiments, field studies and mathematical models to address ecological questions of fundamental and applied significance.

Title: The Maritime to Inland Transitions Towards ENvironments for Convection Initiation (MITTEN-CI) Field Campaign

Event Flyer
Webinar Recording
About the presentation:The evolution of the marine atmospheric boundary layer as it advects inland during the warm season plays a critical role in the initiation–or suppression–of convection in the Great Lakes coastal
environment. Gaining a deeper understanding of these transitions and their effects on convection is of significant importance, particularly given the large population in many coastal areas. To address this, the
National Science Foundation-funded Maritime to Inland Transitions Towards ENvironments for Convection Initiation (MITTEN-CI) campaign was conducted in July 2024, with the goal of developing an extensive dataset that could effectively characterize these transitions. Over-lake thermodynamic and kinematic profiles were observed by Uncrewed Aircraft Systems (UAS), while sampling of boundary layer spatial and temporal variability over land was observed by a 120 km long shore-perpendicular transect including six flux towers, two mobile mesonets, multiple radiosonde launch sites, a Doppler LiDAR, and two mobile Ka-band Doppler radars. This dataset enables hypothesis testing that will result in new knowledge of processes that support the development of instability maxima on the cool side of lake-breeze fronts (LBFs), the potential for diffuse LBFs to exist embedded within synoptic-scale onshore flow and influence CI, the prevalence of misovortices at intersections of horizontal convective rolls and the LBF, RKW theory’s relation to the vertical structure of the LBF, and the influence of entrainment on the thermodynamics and structure of the boundary layer and the LBF. This talk will provide an overview of the MITTEN-CI campaign, highlighting the unique data collected, with additional insights provided through analysis of relevant idealized simulations.
About the speaker: Jason Keeler is an Associate Professor of Meteorology and has been a faculty member of Central Michigan University’s Institute for Great Lakes Research since 2018. He joined the faculty at CMU following postdoctoral studies at the University of Nebraska-Lincoln, and graduate studies at the University of Illinois at Urbana-Champaign. His research blends aspects of boundary layer and mesoscale dynamics, with a focus on destabilization and evolution of convection, often applied to coastal areas. Jason and his collaborators explored these processes in summer 2024 through the NSF-funded MITTEN-CI field campaign (Maritime to Inland Transitions Towards ENvironments for Convection Initiation). In his spare time, Jason is an avid gardener, and enjoys traveling with his husband.

Please join us for a Great Lakes Seminar Series – subscribe!
Time: 11:00-12:00 pm EST
Location: NOAA Great Lakes Environmental Research Laboratory, Lake Superior Hall and Virtual
Presenter: Christiane Jablonowski, Professor of Climate and Space Sciences and Engineering
Title: Representing Lake-Atmosphere Interactions in NOAA’s Weather Prediction Models

Event Flyer
Webinar Recording
About the presentation: The talk provides an overview of various lake-atmosphere coupling approaches that are either currently employed or envisioned for NOAA’s suite of weather prediction models across a range of temporal and spatial scales. Special attention is paid to the representation of the Laurentian Great Lakes in the high-resolution, convection-allowing NOAA forecast models HRRR as well as the newly-developed Rapid Refresh Forecast System (RRFS). The latter is based on a configuration of NOAA’s Unified Forecast System (UFS). The lake surface conditions for temperature and ice are either represented via NOAA’s operational 3D FVCOM lake modeling framework with the embedded lake ice component CICE or represented via a simpler 1D modeling approach based on the CLM lake parameterization. The talk will compare these two lake modeling approaches, will survey the pros and cons of online and offline lake-atmosphere coupling ideas, and will shed light on the temporal coupling frequency. The ideas will be illustrated via selected case studies that focus on lake-effect snow events during the winter months. These lake-effect snow events downwind of the Great Lakes are especially sensitive to lake-atmosphere interactions and thereby serve as suitable exemplars.
About the speaker: Christiane Jablonowski is a Professor in the Department of Climate and Space Sciences and Engineering at the University of Michigan. She also worked at the National Center for Atmospheric Research (NCAR), NOAA’s Geophysical Fluid Dynamics Laboratory, and the European Centre for Medium-Range Weather Forecasts.

Time: 11:00 AM – 12:00 PM EDT
Location: NOAA Great Lakes Environmental Research Laboratory, Lake Superior Hall and Virtual
Presenter: David M. Lodge, Francis J. DiSalvo Director of Cornell University’s Cornell Atkinson Center for Sustainability
Title: The promises and perils of research in solving sustainability problems

Event Flyer
Webinar Recording
About the presentation: Researchers often assume that the value of research in solving problems is self-evident. Yet most research does not lead to solutions, even when the proposals that launched the research promised solutions. University and government researchers could address this longtime peril by including clear theories of change in project development, and co-creating and co-executing projects across disciplines and sectors. This would require alignment of funding and infrastructure to support such mission-driven research. In a rapidly changing government landscape, I will examine past examples of the role of research and technology development in driving change in policies, practices, and products. While I do not promise to resolve all the promises and perils, I will suggest some possible ways forward for solutions-oriented sustainability research in government and universities.
About the speaker: Dr. David M. Lodge is the Francis J. DiSalvo director of Cornell University’s Cornell Atkinson Center for Sustainability. He is an internationally recognized environmental scientist, with expertise in environmental risk assessment, freshwater and marine coastal ecology, ecosystem services, bioeconomics, and invasive species. His research has improved ecological forecasting to better inform environmental risk assessment, natural resource management, and policy development. Lodge is a leader in the development and application of environmental DNA (eDNA), a transformative technological tool for discovering unrecognized biodiversity, censusing aquatic biodiversity, and improving the management of imperiled, invasive, or harvested species. He is past president of the Ecological Society of America, and former senior science advisor in the US Department of State’s Office of Polar Affairs. On numerous occasions he has testified before the U.S. Congress, and served as an expert witness in federal court. He is faculty member in the Department of Ecology and Evolutionary Biology at Cornell
University.
