Ecological Risk Assessment
2015 Monitoring Activities for Lake Michigan Long-term Ecological Research
Overview and Objectives
CILER supports the Ecosystem Dynamics branch at NOAA-GLERL to continue its collection of long-term ecological data and conduct targeted fundamental research on ecosystem processes critical to understanding ecosystem structure and function for managing water quality, fisheries, and other ecosystem services in the Great Lakes. Towards this goal, NOAA-GLERL has developed a Long-Term Research (LTR) program that integrates a core set of long-term observations on biological, chemical, and physical variables, with short-term process-based studies for understanding ecosystem change. Such information is essential for the development of new concepts, models, and forecasting tools to explore impacts of various stressors on the ecosystem. This research will contribute to GLERL’s core mission by providing data and understanding for the development of models and forecasting capabilities, and the application of new sampling technologies. The proposed research activities are organized into two general projects: LTR observations and process-based studies. It is implicitly understood that all process studies are targeted to understand critical processes affecting Great-Lakes LTR sites or ecosystems. It is our ultimate goal to understand structure and function of Great Lakes food webs from viruses to fishes and work efficiently as team to be ready for Coordinated Science and Monitoring Initiative (CSMI) Year of Lake Michigan 2015, when we intend to take a major leadership role. The single most important stressor in the system remains dreissenid mussels, and our team recognizes that observation of the pelagic realm alone is no longer an option. Dreissenid mussels, because of their high filtration rates and high abundance in all depth zones of the lake, have decimated the spring phytoplankton bloom and have decreased the abundance of phytoplankton in the hypolimnion and deep chlorophyll layer during the stratified season. They have also reengineered the ecology of the entire food web by increasing water clarity and altering nutrient cycling. It is believed they have had a negative effect on the food web, which is putting the valuable sport fishery at risk and is exacerbating nuisance growths of algae in the nearshore. We believe it is possible that dreissenid populations may be poised for a correction or crash.
