SUMMARY:10/25/17: Hongsheng Bi
DESCRIPTION:Please join us for a Great Lakes Seminar Series presentation:\nTime: 1:30-2:30 pm EDT \nLocation: NOAA Great Lakes Environmental Research Laboratory\, Lake Superior Hall\nPresenter: Dr. Hongsheng Bi\, University of Maryland\nTitle: Seeing the invisible in coastal waters: imaging systems for ecological monitor and forecasts \nEvent Flyer \nWebinar Recording: https://www.youtube.com/watch?v=X2uhyvBcxCQ&list=PLKF8ou9yUPhMYpbpU53OWvYLsa3vQjNAY&index=3 \nAbstract: Imaging systems have been proven useful for marine ecology. However\, deploying them in shallow coastal waters are often hampered by complex dynamic processes which often lead to sub-ideal image quality\, highly variable contents and backgrounds. In the present study\, we deployed a shadowgraph imaging system (PlanktonScope) to understand the spatial and temporal dynamics of dominant plankton taxa and an adaptive resolution imaging sonar (ARIS) to quantify forage species and their habitat utilization in shallow water estuaries. Results from PlanktonsCope captured a full bloom cycle of Noctiluca sp. in Shenzhen Bay in 2016\, while the deployment of ARIS system in Chesapeake Bay in 2016 – 2017 yielded useful estimates of forage abundance and their habitat utilization. Our results highlight that imaging systems could be useful for ecological monitor and forecasts in coastal waters and provide better insights on the spatial and temporal dynamics of key species\, trophic interactions and habitat utilization. \nBio: Hongsheng Bi is a fisheries Oceanographer specializing in the fine scale spatial distributions of different marine organisms and their trophic interactions. Hongsheng deploys advanced optical imaging systems and high resolution sonar imaging systems to quantify the spatial distributions and overlap of plankton\, forage fish\, and jellyfish. He is particularly interested in understand jellyfish dynamics and their interactions with other trophic levels. He is currently funded by NSF to investigate jellyfish dynamics and their impact on the Bering Sea ecosystem structure by deploying towed zooplankton imaging system (PlanktonScope) and the adaptive resolution imaging sonar (ARIS) systems. Hongsheng also operates a time-resolved Tomographic Particle Image Velocimetry at the Chesapeake Biological Laboratory\, University of Maryland Center for Environmental Science. \nImportant Visitor Information\nAll in-person seminar attendees are required to receive a visitor badge from the front desk at the NOAA Great Lakes Environmental Research Laboratory facility. Seminar attendees need to present a valid U.S. photo ID or green card. If you are a Foreign National\, advance notification of at least 48 hours is needed so that security guidelines are followed. You will need to present your passport (a copy will NOT work). For questions regarding building access\, or assistance in obtaining Foreign National clearance\, please call 734-741-2393.
