Setting: Lake Erie Ecosystem Today
• Lake Erie is the shallowest &
most productive of the GL
with the largest watershed
• Heavily impacted by agriculture
& industry
• Houses the world’s largest
freshwater fisheries
walleye, yellow perch
& smallmouth bass
• Harmful algal blooms, declining
habitats, E. coli, sedimentation &
invasive species are growing
concerns
• Our Lake Erie Center programs are
dedicated to developing &
implementing solutions
LEC Environmental Research
Developing Hands-on Solutions to key
environmental problems at the land-lake
ecosystem interface
Multidisciplinary cutting-edge
scientific and engineering tools:






DNA & acoustic tracking of fish stocks (NOAA, USEPA)
HAB monitoring (NOAA)
Lake sensor network (NSF, USFS, USDA)
eDNA to track invasive species (NOAA)
Bioremediation (USDA)
Artificial wetlands (USEPA GLRI)
Education & Outreach Programs:


New LEC Land-Lake Sensor Network
Lake Sensor
equipment funded
by NSF FSML
Builds off Dr. Jiquan
Chen’s land sensor
network

Sensor Network Station Designs
Route of the LEC VesselMounted Flux Tower
• Through the Microcystis
algal bloom at the
estuarine of the
Maumee River
• Through the
sedimentary flow south
of the Detroit River
• Measurements taken
near permanent
stations in the Western
basin (PermS1, PermS2)
Preliminary Data from Marshland (coastal wetland)
versus Cropland (agricultural field) Sites
• Marshland releases evident
methane during the day
• Cropland releases methane
during the day and uptakes
small amounts during the
night
• The orders of methane fluxes
are much smaller in the
cropland than in the
marshland
• (Data from LEES Lab, Dr.
Jiquan Chen)
