NOAA Great Lakes Environmental Research Laboratory (GLERL) samples and studies the ecosystem of the lower food web of the Laurentian Great Lakes. This collection contains zooplankton biomass and density data at 15 stations during the open water season in Lake Michigan from 2010-2019. Note, no samples were collected in Lake Michigan in 2012, efforts were instead put towards Lake Huron for the Cooperative Science and Monitoring Initiative (CSMI) that year. Zooplankton density is given in the number of organisms per cubic meter and biomass is given in milligrams per cubic meter. File formats included in this data package are .csv and jpg.
