Abundance, biomass, and density of benthic macroinvertebrates collected from R/V Lake Guardian in Lake Michigan, Great Lakes from 2015-07-20 to 2015-07-29 (NCEI Accession 0209222)

Raw data from the benthic macroinvertebrate lake wide surveys conducted in Lake Michigan in 2015. These basic benthic survey data provide the number of each taxon in each replicate sample (abundance), density, and biomass. Similar lake wide surveys were conducted to assess the status of benthic taxa beginning in 1994/1995 and repeated every five years through 2015.
