Summary
This dataset records Cladophora and associated benthic algae, collectively Cladophora community or submerged aquatic vegetation (SAV), biomass collected during the growing season of 2020 at stations located along the U.S. shoreline of Lakes Michigan, Huron, and Erie. It also records a variety of supporting data collected at Cladophora measurement stations. These supporting data include: - measurements of Secchi disk depth and water chemistry; - water column profiles of temperature, specific conductivity, turbidity, pH, phycocyanin, chlorophyll, and dissolved oxygen; - diver observations of SAV, dreissenid mussels, round goby abundance, and substrate properties; - measurements of dreissenid mussel abundance and size class distribution [...]

Similar data were collected at several of the same transects within four Great Lakes in 2018 and 2019 and are available at (2018) https://doi.org/10.5066/P9E570JS and (2019) https://doi.org/10.5066/P99O4QXB.

Purpose
The purpose of this data collection was to assess live Cladophora abundance in nearshore areas of the Great Lakes with suitable substrate and factors associated with Cladophora growth, including dreissenid mussels, phosphorus availability, and physical conditions. Sites were selected for this purpose, and supporting data were collected to aid in interpretation of Cladophora patterns.
