Description of Work USGS will conduct seasonal sampling of benthic invertebrates, zooplankton, prey fish, and their diets to complement the seasonal lower trophic level sampling by EPA. A point of emphasis is describing the vertical distribution of planktivores and their zooplankton prey, to fill a knowledge gap on these predator/prey interactions. These data will provide a more holistic understanding of how invasive-driven, food-web changes could be altering energy available to sport fishes in the Great Lakes and used to build bioenergetics models that can evaluate whether zooplankton dynamics are being driven by limited resources or excessive predation. Understanding the key drivers of zooplankton will provide...

Description of Work USGS will conduct monthly samples of benthic invertebrates, zooplankton, and water quality as well as seasonal sampling of fish and fish diets. This project supports lower trophic sampling in Lake Erie and understanding food webs. An emphasis will be collecting samples from a nearshore to offshore design.

Description of Work Jeorse Park Beach is located in East Chicago, Indiana, within the Grand Calumet River Area of Concern (AOC), which has been identified as having all 14 beneficial use designations impaired, including beach closings. Jeorse Park Beach has been identified as one of the most highly contaminated beaches in the nation, with annual beach closings due to bacterial contamination as high as 76% in 2010. Further, beach closings have steadily increased each year since beach monitoring was initiated in 2005 in response to the Beaches Environmental and Coastal Health (BEACH) Act. Beach closings represent an environmental, social, and economic burden, the alleviation of which require various remediation strategies...

Description of Work USGS scientists will support EPA's year of intensive sampling around the Great Lakes to complement and expand upon EPA and other partner entities work. In 2013, on Lake Ontario USGS will sample the food web from a nearshore (20 m) to offshore (100 m) gradient where seasonal sampling of primary producers, benthic invertebrates, zooplankton, prey fish, sport fish, and their diets will occur. We will work closely with state management agencies and stakeholder groups to ensure that ecosystem models that emerge from this work explore relevant future management scenarios. Scientists will analyze the diets of the six species of trout and salmon currently occurring in Lake Ontario. This predator diet...

Description of Work In 2011, the US EPA, USGS, and Canada’s DFO/EC continued the evolution of the strategy to conduct an “integrated’ (water quality to fish) spatially-consistent assessment for the entire lake in order to provide biomass estimates for each trophic level. A total of 54 sites were sampled during summer 2011. Water chemistry, nutrients, phytoplankton, zooplankton, benthic invertebrates, Mysis, and pelagic and benthic fish were collected at each site.
