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...
