Invasive Carp

Adult bighead, silver, and hybrid carp are invavsive species of fish that spread quickly once they are established in a water body. These carp damage habitat and reduce water-quality for native fish. Invasive carp have been confirmed within the Wabash River basin for at least 15 years. Scientists and natural resource managers are extremely concerned about the carp migrating to the Great Lakes...

Ecological Monitoring

Scientists research biology, botany, microbiology, habitat, climate, water quality, and other fields to achieve a comprehensive view of ecosystems and their health. Ecosystems can be easily stressed by human activities, climate change, sediment, nutrients, contaminants, and many other variables. Ecosystem monitoring is critical to ecosystem health and answers important questions about the...

Algal Biomass Lab

The Ohio-Kentucky-Indiana Water Science Center Algal Biomass Laboratory processes samples for chlorophyll-a and nutrients.  The analytical data for chlorophyll-a and pheophytin provided by USGS [periphyton samples collected by the Indiana Department of Environmental Management (IDEM)] are used by IDEM for water quality assessment and nutrient management planning.
