We are providing improved seafloor mapping data products for regions of the Florida Keys National Marine Sanctuary deeper than 20 meters. Along with the mapping products, we will create an ...

In recent years, the central basin of Lake Erie has experienced low-oxygen conditions, despite measures taken by surrounding states and provinces to reduce nutrient inputs. We studied the factors that ...

Toxic algal blooms pose a serious health risk and often disrupt valuable regional shellfisheries. Eating seafood tainted with algal toxins can sicken or even kill people. We are pioneering use ...

An extensive bloom of the brevetoxin-producing Karenia brevis occurred from 2017 to 2019 in Florida. The economic, environmental, and human health impacts were quite severe during this event. This regional ...

There are no subtidal benthic habitat maps of Kachemak Bay, Alaska, to support essential fish habitat and place-based management needs. In response, we are developing benthic habitat maps for the ...

Ciguatera fish poisoning is the most frequently reported non-bacterial illness associated with eating fish in the United States and the U. S. territorial islands. Ciguatera significantly impacts commercial and recreational ...

State managers must assess contamination at abandoned mines, sewage outfalls, harbors, and other sites. We are determining the physical and chemical properties of sediments; measuring the chemical contaminants in sediment, ...

Through this pilot project in the coastal waters of Southern California, we demonstrated the effectiveness of adding emerging technologies to harmful algal bloom monitoring programs that focus on toxic blooms ...

In the waters surrounding St. Thomas and St. John, U.S. Virgin Islands, we conducted an assessment of the causes and effects of lost fish traps. We evaluated fish mortality, trap ...

This project aims to determine harmful algal bloom species composition and cell densities in Alaskan waters, and to model toxin transfer pathways to zooplankton, shellfish, finfish, and marine mammals, and ...
