At the USGS Eastern Ecological Science Center (EESC), we strive to provide world-class science to inform natural resource decisions that preserve and enhance our quality of life.
EESC Cooperative Science with the Atlantic States Marine Fisheries Commission
EESC Cooperative Science with the Atlantic States Marine Fisheries Commission
From “blue water” rivers and streams to “green water” marine environments and brackish estuaries in between, EESC and the Atlantic States Marine Fisheries Commission are collaborating to bring together local, regional, and national expertise to provide the science that modern fisheries management demands.

The Interagency Coordinating Committee on the validation of alternative methods (ICCVAM)
Many ICCVAM member agencies are developing new technologies and resources to replace
the use of animals for chemical safety testing. These include new platforms such as
microphysiological systems (MPS), data resources to support the development of predictive
models and quantitative structure–activity relationships (QSARs), and web tools to facilitate
data access and visualization.
Declines in brook trout abundance linked to atmospheric warming in Maryland, USA
Salmonid fishes provide an important indicator of climate change given their reliance on cold water. We evaluated temporal changes in the density of stream-dwelling brook trout (Salvelinus fontinalis) from surveys conducted over a 36-year period (1988–2023) by the Maryland Department of Natural Resources in Eastern North America. Nonparametric trend analyses revealed decreasing densities of adult

Per- and Polyfluoroalkyl Substances (PFAS) found in Smallmouth Bass (Micropterus dolomieu) throughout the mid-Atlantic United States
Per- and polyfluoroalkyl substances (PFAS) are a large group of chemicals that have been recognized as concerns for both human and ecosystem health. There is a need to understand the effects of PFAS on fish health and populations.
Preliminary Research Sheds Light on Proper Analysis and Sample Handling for the Tire-Derived Contaminants 6PPD and 6PPD-quinone
Tire and road wear particles have been shown to cause acute effects to sensitive aquatic animals and degrade their habitats. U.S. Geological Survey (USGS) scientists developed methods to accurately identify aquatic compounds, such as 6PPD and 6PPD-quinone, that can cause acute mortality events in coho salmon (Oncorhynchus kisutch).
