New Review of Sediment Science Informs Choices of Management Actions in the Chesapeake

Issue: The Chesapeake Bay Program (CBP) is pursuing restoration efforts to improve habitats and associated water quality for fisheries, both in the watershed and estuary. Excess sediment decreases light in tidal waters for submerged aquatic vegetation, harms oysters, carries contaminants, and impairs stream health throughout the watershed. The CBP is implementing management...

New information on chemical and physical characteristics of streams and floodplains across the Chesapeake Bay and Delaware River watersheds

Issue: Improving stream health is an important outcome of the Chesapeake Bay Program partnership. Stream conditions are important for recreational fisheries, and mitigating the amount of nutrients, sediment, and contaminants delivered to the Bay.

New dataset available on stream and floodplain geometry to inform restoration decisions

Issue: The need for stream mapping

The physical shape of streams and floodplains can provide information about how water, sediment, and other matter moves through the landscape. Streams can have deep channels (tall streambanks) disconnected from the floodplain or wide shallow channels that easily spill over the banks into the floodplain during high flows. Mapping where...

Impacts of coastal and watershed changes on upper estuaries: causes and implications of wetland ecosystem transitions along the US Atlantic and Gulf Coasts

Estuaries and their surrounding wetlands are coastal transition zones where freshwater rivers meet tidal seawater.  As sea levels rise, tidal forces move saltier water farther upstream, extending into freshwater wetland areas. Human changes to the surrounding landscape may amplify the effects of this tidal extension, impacting the resiliency and function of the upper estuarine wetlands. One...

Determining Target Salinity Values for Restoration of the Estuaries of the Greater Everglades

The Greater Everglades Ecosystem, which includes Everglades National Park and Biscayne National Park, experienced significant alterations in the 20th century with the construction of canals to divert water, water management practices, growth of agriculture, and the rapidly expanding urban population of Miami and south Florida.  In the 1990s a federal, state, and local effort to...

Appalachian Basin Geologic Mapping Project

The Appalachian Basin Geologic Mapping Project performs geologic mapping at local and regional scales, and geologic research in The Valley and Ridge and Appalachian Plateaus physiographic provinces. These provinces include parts of 11 states and mainly borders the Blue Ridge / Piedmont and North Interior Lowlands Provinces. Two states have Valley and Ridge geology only (GA, NJ), two have...

Sea Level Rise and Climate: Impacts on the Greater Everglades Ecosystem and Restoration

The Greater Everglades Ecosystem covers much of south Florida, and the highest areas are only a few meters above sea level.  Predictions of sea level rise and changes in storm intensity for the 21st century are particularly concerning to the urban population of Miami and the east coast, but also represent a challenge to Everglades National Park and Biscayne National Park resource...

Wetlands in the Quaternary Project

Wetlands accumulate organic-rich sediment or peat stratigraphically, making them great archives of past environmental change. Wetlands also act as hydrologic buffers on the landscape and are important to global biogeochemical cycling. This project uses wetland archives from a range of environments to better understand how vegetation, hydrology, and hydroclimate has changed on decadal to multi-...
