Chesapeake Bay Activities

Land and Climate Change

Land-use change and climate variability are two of the most significant causes of ecosystem change in the Chesapeake watershed. The primary USGS science topics include land change monitoring and modeling, and sea-level rise and wetlands. The findings are used to inform Chesapeake goals for land conservation, healthy watersheds, climate resiliency, and water quality.

New Crowd Sourcing Will Contribute to Study of Land Subsidence and Sea-Level Rise in the Chesapeake Bay

Issue: Chesapeake Bay region has the highest rate of relative sea-level rise on the Atlantic Coast of the United States. Scientists use the term relative sea-level rise to describe the change in ocean height relative to changes in land elevation.  Data indicate that vertical land motion in the form of subsidence has been responsible for more than half the relative sea-level...

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...

Projecting stream conditions under future land-use and climate scenarios

Issue: Global change, particularly changes in land use and climate, is dramatically altering stream conditions throughout the world. Healthy streams are important for freshwater fisheries, wildlife, and public recreation. The Chesapeake Bay Program (CBP) has a goal of improving the health of streams throughout the Chesapeake Bay watershed, which includes an outcome of...

Type of Wetlands Affect How Much Nitrogen is Removed from the Bay’s Tidal Rivers

Issue: Wetlands are important for removing nitrogen from rivers entering the Chesapeake Bay. More information is needed on how much nitrogen wetlands can remove.

Tripod-palooza—USGS Collaborates with Federal, State, and Academic Partners to Support Coastal Resiliency in the Wider Chesapeake Bay Area

In the Chesapeake Bay area, the Virginia and West Virginia Water Science Center is partnering with over a dozen organizations in a pilot project this fall, resulting in the establishment of a baseline reference for an ongoing effort in monitoring coastal subsidence.

Record Amounts of Rainwater Flow off the Land into Chesapeake Bay

As the Mid-Atlantic states' super-soaker summer draws to a close, record amounts of rainwater have flowed off the land and into Chesapeake Bay, with potential consequences for the nation's largest estuary. USGS measurements show freshwater flows into the bay in August 2018 were the highest ever recorded for that month by a wide margin. River flows into the bay have been unusually high since...
