Due to low elevation and a shallow water table, the Delaware Bay coast is highly vulnerable to sea-level rise. Numerical simulations of rising sea levels, groundwater flow, and salt transport through year 2100 indicate significant impacts on land use due to a rising water table and localized impacts due to saltwater intrusion in the surficial aquifer.
DELAWARE BAY, Del.- Today the United States Geological Survey (USGS) launched a demonstration of what will be a study over the next few days of the Delaware Bay using a helicopter carrying an electromagnetic sensor.
WOODBINE, NJ – Starting around July 8 and lasting up to a month, a helicopter towing a large hoop from a cable will begin making low-level flights over Delaware Bay and nearby regions in Delaware and New Jersey as part of the U.S.
Sea-level rise is causing saltwater to move from coastal marshes and tidal creeks inland over forests and croplands.
DGS scientist John Callahan was selected as a member of the Delaware River Basin Commission (DRBC) Advisory Committee on Climate Change (ACCC). John was selected as one of nine non-reserve members, to serve along with nine reserve members, to make up the 18-member committee.
Delaware is home to extensive networks of tidal marshes, which provide an array of critical ecosystem services including carbon sequestration. These marshes accumulate carbon due to their relatively high plant productivity and relatively low rates of litter decomposition.
The report “Recommendation of Sea-Level Rise Planning Scenarios for Delaware: Technical Report” was selected as the winner of the 2019 John C. Frye Memorial Award.
An expanse of tidal wetlands fringes the Delaware Estuary and provides Delaware, Pennsylvania, and New Jersey with abundant ecosystem services including habitat for indigenous and migrating plants and wildlife, biogeochemical cycling of nutrients, preserving water quality, flood hazard mitigation
State and local officials are rejecting a new report that says coastal states including Delaware need to spend billions of dollars on thousands of miles of sea walls to defend themselves against projected sea-level rise by 2040.
