Mapping the Nantucket Sound Seafloor
Throughout June 2022, the Woods Hole Coastal and Marine Science Center’s Sea Floor Mapping Group will map the seafloor and subseafloor of Nantucket Sound as part of a long-term collaboration with the State of Massachusetts.
Take a Deep Dive into USGS ocean science
USGS makes a splash with a series of new web pages to guide you through the depth of ocean science research here at the U.S. Geological Survey--spanning from the continental shelf to the deep sea.
USGS collaborates with local colleges, inspiring students to pursue marine science by taking them to sea
The Scientists-at-Sea program was established to provide students with the opportunity to participate in their first oceanographic research cruise—and USGS was on board to assist.
Tidal restoration could reduce methane emissions in impounded, Phragmites-invaded wetlands by restoring high salinity levels
A new study confirms that restoration of tidal flow to impounded coastal wetlands dominated by the non-native plant Phragmites australis could reduce methane emissions and help mitigate climate change.
DECODE: A New Automatic Algorithm To Track Coastal Tidal Wetland Changes
Scientists from the USGS, University of Connecticut, and U.S. Fish and Wildlife Service developed an automatic algorithm for DEtection and Characterization of cOastal tiDal wEtlands change (DECODE) using Landsat time series.
USGS drifter found on a Scotland beach nearly 40 years after its release in the Arctic Ocean
On 22 February 2022, a resident of the Scottish isle of Islay found a yellow plastic disk—a “drifter”—that had been released off the Arctic coast of Alaska nearly 40 years before by USGS scientists studying currents.
Sea-level rise may help shorebirds but could put communities at risk on Fire Island
New coastal change scenarios show enduring future habitat for the threatened piping plover, but potential loss of land that supports coastal homes and infrastructure.
Explore Deep-sea Data Along the Pacific Coast with EXPRESS Data Viewer
As part of National Ocean Month, USGS has launched a new web application that allows users and the public to explore a trove of geohazard, ecosystem, and resource data from the deep ocean and continental margin off the coast of California, Oregon, and Washington.
