The USGS office in Woods Hole, MA recently conducted a survey of Long Pond—a local waterbody in the town of Falmouth. Long Pond has been Falmouth’s primary drinking water source since 1898.

In August, the Woods Hole Coastal and Marine Science Center had four great presentations from summer interns discussing various aspects of salt marsh science!

The Environmental Protection Agency (EPA) and USGS prepared four activities for the Preserving Our Homelands Summer Camp on July 22nd. EPA hosted an air quality monitoring activity that involved the campers conducting tests and participating in a guided discussion about factors contributing to air quality and its implications on people and habitat.

An example seasonally rotating beach of southern California (Salt Creek Beach, 33.4788°N, 117.7237°W) showing (a,b) general patterns of rotation from satellite imagery, (c) spatial distribution of seasonal shoreline excursions (marker size) and timing of the shoreline seasonality (marker colour) from the STL and k-means results and (d) time series of shoreline posit

A recent USGS study highlights the impacts of #hurricanes and #storms on #barrierislands, focusing on the outwash process, where flooding from behind the dunes removes sand, plants, and seeds, washing them into the #ocean. 

The USGS used #drones to collect aerial remote sensing data across the Lower #DarbyCreek Area Superfund Site and the adjacent #JohnHeinzNationalWildlifeRefuge, about 5 miles outside of #Philadelphia, PA. The data release is now available: https://doi.org/10.5066/P134HU3Y.  

New data release presents an update to the Coastal Response Likelihood model—a spatially explicit, probabilistic model that evaluates coastal response for the Northeastern U.S. under various sea-level scenarios. https://doi.org/10.5066/P13JKJUT

BAYEX predictions of 100-year storm surge return levels and associated 90% credible interval widths for the entire US coastline. From the study Observations reveal changing coastal storm extremes around the United States.

The USGS is actively mapping the seafloor surface and its underlying structure in coastal to deep sea environments. These maps provide the scientific foundation needed to address national priorities, including #publicsafety, #nationalsecurity, #energydominance, and #economicprosperity. 

Water flux through a tidal creek with a small, moderate, and extreme tide range during (A) a flood tide and (B) an ebb tide. Creek velocity legend applies to all tide ranges.

Map of study area: China Camp State Park and the adjacent shallows of San Pablo Bay. Black and gray bathymetry lines indicate the location of mean higher high water (MHHW) and mean lower low water (MLLW), respectively. Elevations in meters of those tidal datums are referenced to the North American Vertical Datum of 1988

Non-profit organizations Transom Story Lab and Atlantic Public Media hosted a weekend-long science storytelling workshop called "Making Waves." It was attended by 11 scientists from scientific institutions throughout Woods Hole, Massachusetts, including USGS scientists Jin-Si Over, Ellen Lalk, and Sara Zeigler.

USGS marks the spot! Our science is key to understanding seabed resources. Our maps characterizing the seafloor can help find #criticalminerals, precious metals, and other vital resources in high demand. 

Composites of hydrodynamic and morphological responses to (a–c) ENSO phases and (d–f) the strongest El Niño events during winter (DJF) over 1997–2022.

Map of the North American West Coast, the monitored coastline is shown in light yellow. Dashed boxes delineate the different subregions of the study area. Pie charts show the regional distribution of advancing/retreating waterline trends during 2000–2022 derived from the dataset presented in this study.
