A seafloor mapping survey in Long Island Sound took place in May with collaborators from the University of Connecticut and the University of New Haven. They are mapping the area’s geology and biota to identify seasonal changes from their previous survey in November 2024.

The Extended Continental Shelf team was awarded the USGS Unit Award for Excellence of Service, an award that recognizes groups of employees who have worked together as a unit to achieve exceptional results. This team was part of a Federal interagency effort to identify the outer limits of the U.S.

Projected 21st-century land loss and organic carbon disturbance on Alaska’s Arctic Coastal Plain. From the study Permafrost thaw subsidence, sea-level rise, and erosion are transforming Alaska’s Arctic coastal zone.

Great earthquakes in the 20th century. Inset numbers over the 3 by 12 grid indicate subfaults with large slip in meters from the updated 1957 rupture model with red and blue tones for shallow and deeper megathrust rupture, respectively.
