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.

(A) Inset: Map showing location of (B–F). (B), (C) The C-CAP land cover for 1996 and 2016, respectively. (D) Land cover in the C-CAP datasets changed for coastal, noncoastal and low elevation (less than 1 m), and noncoastal land classes between 1996 and 2016.

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.
