USGS scientists collect core samples from estuaries, lakes, coasts, and marine environments to study a range of physical and chemical properties preserved in sediment or coral over time. They process and analyze these core samples at the Pacific Coastal and Marine Science Center’s Sediment Core Lab.

Two video cameras are installed atop a utility pole near the northernmost point of land in the United States at Nuvuk (Point Barrow), Alaska. The cameras point northwest toward the Arctic Ocean and the boundary between the Chukchi and Beaufort Seas. Every half hour during daylight hours, the cameras collect snapshots and video for 10 minutes.
