Nuvuk video camera 1 dark image
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.

Pea Island video camera 1 snapshot
Two video cameras are temporarily mounted on a dune at Pea Island National Wildlife Refuge on the Outer Banks of North Carolina. The cameras are imaging the southern DUNEX (DUring Nearshore Event eXperiment) experiment site, and are designed to have a stereo view of the beach and potential overwash path until late October. Instruments from the U.S.
