A diagram illustrating how the patterns of erosion and deposition associated with three sediment gravity flows could produce the stacked pockmarks and lateral migration observed in AUV-collected Chirp profiles. Long, uneventful episodes of hemipelagic drape (a, d, g, j) are intermittently interrupted by sediment gravity flows that either: 1b.

Location Map showing the Sur Pockmark Field outlined in green, individual pockmarks are shown as small red dots. This study focuses on the largest section of the pockmark field, from the Lucia Chica Channel down to the San Simeon Channel. AUV surveys are outlined in white and the offshore wind commercial leases are outlined in gray.

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.
