The United States has ECS in seven offshore areas: the Arctic, Atlantic (east coast), Bering Sea, Pacific (west coast), Mariana Islands, and two areas in the Gulf of Mexico.  The U.S. ECS area is approximately one million square kilometers – an area about twice the size of California.

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.

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.
