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.
