EK80 Water Column Sonar Data Collected During PC2102

Description

Between 30 May - 12 June 2021, we will conduct Remotely Operated Vehicle (ROV) and multibeam sonar surveys inside and outside six marine protected areas (MPAs) as well as inside and outside the Oculina Experimental Closed Area (OECA) in the south Atlantic to assess the efficacy of this management tool to protect species of the snapper grouper complex and Oculina coral. We will also investigate two additional spots of interest: Devil’s Hole Spawning Management Zone and Cape Lookout. The cruise is planned for the continental shelf edge of the South Atlantic Bight between Port Canaveral, FL and Cape Lookout, NC. We will be working in and around the following six MPAs, Oculina Experimental Closed Area, and two additional areas of interest (Figure 1): Florida MPA: Northwest corner at 30°29' N, 80°14' W; northeast corner at 30°29' N, 80°2' W; southwest corner at 30°19' N, 80°14' W; and southeast corner at 30°19' N, 80°2' W. Georgia MPA: Northwest corner at 31°43' N, 79°31' W; northeast corner at 31°43' N, 79°21' W; southwest corner at 31°34' N, 79°39' W; and southeast corner at 31°34' N, 79°29' W. Edisto MPA: Northwest corner at 32°24' N, 79°6' W; northeast corner at 32°24' N, 78°54' W, southwest corner at 32°18.5' N, 79°6' W and southeast corner at 32°18.5' N, 78°54' W. Charleston Deep Artificial Reef MPA: Northwest corner at 32°04' N, 79°12'W; northeast corner at 32°8.5'N, 79°7.75'W; southwest corner at 32°1.5'N, 79°9.3'W; and southeast corner at 32°6'N, 79°5'W. South Carolina MPA: Northwest corner at 32°53.5' N, 78°16.75' W; northeast corner at 32°53.5' N, 78°4.75' W; southwest corner at 32°48.5' N, 78°16.75' W; and southeast corner at 32°48.5' N, 78°4.75' W. Snowy Wreck MPA: Northwest corner at 33°25' N, 77°4.75' W; northeast corner at 33°34.75' N, 76°51.3' W; southwest corner at 33°15.75' N, 77°0' W; and southeast corner at 33°25.5' N, 76°46.5' W. Oculina Experimental Closed Area: Northern boundary at 27⁰ 53’N, Southern boundary at 27⁰ 30’N, Eastern boundary at 79⁰ 56’W, Western boundary at 80⁰W. Devil’s Hole Spawning Management Zone: Northwest corner at 32º 34.311’ N, 78º 34.996’ W; northeast corner at 32º 34.311’ N, 78º 33.220’ W; southwest corner at 32º 32.748’ N, 78º 34.996’ W; and southeast corner at 32º 32.748’ N, 78º 33.220’ W. Cape Lookout Site: Northwest corner at 34º 4.186’ N, 76º 17.188’ W; northeast corner at 33º 59.243’ N, 76º 12.991’ W; southwest corner at 33º 50.02’ N, 76º 34.922’ W; southeast corner at 33º 44.785’ N, 76º 30.526’ W. The goal of the cruise is to gather additional data on habitat and fish assemblages in six of the South Atlantic MPAs and OECA as part of a long term sampling program to document changes in these areas before and after fishing restrictions are implemented. The southernmost boundary of our work areas will be Port Canaveral, FL while the northernmost boundary will be Cape Lookout, NC. Efficacy testing of this management tool will aid fishery managers in future use of area restrictions for the protection of valuable habitat and fishery resources. Specific objectives include: Daytime Operation: Conduct ROV transect surveys of habitat and fish assemblages and collections of corals and sponges during daylight hours. Night Operation: Conduct multibeam mapping to find areas to dive on with the ROV the following day. Night Operation: Conduct total water column CTD profiles and XBT casts to collect sound velocity data for the mapping
