Title:
CRED Cumulative Map of Percent Scleractinian Coral Cover along towed camera sled tracks and AUV dive tracks at Rota Island, Commonwealth of the Northern Mariana Islands
Abstract:
This map displays optical validation observation locations and percent coverage of scleractinian coral overlaid on bathymetry. Optical data were collected by CRED TOAD camera sled aboard the NOAA ship Oscar Elton Sette on cruises OES 0307 and by the CRED-NWFSC SeaBED AUV during Oscar Elton Sette cruise SE1002.
Supplemental_Information:
Rota, 117 km southwest of Saipan and 76 km north of Guam, is the southernmost island in the Commonwealth of the Northern Mariana Islands. It has a land area of 85.5 square km and is approximately 17 km long and 5 km wide. The principal communities are Sinapalo and SongSong. As Rota was neither developed extensively by the Japanese nor invaded during World War II (WWII), it still has much of its native vegetation. However, the island is becoming more of a tourist destination and development is increasing, which may impact the existing fringing reefs. Fringing reef surrounds the island and modern reef development is most significant on the northwest coast, west of Teteto Beach, and in the Sasanhaya Bay on the southwest coast. Continuous reef is found inside Sasanhaya Bay and an area along the western shore. Erosion along the Talakaya cliff line on the southern coast is causing sedimentation problems on adjacent reefs. This map includes classified video data from TOAD camera sled tows conducted at Rota during 2003 (cruise OES0307), and classified photographs from selected AUV dives conducted at Rota in 2010 (cruise SE1002). During cruise SE1002, 3 AUV dives were conducted at Rota, however, as the AUV was still undergoing testing and trials, two of these dives repeated the same route. Therefore, only photos from 2 dives have been classified for this map. These were selected due to covering distinct routes, and were conducted during the day/night.
