| Title: | Pacific Reef Assessment and Monitoring Program: Towed-diver Surveys of Large-bodied Fishes of the U.S. Pacific Reefs from 2000-09-09 to 2012-05-19 (NCEI Accession 0163744) |
| Abstract: | The towed-diver method is used to conduct surveys of large-bodied (> 50 cm) fishes in the Hawaiian and Mariana Archipelagos, American Samoa, and the Pacific Remote Island Areas as part of the NOAA National Coral Reef Monitoring Program (NCRMP). A suitable method for assessing relatively large areas of reef habitat, the method involves towing a pair of SCUBA divers—one benthic and one fish—behind a small boat for approximately 50 min following the ~15-m depth contour and covering about 2–3 km of habitat. Each diver is equipped with a towboard and attempts to maintain a constant elevation above the surface of the reef (~1 m) for the duration of the survey. A complete towed-diver survey is divided into 10 5-min segments, with visual observations recorded by 5-min segment. The visual estimate data provided in this dataset were collected during towed-diver surveys in which the number, size, and species of all large-bodied fishes observed within a visually estimated 5-m transect on either side of the fish diver and 10 m in front were recorded. The data were collected at coral reefs across all U.S.-affiliated regions as part of the NOAA Pacific Islands Fisheries Science Center (PIFSC), Coral Reef Ecosystem Program (CREP) led missions since 2000. |
