National Coral Reef Monitoring Program: Towed-diver surveys of benthic habitats, key benthic species, and marine debris of the Mariana Archipelago

browse graphicPreview graphic
The visual estimate data provided in this collection were gathered during towed-diver surveys around the Mariana Archipelago. During towed-diver surveys, the diver records the percentage cover of total live hard corals, stressed hard corals, soft corals, sand, coralline algae, macroalgae, and the number of individual macroinvertebrates (crown of thorns starfish (COTS), sea urchins, and giant clams). Benthic habitat complexity and type data are also collected as part of the survey with the following habitat type categories: continuous reef, spur and groove, patch reefs, rock boulders, pavement, rubble flat, sand flats, pinnacle, and wall. Surveys were conducted in the Mariana Archipelago as part of the ongoing NOAA National Coral Reef Monitoring Program (NCRMP).

The towed-diver method is used to conduct benthic surveys and assess large-scale disturbances (e.g., bleaching). This method is also used to quantify benthic components such as habitat complexity/type and the general distribution and abundance patterns of live coral, CCA, macroalgae, and macroinvertebrates. The towed-diver method is suitable for assessing relatively large areas of reef habitat. The method involves towing a pair of SCUBA divers—one for benthic and one for fish—behind a small boat for approximately 50 minutes, 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-minute segments, with visual observations recorded by 5-minute segment. The fish towed diver data is documented and archived separately.
Purpose The NOAA National Coral Reef Monitoring Program (NCRMP) details a long term approach to provide an ecosystem perspective via monitoring climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. The NCRMP is intended to coordinate various NOAA Coral Reef Conservation Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of the NCRMP, NOAA will be able to clearly and concisely communicate results of national-scale monitoring to national, state, and territorial policy makers, resource managers, and the public on a periodic basis.
