National Coral Reef Monitoring Program: Towed-diver surveys of benthic habitat, key benthic species, and marine debris of the Pacific Remote Island Areas

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 08:15 AM | Dataset Last Updated: March 07, 2018 at 12:00 AM
The visual estimate data provided in this collection were gathered during towed-diver surveys around the Pacific Remote Island Areas. 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 Pacific Remote Island Areas as part of the ongoing NOAA National Coral Reef Monitoring Program (NCRMP).
