Areas surveyed included south Oahu, west Maui, Lana’i, and west Hawaii island. Over the course of 10 survey days, the team surveyed approximately 90 km of 15-m wide transects at depths ranging from 2 to 10 m. Data provided in this dataset include visual estimates recorded by towed divers of percentage of live coral that was pale and bleached, as well as presence/absence data of condition by generic composition. Analysis of observer data reveals estimates of live coral affected by the event (pale or bleached) show a regional mean of 38.8% (+/- 1.96% Confidence Interval 95%), with large variation in impact apparent between transects on the same island separated by as little as 13 km. Additionally, instruments mounted on the towboards collected other in-situ data that are documented separately. A downward-facing DSLR camera with strobes collected photographic quadrat data by capturing an image of the benthos at 15-second intervals during the surveys. Oceanographic data was collected continuously throughout each survey with a suite of mounted sensors recording conductivity, temperature, depth, fluorometry (chlorophyll-a), turbidity and dissolved oxygen. The 2014–2015 global coral bleaching event brought widespread and severe impacts to the entire Hawaiian archipelago. In 2015, the corals of the Main Hawaiian Islands were subjected to unprecedented levels of thermal stress that resulted in the most severe coral bleaching ever recorded in the islands. To report on the event, local researchers and reef managers conducted free-swimming diver surveys in areas generally accessible via same-day field excursions. In an effort to survey larger high coral cover areas that are difficult for local researchers and managers to access via day-long field trips, a team from CREP deployed on a two-week research cruise in November 2015 aboard the NOAA ship Hi‘ialaka‘i to evaluate the impacts of the 2015 coral bleaching event in the Main Hawaiian Islands via towed-diver surveys. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0157624 Preview graphic PNG 0157624 NCEI ACCESSION NUMBER 2016-12-16 publication CORAL CORAL - BLEACHING CORAL - CENSUS DEPTH - SENSOR REEF AND/OR BOTTOM REGIME - PERCENT COVER WATER TEMPERATURE theme NODC DATA TYPES THESAURUS GPS swimmer/diver visual estimate visual observation instrument NODC INSTRUMENT TYPES THESAURUS in situ survey survey - biological survey - coral reef survey - swimmer/diver visual estimate visual observation theme NODC OBSERVATION TYPES THESAURUS NOAA Ship Hi'ialakai platform NODC PLATFORM NAMES THESAURUS Coral Reef Ecosystem Program dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS Coral Reef Ecosystem Program dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Coral Reef Conservation Program (CRCP) CORAL REEF STUDIES project NODC PROJECT NAMES THESAURUS Hawaiian Islands Humpback Whale National Marine Sanctuary North Pacific Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NMFS > National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
