Sponge models were left at the phylum level due to taxonomic uncertainty. Greater certainty in coral taxonomy allowed for modeling of individual Stylasteridae and Primnoidae coral families. A further overall coral group modeling was conducted to include all hydrocoral and gorgonian corals identified. All models are presented in the GeoTIFF raster format. Environmental layers used in the modeling of the taxa are also part of this data package. They include the parameters GeoTIFF rasters of latitude, longitude, bathymetry, aspect relative to mean current, mean bottom temperature for the region, current speed and direction for the deepest depth bin at each sampling point, ocean color, seafloor rugosity, sediment type, seafloor slope, mean current speed (exclusive of tides), and max tidal current measured over a year. For details on the measurement of each environmental layer, see Rooper et al. (2014). Deep sea coral and sponge ecosystems are widespread throughout most of Alaska's marine waters. In some places, such as the western Aleutian Islands, these may be among the most abundant cold-water coral and sponge communities in the world. Because of the size and scope of Alaska's continental shelf and slope, the vast majority of the area has not been surveyed for the presence of coral and sponge communities. Since the spatial distribution of these communities is not known in Alaska, it is difficult to predict the locations and types of human activities that may be threats to the deep-sea coral and sponge ecosystems. The objectives of this project were to predict the distribution of coral and sponge ecosystems for the Aleutian Islands. 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:0289893 Preview graphic PNG 0289893 NCEI ACCESSION NUMBER 2023-09-13 publication BATHYMETRY BENTHIC SPECIES - TAXA COUNTS CURRENT DIRECTION CURRENT SPEED DEPTH - BOTTOM HABITAT - BENTHIC LATITUDE LONGITUDE SEDIMENTS - PERCENT COVER WATER COLOR theme NODC DATA TYPES THESAURUS model output theme NODC OBSERVATION TYPES THESAURUS NOAA Alaska Fisheries Science Center NOAA Fisheries dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA Fisheries dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Deep Sea Coral Research and Technology Program (DSCRTP) project NODC PROJECT NAMES THESAURUS Bering Sea - Coastal Waters of Western Alaska 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 DOC/NOAA/NMFS/AFSC > Alaska Fisheries Science Center, 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.
