Benthic Surveys in Aua, American Samoa: benthic cover derived from analysis of benthic images collected during belt transect surveys of coral demography from 2022-09-12 to 2022-09-22 (NCEI Accession 0275987)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 04:14 AM | Dataset Last Updated: February 10, 2023 at 12:00 AM
This data package includes benthic cover data of Aua Reef, American Samoa, produced from the analysis of benthic imagery performed by the Ecosystem Sciences Division (ESD) of the Pacific Island Fisheries Science Center (PIFSC), and funded by the Coral Reef Conservation Program (CRCP). Benthic imagery was collected at 18 randomly-selected sites during coral demographic surveys by the NOAA ESD during the 2022 fly-in mission to American Samoa (MP2206). After processing and sorting site photos, imagery was qualitatively analyzed using the web-based CoralNet image annotation tool. CoralNet projects random points on each image, and the benthic elements falling directly underneath each point are identified by trained scientists. The source imagery analyzed to produce benthic cover estimates are archived separately with the NOAA National Centers for Environmental Information (NCEI) in NCEI Accession 0270551.
