Benthic Sampling Adjacent to the Waianae Ocean Outfall, Oahu, Hawaii, 2001-2010 (NODC Accession 0084994)

Published by NOAA/NESDIS/NODC/NCDDC | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 01, 2026 at 07:30 AM | Dataset Last Updated: January 06, 2021 at 12:00 AM
Annual surveys are undertaken to sample bottom-sediment for biological and geochemical analyses at six stations at a depth of approximately 34 m in the vicinity of the Waianae Wastewater Treatment Plant outfall diffuser on the leeward coast of Oahu, Hawaii. All stations had sediment fractions with >90% sand. Silt fractions were no more than 4% at any station. Oxidation- reduction-potential (ORP) and total-volatile-solids measurements of these sediments indicated a nonreducing benthic environment at all stations. This data set contains examination of the sediments for species, abundance, and richness of nonmollusks, crustacean, molluscan, nematode, oligochaete, and polychaete faunas. A PDF document provides annual summaries for 2001-2010 while data files hold similar data for 2006-2009.
