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

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.

本研究于夏威夷瓦胡岛（Oahu）背风海岸怀亚内阿污水处理厂（Waianae Wastewater Treatment Plant）排污扩散器附近海域，于约34米水深的6个站位开展周年底泥采样，用于生物学与地球化学分析。所有站位的底泥组分中砂粒占比均超过90%，粉粒占比均不超过4%。对上述底泥的氧化还原电位（Oxidation-Reduction Potential, ORP）及总挥发性固体含量进行测定后发现，所有站位均处于非还原性底栖环境中。本数据集涵盖了对非软体动物、甲壳类、软体动物、线虫类、寡毛类及多毛类动物的物种组成、丰度及丰富度的检测结果。一份PDF文档提供了2001年至2010年的年度汇总数据，而数据文件则包含2006年至2009年的同类数据。
