National Centers for Coastal Ocean Science (NCCOS) long-term monitoring: Regional Ecological Assessments and National Benthic Inventory (NCEI Accession 0202842)

The NCCOS Regional Ecological Assessments (REA) and NOAA National Benthic Inventory (NBI) include observations of water quality, sediment quality, fish and shellfish tissue chemical contaminants, and benthic infaunal abundance obtained from studies conducted since 1991 by NOAA and partnering institutions in estuarine and coastal-ocean areas of the United States. Measured parameters include: location and date of the sampling event, measures of water quality (e.g., temperature, salinity, dissolved oxygen, nutrients), sediment quality (e.g., grain size, total organic carbon, chemical contaminant concentrations, toxicity), fish and shellfish tissue chemical contaminants (e.g., concentrations of metals, PAHs, PCBs, PBDEs, organic pesticides), and infaunal assemblages (e.g., taxon, abundance).

美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）海岸海洋科学中心（National Centers for Coastal Ocean Science, NCCOS）区域生态评估（Regional Ecological Assessments, REA）与NOAA国家底栖生物调查（National Benthic Inventory, NBI）数据集，收录了自1991年起由NOAA及其合作机构在美国河口与近岸海域开展的研究中获取的水质、沉积物质量、鱼类及贝类组织化学污染物、底栖内栖生物丰度等观测数据。
该数据集的实测参数包括：采样事件的位置与日期，水质指标（如温度、盐度、溶解氧、营养盐），沉积物质量指标（如粒径、总有机碳、化学污染物浓度、毒性），鱼类及贝类组织化学污染物（如金属、多环芳烃（Polycyclic Aromatic Hydrocarbons, PAHs）、多氯联苯（Polychlorinated Biphenyls, PCBs）、多溴二苯醚（Polybrominated Diphenyl Ethers, PBDEs）、有机农药）的浓度，以及底栖内栖生物群落（如分类单元、丰度）。
