Title: US Environmental Protection Agency National Coastal Assessment for American Samoa 2004: water quality, sediment grain, and chemistry data (NCEI Accession 0000455)
Abstract: In 2004, the Environmental Protection Agency (EPA) Environmental Monitoring and Assessment Program (EMAP) National Coastal Assessment (NCA), coordinated through the Gulf Ecology Division, conducted a comprehensive survey of the condition of estuarine resources in American Samoa. The survey sampled 49 stations on islands of Tutuila, Aunu'u Ofu, Olosega, Ta'u during April and August, 2004. The WATER QUALITY MEASUREMENTS data set contains two types of data: hydrologic profile water quality information resulting from in-field observations of physical data and water quality information resulting from laboratory examination of water quality samples for nutrient analyses. The SEDIMENT CHEMISTRY data set contains sediment contaminant information resulting from laboratory examination of samples collected at sites. Each record reports the contaminant name and its associated measured concentration, date site was visited, and the group that collected the data. Only one grab per site was required by the program. The SEDIMENT GRAIN data set contains sediment grain analyses information resulting from laboratory examination of samples collected at sites visited during probability surveys. Each record reports the sediment component and its associated measured concentration, date site was visited, and the group that collected the data. Only one grab per site was required by the program.
