US EPA/National Health and Environmental Effects Research Laboratory harwell.linda@epa.gov author US EPA/National Health and Environmental Effects Research Laboratory author tableDigital 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. These data originated from surveys designed to assess the ecological conditions in estuaries. Program Objective: EPA's National Coastal Assessment (NCA), is a five-year effort led by EPA's Office of Research and Development to evaluate the assessment methods it has developed to advance the science of ecosystem condition monitoring. C2000 represents the current state of evolution of EPA's EMAP. EMAP was originally designed to provide a quantitative assessment of the regional extent of environmental problems by measuring status and change in selected indicators of ecological condition. EMAP provides a strategy to identify and bound the extent, magnitude and location of environmental degradation and improvement on a regional scale. Data Set Objective: The objective of the sampling design is to provide a statistically defensible strategy for collecting information about selected indicators of ecological condition and their variability. The design is flexible to allow alternative future uses. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0000455 Preview graphic PNG 0000455 NCEI ACCESSION NUMBER 2010-02-18 publication CAS (CHEMICAL ABSTRACTS SERVICE) PARAMETER CODES CHEMISTRY - SEDIMENT DEPTH - OBSERVATION DEPTH - SENSOR DISSOLVED OXYGEN METALS OXYGEN Pesticides pH PHOTOSYNTHETIC ACTIVE RADIATION (PAR) POLYCHLORINATED BIPHENYLS POLYNUCLEAR AROMATIC HYDROCARBONS (PAH) SALINITY Secchi depth SEDIMENT - GRAIN SIZE SEDIMENT - POREWATER CHEMISTRY TRACE METALS WATER TEMPERATURE theme NODC DATA TYPES THESAURUS multi-parameter water quality sensor oxygen sensor PAR Sensor salinometer Secchi disk sediment sampler - grab thermometer instrument NODC INSTRUMENT TYPES THESAURUS benthic chemical laboratory analyses optical physical sediment analysis site samples water chemistry theme NODC OBSERVATION TYPES THESAURUS US EPA/National Health and Environmental Effects Research Laboratory dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS US EPA/National Health and Environmental Effects Research Laboratory dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Environmental Monitoring & Assessment Program (EMAP) US EPA National Coastal Assessment (NCA) project NODC PROJECT NAMES THESAURUS South Pacific Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NESDIS/NODC > National Oceanographic Data Center, NESDIS, NOAA, U.S. Department of Commerce EPA/ORD/NHEERL > National Health and Environmental Effects Research Laboratory, Office of Research and Development, U.S. Environmental Protection Agency dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

NOAA National Centers for Environmental Information custodian multi-parameter water quality sensor multi-parameter water quality sensor used to measure temperature, salinity, dissolved oxygen, and other parameters Instrument used to measure temperature, salinity, dissolved oxygen, and other parameters, often used to measure water quality parameters. Can be a hand-held instrument or a sonde for unattended monitoring. Often used in coastal water monitoring stations. YSI is the preeminent brand (as of 2024). oxygen sensor oxygen sensor Any instrument that measures oxygen content in a compound. PAR Sensor PAR Sensor Photosynthetically Active Radiation Sensor The PAR sensor measures global solar radiation from 400 to 700 nm, which approximates the spectral band active in photosynthesis. The response of the instrument falls sharply to zero on either side of this band, and between 400 and 670 nm it increases monotonically from about 50% to 100%. There is no protective glass dome over the receiving surface. Irradiance from the sun passes through a small white visible bandpass filter/diffuser in the shape of a horizontal disk at the top of the instrument. Within the instrument radiation is directed through a series of colored glass filters and onto a silicon photodiode detector. The factory-supplied calibration converts the signal from the detector to a flux of photons in micro-mole (of photons) s-1 m-2. (One micro-mole equals 6.022 E17 photons.) For the solar spectrum, these units may be converted to watts per square meter by dividing by 4.6.

The disc is mounted on a pole or line, and lowered slowly down in the water. The depth at which the disk is no longer visible is taken as a measure of the transparency of the water. This measure is known as the Secchi depth and is related to water turbidity.
