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.

Purpose:

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.

Process_Description:

Data Set Background Discussion The EMAP-Estuaries sampling design on which C2000 is based combines the strengths of systematic and random sampling with our understanding of estuarine systems. It provides a design that will allow probability-based estimates of the status of the Nation's estuarine systems, the variability associated with that status, its spatial and temporal components, and the temporal trends associated with changes in these systems. The Coastal 2000 sampling design is based on a single, annual sampling season of each station during the Index Period. The design differs from previous EMAP designs in that existing monitoring programs were incorporated where appropriate. "Biased" programs, such as those designed to evaluate the effects of a treatment plant, would NOT be appropriate for inclusion. Working with the states, the C2000 design team was able to identify a large number of sites that are currently being monitored and meet the criteria for being unbiased in their location. Many were randomly located in the original monitoring design. Specific methodology is in the REFERENCES below. Additional information is provided in:1) data/0-data/Station_Locations_Information/GED00004_Sta_m.txt2) data/0-data/"each data directory"/"file starting with GED "These "GED..." files are generalized for areas beyond American Samoa. INSTRUMENT TYPES: Station locations were determined using a GPS and are accurate within a radius of 100 ft. North American Datum of 1983 was used.
