This data package was created 2025-12-03 09:27:31 by NPSTORET and includes selected project, location, and result data. Data are from Storlazzi, C.D., Presto, M.K., and Logan, J.B., 2009. "Coastal Circulation and Sediment Dynamics in War-in-the-Pacific National Historical Park, Guam. Measurements of Waves, Currents, Temperature, Salinity, and Turbidity: June 2007–January 2008." USGS Open-File Report 2009-1195, 79 p. In 2007 the U.S. Geological Survey Western Coastal and Marine Geology Team initiated an investigation of coastal circulation, sediment flux, and sediment residence time along west-central Guam, primarily focusing on WAPA's Asan Unit. Terrestrial sediment discharge to the coastal waters has resulted in sedimentation, eutrophication, and pollution impacting WAPA's coral reef ecosystem. Therefore, the Asan watershed is an area of concern to the NPS and was designated as one of the U.S. Coral Reef Task Force Guam Local Action Strategy priority watersheds.

Data contained in WAPA_NPSTORET_BE.ACCDB (NPSTORET back-end file) were filtered to include:

Organization: - WAPA: War in the Pacific National Historical Park Project: - WAPA0017: Coastal Circulation and Sediment Dynamics in War-in-the-Pacific National Historical Park, Guam: Measurements of Waves, Currents, Temperature, Salinity, and Turbidity: June 2007–January 2008 Station: - Include Trip QC And All Station Visit Results Value Status: - Accepted or Certified (exported as Final) or Final

The data package is organized into five data tables: - Projects.csv - describes the purpose and background of the monitoring efforts - Locations.csv - documents the attributes of the monitoring locations/stations - Results.csv - contains the field measurements, observations, and/or lab analyses for each sample/event/data grouping - HUC.csv - enumerates the domain of allowed values for 8-digit and 12-digit hydrologic unit codes utilized by the Locations data table - Characteristics.csv - enumerates the domain of characteristics available in NPSTORET to identify what was sampled, measured or observed in Results

Period of record for filtered data is 2007-07-27 to 2007-11-05. This data package is a snapshot in time of one National Park Service project. The most current data for this project, which may be more or less extensive than that in this data package, can be found on the Water Quality Portal at:
