This data package was created 2024-10-17 17:25:18 by NPSTORET and includes selected project, location, and result data.

Data are from the block design study of the Influence of Basin Characteristics on Acidification Response. The data derive from Mary Ann Elizabeth Grell’s University of Tennessee Master’s thesis entitled ‘Soil Chemistry Characterization of Acid Sensitive Watersheds in the Great Smoky Mountains National Park’. The dataset includes 9,466 results collected from 4/2/2008 to 9/14/2009 at 16 monitoring locations comprising throughfall and stream sites at Cosby Creek, Jakes Creek, Lost Bottom Creek, Newt Prong, Palmer Creek, Rock Creek, Road Prong, and Walker Camp.

Data contained in Great Smoky Mountains National Park NPSTORET back-end file (GRSM_NPSTORET_BE_20240510_20240510_1245.ACCDB) were filtered to include:

Organization: - GRSM: Great Smoky Mountains National Park Project: - GRSM_BD: Influence of Basin Characteristics on Acidification Response 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 datatable - 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 2008-04-02 to 2009-09-14. 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: https://www.waterqualitydata.us/data/Result/search?project=GRSM_BD
