Data From Lisa Chang’s 1994 Pre-Ph.D. Dissertation Research From Shaver Hollow

This data package was created 2025-01-14 15:12:40 by NPSTORET and includes selected project, location, and result data.

Data were collected in advance of a Ph.D. proposal by Lisa Chang. This work ultimately led to Chang's University of Virginia dissertation entitled 'Carbon and nitrogen effects on nitrification in Shaver Hollow Watershed, Shenandoah National Park'.

Data contained in Shenandoah National Park - University of Virginia NPSTORET back-end file (NPS_UVA_NPSTORET_BE_20250108.ACCDB) were filtered to include:

Project:

• SHEN_UVA_CHANG_1994: Lisa Chang’s Pre-Ph.D. Dissertation Research Data from Shaver Hollow
  Station:
• Include Trip QC And All Station Visit Results
  Park/Unit Code:
• SHEN
  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 1994-06-15 to 1994-12-03. 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:
