# de_wqsites.rdb (tab-delimited ASCII file ) # Date created: May 27, 1998 (19980527 13:59:34) # # Water-quality sites in Delaware # # This file contains locational information for nontidal sampling # sites where major forms of nutrient (nitrogen and phosphorus), sediment, # major ion and organic carbon concentrations, dissolved oxygen, selected # field parameters, and selected biological data were sampled. # The selection of water-quality data from nontidal sites for inclusion # in the database was based on the following minimum criteria (Langland and # others, 1995): # # - Nutrient- and sediment-concentration data collected between # October 1, 1971, through December 31, 1996. # # - A minimum of 12 nutrient- and sediment-concentration samples # representing fall, winter, spring, and summer conditions # collected throughout any consecutive 3-year time span. # # - Nutrient- and sediment-concentration data available in digital format. # # REFERENCE: Langland, M.J., Lietman, P.L., and Hoffman, S.A., Synthesis of # nutrient and sediment data for watersheds within the # Chesapeake Bay Drainage Basin, 1995, U.S. Geological Survey # Water-Resources Investigations Report 95-4233, p. 6. # # Contacts: Michael J.
