1994 MARYLAND BIOLOGICAL STREAM SITE LOCATION (SITE94)

Description:
The Maryland Biological Stream Survey (MBSS) is a multi-year probability-based sampling program designed to assess the status of biological resources in non-tidal streams of Maryland. The MBSS study area comprises eighteen drainage basins across the state of Maryland, providing biological, water chemistry, and physical habitat data for approximately 300 first- through third-order stream sites per year. During 1994, the program conducted a Demonstration Project to test field protocols and refine the sampling design prior to full implementation of the MBSS during 1995-1997. Sampling for the 1994 Demonstration Project was conducted in seven basins: Youghiogheny, Potomac-Washington Metro, Patuxent, West Chesapeake, Susquehanna, Choptank, and Pocomoke. The SITE94 data set contains information describing the location of each site at which samples were collected during the MBSS 1994 Demonstration Project. This information includes spatial coordinates and other site descriptors including the basin, county, physiographic province, stream reach, stream order, sampleability and site type with respect to the study design. Variables in this data set are useful in sorting, stratifying, or otherwise interpreting the other MBSS 1994 data sets.
