1997, Conference Paper, Expanding sediment research capabilities in today's USGS: proceedings of the U.S. Geological Survey (USGS) Sediment Workshop
For more than a century the USGS, as its name implies, has been the leading federal earth science research organization for the Nation. With the recent addition to the USGS of the National Biological Service in October 1996, as the Biological Resources Division, the mission of the USGS has broadened...
Pesticides in ground water: distribution, trends, and governing factors
Jack Barbash, Elizabeth A. Resek
1997, Book
A comprehensive review of published information on the distribution and behavior of pesticides and their transformation products in ground water indicates that pesticides from every chemical class have been detected in ground waters of the United States. Many of these compounds are commonly present at low concentrations in ground water...
Early vegetational changes on a forested wetland constructed for mitigation
Matthew C. Perry, P.C. Osenton, C.B. Sibrel
1997, Wetland Journal (9) 17-20
Changes in vegetation were studied on 15 acres of a 35 acre forested wetland created as a mitigation site in Anne Arundel County, Maryland during 1994-96. Meter-square sampling on four different hydrologic elevations determined that grasses initially dominated the area, but decreased from 59 percent in 1994 to 51...
Development of an IBI-based assessment of depressional wetlands in Maryland and Delaware
D. W. Sparling, Michael Keller, T. P. Lowe, M. Perry, B. Teels, L. Brown, L. Mazanti, N. Melvin
1997, Book chapter, The Future of Wetland Assessment: Applying science through the hydrogeomorphic assessment approach and other approaches. Abstracts of a meeting held March 10-13, 1997, Parole, Maryland.
The hydrogeomorphic approach (HGM) of wetland assessment emphasizes functional components of wetlands such as water storage, transformation and cycling of elements, accumulation of sediments, and preservation of habitats. Many of the elements measured in HGM are physical rather than ecological or biological. The HGM approach, therefore, provides information on...
