Preliminary integrated geologic map databases for the United States: Minnesota, Wisconsin, Michigan, Illinois, and Indiana Preliminary integrated geologic map databases for the United States: Minnesota, Wisconsin, Michigan, Illinois, and Indiana
The growth in the use of Geographic Information Systems (GIS) has highlighted the need for regional and national digital geologic maps attributed with age and lithology information. Such maps can be conveniently used to generate derivative maps for purposes including mineral-resource assessment, metallogenic studies, tectonic studies, and environmental research. This Open-File Report is...

Principal facts for gravity data collected in Wisconsin: A web site and CD-ROM for distribution of data Principal facts for gravity data collected in Wisconsin: A web site and CD-ROM for distribution of data
Principal facts for 40,488 gravity stations covering the entire state of Wisconsin are presented here in digital form. This is a compilation of previously published data collected between 1948 and 1992 from numerous sources, along with over 10,000 new gravity stations collected by the USGS since 1999. Also included are 550 gravity stations from previously unpublished sources. Observed...

Ecosystem history of southern and central Biscayne Bay: Summary report on sediment core analyses - year two Ecosystem history of southern and central Biscayne Bay: Summary report on sediment core analyses - year two
The Comprehensive Everglades Restoration Plan (CERP) lists restoration of the timing, quantity, and quality of the natural flow of freshwater as one its primary goals. Before restoration can occur, however, the baseline conditions of the environment prior to significant human alteration must be established and the range of variation within the natural system must be determined. In...

Proceedings of the twentieth annual meeting of the Society for Organic Petrology Proceedings of the twentieth annual meeting of the Society for Organic Petrology
The Society for Organic Petrology (TSOP; pronounced "Tee'-sop") was established in 1984 to consolidate and foster the organizational activities of scientists and engineers involved with coal petrology, kerogen petrology, organic geochemistry, and related disciplines. The following report, "Proceedings of the Twentieth Annual Meeting of The Society for Organic Petrology" (ISSN 1060-7250)...

Water-quality synoptic sampling, July 1999: North Fork Shenandoah River, Virginia Water-quality synoptic sampling, July 1999: North Fork Shenandoah River, Virginia
A study was conducted of water-quality conditions that may affect aquatic life during periods of low streamflow on the North Fork Shenandoah River, Va. Monthly mean streamflows in July 1999 at three streamflow-gaging stations were the lowest measured during the historical record on the river. Daily extremes of dissolved-oxygen concentrations were measured, along with pH, specific...

New seafloor map of the Puerto Rico Trench helps assess earthquake and tsunami hazards New seafloor map of the Puerto Rico Trench helps assess earthquake and tsunami hazards
The Puerto Rico Trench, the deepest part of the Atlantic Ocean, is located where the North American (NOAM) plate is subducting under the Caribbean plate (Figure l). The trench region may pose significant seismic and tsunami hazards to Puerto Rico and the U.S.Virgin Islands, where 4 million U.S. citizens reside. Widespread damage in Puerto Rico and Hispaniola from an earthquake in 1787...

Sediment dynamics in the Adriatic Sea investigated with coupled models Sediment dynamics in the Adriatic Sea investigated with coupled models
Several large research programs focused on the Adriatic Sea in winter 2002-2003, making it an exciting place for sediment dynamics modelers (Figure 1). Investigations of atmospheric forcing and oceanic response (including wave generation and propagation, water-mass formation, stratification, and circulation), suspended material, bottom boundary layer dynamics, bottom sediment, and small...

Integrating digital information for coastal and marine sciences Integrating digital information for coastal and marine sciences
A pilot distributed geolibrary, the Marine Realms Information Bank (MRIB), was developed by the U.S. Geological Survey Coastal and Marine Geology Program and the Woods Hole Oceanographic Institution, to classify, integrate, and facilitate access to scientific information about oceans, coasts, and lakes. The MRIB is composed of a categorization scheme, a metadata database, and a...
