Toward digital geologic map standards: a progress report
Establishing modern scientific and technical standards for geologic maps and their derivative map products is vital to both producers and users of such maps as we move into an age of digital cartography. Application of earth-science data in complex geographic information systems, acceleration of geologic map production, and reduction of population costs require that national standards be developed

Two-dimensional circulation modeling of the Pamlico River estuary, North Carolina
A two dimensional, vertically averaged, unsteady flow model was applied to a 50- kilometer reach of the Pamlico River estuary, North Carolina. The model computational grid, which consists of about 16,000 square cells, each 200 meters on a side, was developed from more than one million depth soundings. Information from a comprehensive data-collection network, including six water-level stations, six

Using soil gas radon and geology to estimate regional radon potential
Two important parameters have been identified in order to estimate the radon potential of a region. They are the soil gas radon concentration and the geological rock type from which soils are derived. A simple soil gas collection and analytical technique has been developed to provide information on soil gas radon concentrations. The application of these techniques has demonstrated a clear relation

USFWS selected geographic analyses
The geographic information system (GIS) used by the National Wetlands Research Center (NWRC) of the U.S. Fish and Wildlife Service has been valuable in assisting natural resource managers in planning and managing coastal fish and wildlife resources. In the past 5 years, NWRC has conducted about 60 studies employing this technology. Applications have ranged from simple natural resource inventories
