Preliminary results of research at the active summit of Mt. Wrangell, Alaska (Abstract). The geothermal heat flux has increased Significanty at the summit of Mt. Wrangell since 1964. This has I resulted in melting over 22 million m3 of' ice from the North Crater of the summit caldera, an order of magnitude increase in the area of exposed rock, and a settling of the glacier surface of up to 160m. Field work at the summit in August 1975, included establistment or five ground control points for aerial photogrammetry , measurement of glacier flow and resurvey of the snow surface in the caldera and North Crater, measurement of temperatures and temoerature gradients in exposed ash and sand, and two 4m glaciological oit studies with cores extending below 10 m. Nearly continuous air temperature, wind, atmospheric pressure, and seismic data were obtained over a three week oeriod. Preliminary analysis of glacier flow data indicate an apparent increase in glacier velocity since 1965. Glaciological volcanological studies at the summit began in 1961.
Report by the geothermal program at the Applied Physics Laboratory of Johns Hopkins University to help determine whether geothermal energy from a shallow (3,000 ft.) well could be used for supplementing heating requirements at the Dover Air Force Base located in Dover, Delaware
Progress report on the geothermal potential for southern Delaware by focusing on the inclusion of additional gravity mapping, contouring gravity data, and some preliminary quantitative interpretations of gravity and magnetic data
The Gravity Map of Delaware and Surrounding Vicinity in Maryland and Virginia illustrates contoured gravity values for Delaware and parts of the adjacent vicinities of Maryland and Virginia. The map is georeferenced, but no legend is included. The gravity map is available for direct download as a PDF file through Virginia Tech. The document was provided by the Virginia Department of Mines, Minerals, and Energy - Division of Geology and Mineral Resources and made available for distribution through the National Geothermal Data System.
This resource is a compilation of well log observation data for Delaware water wells and oil and gas wells and provides links to representations of the actual geophysical well log , which typically will be either a paper copy, scanned image, or LAS file. These data were compiled by the Virginia Department of Mines, Minerals, and Energy, Division of Geology and Mineral Resources and the Delaware Geological Survey and are available in the following formats: web feature service, web map service, ESRI service endpoint, and an Excel workbook for download. The workbook contains 5 worksheets, including information about the template, resource provider information, the data, a field list (data mapping view). and a worksheet with log type codes. This resource was provided by the Delaware Geological Survey and made available for distribution through the National Geothermal Data System.
Report of investigations analyses of drillers' and geophysical logs, cuttings, and 29 core samples from well Nc13-3 near Greenwood, Sussex County, Delaware indicate that the l500-foot section penetrated by the drill can be divided into seven rock-stratigraphic units: Matawan Formation, Monmouth Formation, unit A, Piney Point Formation, Chesapeake Group (undifferentiated), Staytonville unit, and the Columbia Formation. The rock units are identified on the basis of texture, mineralogy, color, and interpretation of electric and gamma-ray logs. The oldest rocks penetrated are Upper Cretaceous; Tertiary and Quaternary rocks were also encountered.
This resource is a compilation of borehole temperature observation data from water wells provided by the Virginia Department of Mines, Minerals and Energy, Division of Geology and Mineral Resources and Delaware Geological Survey. These data are published as a Web feature service and available in the following formats: web feature service, web map service, ESRI service endpoint, and an Excel workbook for download. The workbook contains 4 worksheets, including information about the template with notes related to revisions of the template, resource provider information, the data, and a field list (to assist data mapping). This resource was provided by the Delaware Geological Survey and made available for distribution through the National Geothermal Data System.
This resource is a compilation of the Geologic Units of Delaware, provided by the Delaware Geological Survey and made available for distribution through the AASG Geothermal Data Systems project, published as a web feature and available as an Excel workbook for download. The workbook contains 7 worksheets, including information about the template, notes related to revisions of the template, Resource provider information, the data, a field list (data mapping view) and vocabularies used to populate the data worksheet (data valid terms). Data from 54 geologic units are included. Fields in the data table include unit names, descriptions, symbols/labels, lithology and data source.

This map shows the surficial geology of New Castle County, Delaware, at a scale of 1:100,000. Maps at this scale are useful for viewing general geologic framework on a county-wide basis, determining the geology of watersheds, and recognizing the relationship of geology to regional or county-wide environmental or land-use issues. The map was compiled from topographic and geologic maps, aerial photographs, geologists' and drillers' logs, geophysical logs, soils maps, and sample descriptions. Samples from drill holes and outcrops were examined for comparison with previous descriptions. Other than the Old College (Ramsey, 2005) and Bridgeton Formations (Owens, 1999; Owens et al., 1970), all geologic units were previously mapped or described in Delaware. Descriptions of geologic units, unless otherwise referenced, were generated by the author after examination of cores, outcrops, and samples from the Delaware Geological Survey Core and Sample Repository.
