From the site: “The Geologic Atlas of the United States is a set of 227 folios published by the U.S. Geological Survey between 1894 and 1945. Each folio includes both topographic and geologic maps for each quad represented in that folio, as well as description of the basic and economic geology of the area. The Geologic Atlas collection is maintained by the Map & GIS Library. The repository interface with integrated Yahoo! Maps was developed by the Digital Initiatives -- Research & Technology group within the TAMU Libraries using the Manakin interface framework on top of the DSpace digital repository software.

Additional files of each map are available for download for use in GIS or Google Earth. A tutorial is provided which describes how to download theses files.”

Using a combination of public and proprietary historical construction test borings, recent exploration drilling, USGS observation wells, outcrops, and seismic measurements, a series of geospatial overlays for bedrock elevation and overburden thickness were created for the Five Boroughs of New York City, New York. Rasters were interpolated from a point elevation data set and refined using published and interpretive bedrock contours, and interpreted glacial valleys and faults. Contours for bedrock elevation were generated at 100-ft contour intervals and smoothed. This data release includes shapefiles containing the input point elevation features and output contours, and rasters of interpolated bedrock elevation and overburden thickness surfaces.

An increase in demand for New York State's groundwater resources has led to an increased need to develop groundwater protection and management policies. The aquifers represented in this theme resulted from an effort to facilitate the identification of the location and extent of significant unconsolidated aquifers; those that consist of sand and gravel and yield large supplies of water to wells. Bedrock aquifers, although significant in some areas, are not addressed here. The scale of the original aquifer maps is 1:250,000. That is also the scale of the published New York State Geological Survey surficial and bedrock geology maps on which they were based. Together these maps form a consistent set of geologic and groundwater maps for use in regional management of the groundwater resources of the State. These maps indicate only the general location of the unconsolidated aquifers; they are not intended for detailed site evaluations. Determination of the precise location of aquifer boundaries or of well yields may require additional data, according to authors of the source maps. These aquifers were digitized using a set of five 1:250,000 scale maps of unconsolidated New York State aquifers, excluding Long Island, originally created by the USGS in partnership with the NYSDEC in the mid 1980s.View Dataset on the Gateway

This data set includes topography and backscatter intensity of the sea floor of the Hudson Shelf Valley, located offshore of New York and New Jersey. The data were collected with a multibeam sea floor mapping system on surveys conducted November 23 - December 3, 1996, October 26 - November 11, 1998, and April 6 - 30, 2000. The surveys were conducted using a Simrad EM 1000 multibeam echo sounder mounted aboard the Canadian Hydrographic Service vessel Frederick G. Creed. This multibeam system utilizes 60 electronically aimed receive beams spaced at intervals of 2.5 degrees that insonify a strip of sea floor up to 7.5 times the water depth (swath width of 100 to 200 m within the survey area). Maps derived from the mulitbeam observations show sea floor topography, shaded relief, and backscatter intensity (a measure of sea floor texture and roughness). The data are gridded at 12 m/pixel. THIS DATA SET IS PRELIMINARY; PUBLICATION OF A FINAL DATA SET IS PLANNED IN 2003
