ISBN: 0607866365
Original factory shrink wrapper. ; Hard plastic case with covers. This publication consists of a report presented in Acrobat PDF format (560 KB) , a large gravity-station-location map (PDF; 3.1 MB) , and a data directory (12 MB). Gravity data for the entire state of Nevada and adjacent parts of California, Utah, and Arizona are available on CD-ROM (see "Availability" below) and on this Web site (see Data Files, below). About 80,000 gravity stations were compiled primarily from the National Geophysical Data Center and the U. S. Geological Survey. Gravity data were reduced to the Geodetic Reference System of 1967 and adjusted to the International Gravity Standardization Net 1971 gravity datum. Data were processed to complete Bouguer and isostatic gravity anomalies by applying standard gravity corrections including terrain corrections and isostatic corrections. A 1_README. TXT (see below) file describes the contents of the CD-ROM and includes a description of the data reduction process, selected principal fact references, and a list of sources for data from the National Geophysical Data Center. ; U. S. Geological Survey Digital Data Series DDS-42; 5.60 X 4.80 X 0.40 inches.
