Former Soviet Union (FSU) Gravity Data

Gridded gravity anomaly data for the Former Soviet Union (FSU) and Eastern Europe has been received by the National Geophysical Data Center(NGDC). The data file contains 1 x 1 degree grid data constructed from several one(1) degree latitude band files. The observed gravity values are believed to be referenced to the International Gravity Standardization Net 1971(IGSN71) and the gravity anomaly is believed to have been computed using the Geodetic Reference System 1967(GRS67) theoretical gravity formula.

Gravity Anomalies and Estimated Topography Derived from Satellite Altimetry

In many areas of the global ocean, the depth of the seafloor is not well known because survey lines by ships are hundreds of kilometers apart. Satellites carrying radar altimeters have measured the shape of the ocean along tracks only 3-4 km apart, and from these data we can make very accuratore (+/-3mGal) and high resolution (15km) maps of the marine gravity field. The gravity field mimics the seafloor topography in the 15-160 km wavelength band if sediment cover on the ocean floor is thin. Long-wavelength (greater than 160 km) topography is isostatically compensated and is not correlated with the gravity field. In addition, the satellite gravity field and the available depth measurements were used to determine the correlation between gravity and the seafloor topography. By applying this correlation to the gravity field we predict seafloor topography in the 15-160 km wavelength band. This topography is combined with a long-wavelength component estimated directly from ship depth measurements. The result reveals many new features and is within +/- 100m of actual depths in many cases. The Predicted Seafloor Topography derived from the depths estimated from Satellite Altimetry in combination with measured trackline bathymetry is an inferred data set and is not true bathymetry. It is, however, the best estimate of seafloor topography available resulting from satellite gravity data and actual ship depth measurements. These data are intended for scientific research and should not be used for navigational purposes. Additional software is required in order to manipulate the data or produce your own graphic images. Poster and CD-ROM products are available for both gravity anomaly and estimated seafloor topography of several regions.

Alaska1(ak1_wpn) Gravity Data

The gravity station data (10,578 records) were compiled by the U.S. Geological Survey and the State of Alaska Division of Geological & Geophysical Surveys. This data base was received in February, 1993. Principal gravity parameters include Free-air anomalies, isostatic anomalies and Simple Bouguer anomalies (no terrain correction applied). The "wpn" suffix indicates that a crustal thickness of 30 kilometers was used in the isostatic calculation. The observed gravity values are referenced to the International Gravity Standardization Net 1971 (IGSN 71). The gravity anomaly computation uses the Geodetic Reference System 1967 (GRS 67) theoretical gravity formula. Note that the original USGS Open File Report by D. F. Barnes mentions the use of the 1931 International Ellipsoid for gravity reduction but this is believed to have subsequently been changed to the GRS 67 system.

The Canadian Gravity Geoid

A detailed gravimetric geoid has been computed on a 10' by 10' grid for Canada by the University of New Brunswick. This data base was received in April 1989. Principal gravity parameters include latitude, east longitude, and total geoidial height above GRS'80 reference ellipsoid. The gravity data used for the spheroidal Stokes's integration consisted of point gravity anomalies for the innermost zone, of 5'x5' mean gravity anomalies for the inner zone, and 1x1 degree mean gravity anomalies for the outer zone. The gravity values are based on the International Gravity Standardization Net 1971 (IGSN71) and the reference ellipsoid 1980 (GRS80). For detailed documentation see Technical Report No. 129.

PR/VI East-West Deflections (DEFLEC96)

This 2' surface deflection of the vertical grid for Puerto Rico and the Virgin Islands is distributed as the DEFLEC96 model. The computation used about 26,000 terrestrial and marine gravity data held in the National Geodetic Survey gravity data base in July 1996. These data were augmented bygravity data contributions from NGA (former National Imagery and Mapping Agency) (formerDefense Mapping Agency).The deflections wereobtained by numerical differentiation of cubicspline models along the parallels of the GEOID96grid. The gravity values are based on theInternational Gravity Standardization Net 1971IGSN71). The deflections are referred to in theGeodetic Reference System 1980 (GRS80)ellipsoidal normals. The curvature of the plumbline correction has been applied. We areparticularly grateful to NGA (former National Imagery and Mapping Agency) for theirassistance and their data contributions.

Selected Geomagnetic Measurements From Several Satellites

More than 17 million selected magnetic observations from several orbiting low-altitude satellites are contained in this digital collection. Except for MAGSAT, all the observations are of total intensity (F) only. The MAGSAT data contain both scalar and vector X, Y, Z) values. MAGSAT was launched into a sun-lit, sun- synchronous orbit (350 to 550 km high) on October 30, 1979 with re- entry occurring on June 11, 1980. The MAGSAT data are being used for derivation of magnetic field models, magnetic field mapping, magnetic anomaly mapping, and inner earth studies. Twelve 9-track 1600 BPI, binary magnetic tapes {INV-B} cover a time span from November 2, 1979 to May 19, 1980. The data are organized by orbit number. Each data record contains 30 data points at approximately 5 second intervals. Additional magnetic tapes contain MAGSAT low- latitude scalar anomaly value data, gridded scalar anomaly data and Quiet Time data. In addition to the MAGSAT data, data from the OGO, Cosmos and Vanguard satellites are available. The POGS experiment magnetometer is of the same type that was designed and built by NASA for the Defense Meteorological Satellite Program (DMSP). The only modification to the design was to add extra thermal mass in order to reduce the magetometer's thermal drift to something less than 50 mT/goev. The U.S. Navy uses this satellite to update its World Magnetic Model (WMMxx).

Gravity Data for Indiana-over 10,000 records

The gravity data (10,629 records) were compiled by Purdue University. This data base was received in December 1989. Principal gravity parameters include Free-air Anomalies and Simple Bouguer Anomalies (no terrain correction applied). The observed gravity values are referenced to the International Gravity Standardization Net 1971 (IGSN 71). The gravity anomaly computation uses the Geodetic Reference System 1967 (GRS 67) theoretical gravity formula. The data are randomly distributed within the boundaries of central Indiana.
