Global measurements of the Earth's magnetic field During the past 5 years the U.S. Geological Survey and Goddard Space Flight Center have cooperated in the analysis of presently available satellite magnetometer data. The principal objective of this project has been the identification of anomalies having geological significance. Additionally, these data are used in fulfilling Federal responsibility for supplying geomagnetic information for use in navigation, charting, and as a reference in geophysical prospecting. Even though the presently available satellite magnetometer data are not particularly suited for analysis of geological anomalies, the work done in this project indicates the potential for a satellite magnetometer as an effective geological/geophysical tool. A preliminary global magnetic anomaly map has been produced by analysis of existing satellite data (Regan and others, 1975). Verification of several distinct anomalies was obtained by examining detailed satellite data and by comparison with available aeromagnetic and geologic data. One of the most striking anomalies occurs in central Africa. This anomaly, termed the Bangui anomaly, was discovered by satellite and confirmed by aircraft measurements. A detailed interpretation of this anomaly indicates that it is caused by a massive, complex regional geological body that has several associated major mineral deposits.

TECHNOLOGY AND SYSTEM DEVELOPMENT, AS WELL AS BIOLOGICAL AND SG1177-7 Two AESOP's will be installed at high-elevation manned hydrometeorological data-collection sites. Data will be relayed via the GOES satellite and the existing high-speed data link between the World Weather Building in Suitland, Maryland, and the Bureau of Reclamation's Environmental Data Network computer in Denver, Colorado. A record will be maintained on all maintenance required during the test period, and the transmitted data will be compared with on-site data. Other uses of Data Collection Platforms are noted as follows: National Park Service is using the GOES system to monitor water quality and weather in the Great Smoky Mountains National Park. - GS Geologic Division is cooperating with NOAA in a study of the Earth's magnetic field. The GOES system is used to relay information from 25 strategically placed magnetometers to the NOAA facility at Boulder, Colorado, where quick access is available to researchers via computers. GS geologists are also using the GOES system to monitor variations in the abundance of helium in the soil in remote Nevada locations. The information is used in earthquake prediction research. The Bureau of Reclamation has also used a Data Collection Platform to monitor the spectral reflection of solar radiation from an irrigated corn field. Reflectance measurements are compared with measured plant conditions in the field. The demonstration could lead to new methods of irrigation management using remote sensing from space. A four-channel radiometer was mounted on a tower above the corn field to measure the reflected energy in each of the wavelength regions observed by Landsat. Data were relayed daily through the DCP. The data were then transmitted through land lines to the Bureau of Reclamation office in Denver, Colorado. There is a continuing need for a limited network of real-time surface weather observation stations on winter weather modification projects. Ground telemetry can be used but is very costly. Ground-based stations with the capability of frequent interrogation as offered by the GOES relay could prove to be an economical solution to the problem. An Automatic Environmental Surface Observation Platform (AESOP) was developed for the Bureau of Reclamation for use on the High Plains Cooperative Experiment. The first test of the AESOP is being made in the Sierra Nevada during the 1977-1978 winter season. The test is being conducted in the high-elevation mountain environment near Donner Pass. If data from the AESOP's compare favorably with data from gages presently located at the selected sites, the AESOP's may be moved to isolated sites without redundancy for the 1978-79 winter season. |
