From page 208... ...
The most recent satellite to have done this was Magsat, 12 years ago. Despite considerable efforts during the intervening time, no subsequent geomagnetic satellite mission has been carried out.

From page 209... ...
The measurement of magnetic fields from satellites is driven by basic scientific needs; NASA has developed a competent group of scientists engaged in the study of the magnetic field of the Earth, from core field modelers to crustal anomaly experts. Major advances have been made in the ability to analyze noisy satellite data, to produce the most accurate magnetic field mode!

From page 210... ...
Because of the major role that USGS plays in understanding the crustal geology of the United States, there is considerable emphasis on the collection and analysis of crustal geomagnetic field anomalies both on {and and over areas of the exclusive economic zone. The USGS conducts low-altitude aeromagnetic studies for mineral and energy assessment, earthquake, and volcanic hazard studies, and a variety of other USGS missions.

From page 211... ...
There is still interest in USGS in obtaining a more detailed crustal anomaly data base by flying a satellite in a lower orbit than Magsat. The USGS can support and coordinate multiagency acquisition of new aeromagnetic data in the United States by use of improved data-merging techniques and by use of USGS geophysical aircraft.

One important NOAA mission is to monitor geomagnetic field activity. Jointly with the Air Force Air Weather Service, NOAA operates the Space Environment Services Center, which is staffed 24 hours a day.

From page 213... ...
DMA products include a world magnetic field model, compass roses on maps and charts, world geophysical data charts, and magnetic anomaly detection charts (cIassified)

From page 214... ...
Of these, one of the most important is Project Magnet. This aircraft program collects magnetic field data worldwide using advanced scalar and vector magnetometers.

From page 215... ...
In addition, there is much work on tectonic problems and, although there is not much support for the analysis of lithospheric magnetic anomalies except in oceanic areas, the overall crustal program within NSF provides important constraints for lithospheric models of magnetic anomalies. There is also some support for electromagnetic studies, both of deep Earth and crystal conductivity.

From page 216... ...
Appropriate agencies could fund student stipends and expenses through university grants or contracts. Since the number of women and minorities entering professional science careers is still small, special encouragement should be given to these groups.

From page 217... ...
The effective warning of geomagnetic storms would have immense monetary benefits to the country, and the data obtained would help improve the understanding of the external magnetic field of Earth and so provide a better internal field model. These steps should be taken jointly by NASA, NOAA, DOE, and DOD.
|
From page 218... ...
Coordination of these geophysical observatories should involve NSF, NOAA, USGS, NASA, DOD, and other relevant federal agencies. The antarctic geomagnetic observatories financed by the NSF Division of Polar Programs should be converted into absolute instruments with help from the USGS.
