  • Gravity Gradiometry Lockheed Martin

    Gravity Gradiometer technology measures minute differences in the earths density to yield information on geologic structures underground and undersea. This information is used for a variety of applications, including natural resource exploration, navigation, and underground detection and can be deployed on marine ships and aircraft.

  • Little Giant Magnetic Drive Pumps Water Pump Supply

    Magnetic Drive Pumps. Little Giant magnetic drive pumps eliminate seal caused friction loss, contamination and leakage. Drive magnet is separated from impeller magnet, preventing fluid from contacting the motor drive shaft, and allowing the motor to drive the impeller without a mechanical seal.

  • Geophysical survey

    Geophysical survey is the systematic collection of geophysical data for spatial studies. Detection and analysis of the geophysical signals forms the core of Geophysical signal processing. The magnetic and gravitational fields emanating from the Earth's interior hold essential information concerning seismic activities and the internal structure.

  • Magnetic and Gravity Methods in Mineral Exploration the

    Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.
