The World Digital Magnetic Anomaly Map (WDMAM) was first made available by the Commission for the Geological Map of the World in 2007. Compiled with data from governments and institutes, [1] the project was coordinated by the International Association of Geomagnetism and Aeronomy, and was presented by Mike Purucker of NASA and Colin Reeves of the Netherlands.

In geophysics, a magnetic anomaly is a local variation in the Earth's magnetic field resulting from variations in the chemistry or magnetism of the rocks. Mapping of variation over an area is valuable in detecting structures obscured by overlying material. The magnetic variation (geomagnetic reversals) in successive bands of ocean floor ...
The magnetic anomaly from a submarine is usually very small. One source estimates that it is only about 0.2 nT at a distance of 600 m. [5] Another source estimates that a 100 m long and 10 m wide submarine would produce a magnetic flux of 13.33 nT at 500 m, 1.65 nT at 1 km and 0.01 nT at 5 km. [6] To reduce interference from electrical equipment or metal in the fuselage of the aircraft, the ...

Magsat. Magsat (Magnetic field Satellite, Applications Explorer Mission-C or AEM-C or Explorer 61) was a NASA / USGS (United States Geological Survey) spacecraft, launched on 30 October 1979. The mission was to map the Earth's magnetic field, the satellite had two magnetometers. The scalar (Cesium vapor) and vector magnetometers gave Magsat a ...
Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind. This is a stream of charged particles leaving the Sun's corona and accelerating to a speed of 200 to 1000 kilometres per second. They carry with them a magnetic field, the interplanetary magnetic field (IMF).
The Stokes Magnetic Anomaly has been characterised for over 3,000 km (1,900 mi) and was essential for understanding the geology of Zealandia as a mainly underwater continent. It extends from 700 km (430 mi) south of New Caledonia to almost the eastern edge of the Campbell Plateau. [5] Over much of its length it has peaks about 30 km (19 mi) to ...
She led projects involving compilations of large geophysical datasets including the Circum-Arctic Mapping Project part (CAMP-GM) of the new World Digital Magnetic Anomaly Map release (WDMAM). Previously Carmen was the team leader of the Centre for Geodynamics, Norwegian Geological Survey in Trondheim, Norway.
