Magnetic Anomalies - an overview ScienceDirect Topics
Magnetic anomalies are generally a small fraction of the magnetic field. The total field ranges from 25,000 to 65,000 nanoteslas (nT). To measure anomalies, magnetometers need a sensitivity of 10 nT or less. There are three main types of magnetometer used to measure magnetic anomalies: The … See more 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 … See more Ground-based In ground-based surveys, measurements are made at a series of stations, typically 15 to 60 m apart. Usually a proton precession magnetometer is used and it is often mounted on a pole. Raising the magnetometer … See more Ocean floor stripes Magnetic surveys over the oceans have revealed a characteristic pattern of anomalies around … See more In the Space Odyssey series by Arthur C. Clarke, a series of monoliths are left by extraterrestrials for humans to find. One near the crater See more There are two main corrections that are needed for magnetic measurements. The first is removing short-term variations in the field from … See more Theoretical background The magnetization in the surveyed rock is the vector sum of induced and remanent magnetization: $${\displaystyle \mathbf {M} =\mathbf {M} _{\text{i}}+\mathbf {M} _{\text{r}}.}$$ The induced … See more • Bangui magnetic anomaly • Geomagnetic reversal • Kursk Magnetic Anomaly • Magnetic anomaly detector • South Atlantic Anomaly See more WebMagnetic anomaly detectors employed to detect submarines during World War II harnessed the fluxgate magnetometer, an inexpensive and easy to use technology developed in the 1930s by Victor Vacquier of Gulf Oil for … injection to build white blood cells
