A marine magnetic survey is the measurement of Earth's magnetic field intensity or its components (such as vertical component) along a series of profiles over an area of interest with the objective of measuring the magnetism of the ocean floor. The seafloor is known to be highly magnetized in a pattern of magnetic stripes that record the history of Earth's magnetic field behavior, which in turn, allows marine scientists to determine the age and history of seafloor spreading in the ocean basins (see  Vine‐Matthews‐Morley hypothesis). Magnetic surveys are also used to locate a concentration or absence of magnetic minerals in the search for economic ore deposits (Sheriff, 1981). Variations in the observed magnetic field from the predicted regional field are called magnetic anomalies and are attributed to variations in the distribution of materials having different magnetic polarity, remanent magnetization, and/or susceptibility. The SI units of measurement for Earth's magnetic...
