marine magnetic surveys

Marine magnetic surveys are techniques used to map variations in the Earth’s magnetic field beneath the ocean's surface. By towing sensitive magnetometers behind ships, scientists detect differences in magnetic strength caused by underground rock formations. These variations help identify structures like underwater volcanoes, faults, or mineral deposits, providing valuable information for geoscience research, resource exploration, and understanding tectonic processes. The data collected is processed and analyzed to create detailed magnetic maps of the seafloor, offering insights into the Earth's subsurface characteristics in marine environments.
