Submarine Geodesy

Submarine geodesy is the science of measuring and mapping the shape, position, and movements of the Earth's underwater crust. It uses specialized tools, such as sonar and GPS, to determine the precise locations of underwater features like faults, trenches, and the seafloor itself. This information helps scientists understand tectonic processes, monitor earthquakes, and study sea level changes. Since measuring beneath the ocean surface is challenging due to water depth and pressure, submarine geodesy applies advanced technology to gather accurate data, crucial for both scientific research and hazard assessment.
