What is marine magnetometry?
Marine magnetometry is the measurement of Earth’s magnetic field over oceans to study seafloor geology, crustal structure, and magnetic anomalies.
What will I learn in an Introduction to Marine Magnetometry course?
You will learn magnetic-field fundamentals, survey instruments, data acquisition, anomaly interpretation, and common marine applications.
How is marine magnetic data collected?
Data are commonly collected with a magnetometer towed behind a vessel or mounted on an autonomous underwater vehicle, along planned survey lines.
What is a marine magnetic anomaly?
A marine magnetic anomaly is a local difference from the expected magnetic field, often caused by variations in magnetized rocks beneath the seafloor.
Why is marine magnetometry important for seafloor mapping?
It helps identify geologic boundaries, volcanic features, faults, sedimentary basins, and patterns of oceanic crust formation.
What instruments are used in marine magnetometry?
Common instruments include proton-precession, optically pumped, and Overhauser magnetometers, often supported by GPS and motion sensors.
Can marine magnetometry be used to study plate tectonics?
Yes. Magnetic stripe patterns on the ocean floor provide evidence of seafloor spreading and help reconstruct plate motions and geomagnetic reversals.
