Ocean Bottom Seismometer

An Ocean Bottom Seismometer (OBS) is a specialized device placed on the seafloor to measure ground vibrations caused by earthquakes, underwater volcanic activity, and other seismic events. It detects and records seismic waves that travel through the Earth's crust beneath the ocean, providing valuable data for understanding Earth's interior and tectonic processes. OBS units are typically equipped with sensors, a power source, and communication tools, and they either drift freely or are anchored to the seabed. After their deployment, they transmit the collected data to researchers for analysis, contributing to our knowledge of seismic activity under the oceans.
