ABSTRACT

Ocean-bottom seismometers are well-tested, functional tools commonly used in crustal seismology. They can be deployed much deeper and are more robust than ocean-bottom cables, being the only type of instrument for 4-C surveys at depths greater than 1500m. I present the state-of-the-art of the Japanese OBS technology and the logistics associated with it to the seismic industry reader.
