The OBS labs at LDEO, SIO and WHOI design, build, maintain and operate the entire fleet of instruments that form the Ocean Bottom Seismograph Instrument Pool.
The instruments that comprise the pool are generally configured for either short or long period deployment experiments. Short period instruments are primarily designed for use in experiments involving an active source (e.g. air-guns) or passive listening at frequencies greater than 1 Hz. Long period instruments have been designed for extended-length deployments which record low frequency (<1 Hz) seismic energy from a passive source (e.g. earthquakes). However, instruments within the pool are not confined to a particular type of experiment and, subject to availability, can be used for any field program envisioned.
