Longterm OBS for Tsunami and Earthquake Research

The titanium frame LOBSTER is a Broadband-OBS- System, designed and manufactured for the Alfred- Wegener-Institute for Polar and Marine Research in Bremerhaven / Germany.

It is the instrument carrier for broadband seismometer, recorder, releaser and batteries each in a titanium pressure tube as well as for float units made of syntactic foam.

Buoyancy and anchor are asymmetrically designed: the instrument ascends in vertical position to the water surface whereas it descends to the seafloor and stays there for data recording in horizontal position.
