After 50 hours of shooting, we ´re started with the recovery of the OBH/S.
The first thing you have to do is to release the instrument that it can drop on the ocean surface.
Every instrument has a unique releaser code.
The GEOMAR OBH/S have a velocity of 60 meters per second, in water depths with more than 4000 meters, this may take a while…
Meanwhile the vessel is moving to the position of the instrument. From the bridge you can find the instrument when it´s on the surface easily (so far…).
And then the fishing starts …..
