| Abstract |
We relate about the custom-made modification of a Benthos deep-ocean acousticrelease into a ‘deep caller’, a hydrophone for calling ocean acoustic releases that cannotbe reached from a standard deck-unit. The self-contained deep caller can be lowereddown to 12 km on any non-conducting winch cable. It may prove useful to retrieve subsurface instrumentation like a seafloor-lander hidden behind large rocks or in a narrowcanyon, or moorings in very deep topographic depressions. We used it to retrieve a 7km long mooring from 10,910 m depth in the Challenger Deep, Mariana Trench. |
