The name derives from the term " abyssal " identifies the seabed between 2000 m and 6000 m, and its use. It has the possibility of a sonar to map the ocean floor as well as to measure physical parameters of the water column by means of various sensors. It's run system with advanced lithium batteries. Dive time max Allow 22 hours.

Stock

As of March 2014, there are three copies of the type of which is at the Helmholtz Centre for Ocean Research ( GEOMAR) in Kiel, the other two are beimatet at the Woods Hole Oceanographic Institution in the USA.

Use

The AUV ABYSS is designed so that it can be used on all medium and large research vessels. Has been designed specially for the system, a special frame ( LARS), about the launching and recovery of the AUV over the stern or the side can take place.

All three AUV ABYSS came together in spring 2011 in the search for the wreckage of Air France flight 447 in the Atlantic Ocean are used.
