The AUV Abyss is an underwater vehicle built in Pocasset / Massachusetts by the US company Hydroid for ocean research. AUV stands for Autonomous Underwater Vehicle . The name is derived from the term " Abyssal ", which describes the seabed between 2000 m and 6000 m, and its place of use. It has the option of mapping the sea floor using an echo sounder and of measuring physical parameters of the water column using various sensors. The system is operated with state-of-the-art lithium batteries , which have a diving time of max. Allow 22 hours.

Current equipment

  • a conductivity, temperature and pressure probe (CTD)
  • a particle sensor
  • a high-resolution fan echo sounder
  • a side viewing sonar
  • a sonar that creates depth profiles of the sediment
  • a photo camera for mapping and documenting the seabed

Duration

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

commitment

The AUV Abyss is designed so that it can be used on all medium-sized and large research vessels. A special frame (LARS) was specially designed for the system, via which the AUV can be deployed and retrieved from the stern of the ship or the side.

All three AUV Abyss were used together in the spring of 2011 in the search for the wreck of Air France Flight 447 in the Atlantic.
