Phoenix mobilized their 6,000 meter depth-rated Remora III ROV aboard the Chinese Rescue Salvage Bureau (RSB) vessel Dong Hai Jiu 101 in support of the on-going deep ocean search. Phoenix has been involved in the search for MH370 since April 2014, initially using their 5,000 meter depth-rated Autonomous Underwater Vehicle (AUV) “Artemis,” and Hydrospheric Solutions Inc. 6,000 meter depth-rated ProSAS-60 towed synthetic aperture sonar system. The MH370 international search team, under the leadership of the ATSB, has searched more than 110,000 km2 of seafloor.
