The Usage Of A New German Deep-Sea ROV (QUEST 5) And A Mobile Drilling System (BGS Rockdrill) For The Exploration Of Deep-Sea Mineral Deposits

The detailed investigation of both active and inactive submarine hydrothermal systems has gained tremendous progress during the last decades because of the increasing usage of remotely operated vehicles (ROV) as well as manned submersibles. Special aspects like the targeted sampling of chimney structures and vent fluids as well as the analysis of zonations of near-surface structures like sulfides mounds was only possible with the usage of such vehicles. However, the availability of such vehicles has been very limited because of the few number of deep-water ROVs and manned submersibles which need both a trained crew and a special research vessel. This was especially true for the German science community which did not have such devices at its disposal until recently. With the ROV QUEST 5 which is based at the University of Bremen (c/o. Prof. Dr. G. Wefer, Dr. V. Ratmeyer) this major drawback has now been eliminated.
