Deep Sea Mining – Resources

I am concerned that beginning larger scale deep sea mining with current knowledge of the deep ocean and with current extractive technologies will be damaging to the health of the oceans and planet.

I recently looked at the types of extraction proposed, fearing that it might involve trawling or suction techniques, and it does appear to be based on such methods.

My own background is in AI and robotics, and I had hoped that if anything was to be approved in the near future that rather than using large scale seabed “hoover” polymetallic nodule gathering machines damaging the deep ocean bed and its occupants, the process might involve the development of potentially gentle approaches which could use AI, vision and robotic picker arms. Almost like a scuba diver floating over, leaving items that are associated with wildlife and only picking appropriate useful items without sea bed damage.

Can I ask that the UK adopts a position of asking for a pause on deep sea mining as that would allow for consideration of the impacts, a better understandings of the deep sea and the development of advanced gentle extraction techniques in research areas before any larger scale extraction was permitted.

I hope the UK government will support this approach.
