First day of actual mission on the field, under the kronebreen glacier, in kongsfjord in svalbard. The purpose of the mission is to take samples of water and to acquire environmental parameters near the glacier, an area that for safety reasons is forbidden to navigation. We were surprised by a sudden strong wind that trapped proteus in an ice grip. We have therefore been forced to cut the safety cable linking the vehicle to the support vessel and to implement a risky recovery operation. Fortunately, with the help of the aircraft drone, we were able to pinpoint the location of the vehicle and then retrieve it. Hope it’s better tomorrow.
