What did the Aegir 6000 remotely operated mission achieve?

Question

Accepted Answer

The Aegir 6000 remotely operated mission successfully filmed the wreck of the Komsomolets submarine and collected samples that revealed significantly elevated radioactivity levels.

The expedition marked the first use of the Aegir 6000 remotely operated vehicle (ROV) during a monitoring mission for the Soviet nuclear submarine Komsomolets, which sank in the Norwegian Sea in 1989. The ROV was employed to capture footage of the submarine's wreckage and to retrieve samples from the seabed surrounding the site.
Filming of the Submarine Wreckage

During the expedition, the Aegir 6000 was instrumental in visually documenting the state of the Komsomolets wreck. This allowed researchers to observe the condition of the submarine at a depth of approximately 1,700 metres. Previous monitoring efforts, which have been conducted annually since the 1990s, had not utilised such advanced remote imaging technology.
Collection of Radioactive Samples

The samples collected by the Aegir 6000 provided crucial data on the environmental conditions around the sunken submarine. Analysis of these samples indicated radioactivity levels at the site that were found to be up to 800,000 times higher than normal. This finding was communicated by the Norwegian Radiation and Nuclear Safety Authority.
Context of Radiation Levels

Despite the exceptionally high measured radioactivity, expedition leader Hilde Elise Heldal of the Norwegian Institute of Marine Research stated that the levels found were not alarming. She explained that radioactivity disperses rapidly at such depths and that the immediate area around the wreck has limited marine life, mitigating potential risks. The Komsomolets submarine sank on April 7, 1989, following a fire onboard that resulted in the deaths of 42 crew members.
