The Golovko was accompanied by oceanographic research vessel Yantar and supporting tanker Vyazma.

The US National Oceanographic and Atmospheric Administration has warned that this seabed mining could “result in the destruction of life and the seabed habitat in the mined areas”.

To overcome these challenges, Brianna Garcia, Amy Apprill, Elizabeth Kujawinski and colleagues at Woods Hole Oceanographic Institution tested a technique that modified the dissolved metabolites before they were extracted from seawater into a form that's compatible with membrane materials allowing them to be concentrated and analyzed.

Built in the wake of the Nereus disaster, the new devices are designed to be relatively cheap to replace, much like small “cube satellites” now orbiting Earth by the hundreds, explains Tim Shank, a deep-sea biologist at the Woods Hole Oceanographic Institution, which operates Alvin for the U.S.

"This climatological anomaly and associated oceanographic changes may have played a similar role in shifting cownose rays eastward from their established range to Bermuda," said Ajemian.
