Much has been speculated on the impact of industrial deep-sea mining on marine ecosystems. This study led by @evastewart.bsky.social provides some direct empirical evidence.

Selection of images of Paulasterias mcclaini, an orange starfish with six arms, including scanning electron microscope images of pedicellaria

New paper! We report the first confirmed Atlantic record of the very cool starfish family Paulasteriidae from an inactive sulphide area on the Mid-Atlantic Ridge, collected as part of the ULTRA project at @noc.ac.uk

Spiky Sea Urchin on Ahyi Seamount | Nautilus Live YouTube video by EVNautilus

While exploring Ahyi Seamount, the team spotted this Diadema setosum #urchin nestled in an algae bed around 74 meters deep. These #marineinvertebrates are known for their extremely long, black, hollow spines interspersed with stinging, pincher-like pedicellariae.

Paper out today from the #NHMDeepSea team on these strange little worms from the abyss. First of 3 highly technical papers on them, possibly not headline-makers but science is all in the detail. www.sciencedirect.com/science/arti...

Long-term impact and biological recovery in a deep-sea mining track - Nature Nature - Long-term impact and biological recovery in a deep-sea mining track

A great paper, albeit with a bleak message, that recovery in the deep sea, if possible at all, will occur on decadal to century scales. #deepsea #marinelife #science www.nature.com/articles/s41...
