During Dive 18 of the 2021 North Atlantic Stepping Stones expedition, we observed more than five rare rock pens, despite being on the seafloor for less than an hour. It has been confirmed that these observations, made at a depth of 3,790 meters (12,434 feet) depth, represent the deepest-known record for rock pens in the Atlantic. The rock pens were also an unknown species, though unfortunately we were not able to collect one for further analysis.
