Hi Tracey,
The specimens were collected using a Remotely Operated Vehicle operated by the British Antarctic Survey. So, observed via video and then collected with some collection arm or other similar device. Water temp in this area was variable. "Background" was below freezing (-1.5C) whereas the vent itself was almost 400 C (380 degrees). The stars were collected in a zone intermediate, so about 9-15 degrees or so? Temps were variable.

Fascinating find! I have two questions - how were the specimens found and collected? And what was the temperature of the water at each collection site (in celsius is good)?
Thanks!
