Caption

Vent fluid samples were collected using titanium isobaric gas-tight (IGT) samplers deployed by the remotely operated vehicle Jason aboard the R/V Atlantis in January 2012. The IGTs, unique instruments developed by Jeff Seewald and a team of WHOI engineers, are designed to maintain the sample fluid at the high pressure at which it was drawn.
