Who You Gonna Call?

Associate Scientist Jeff Seewald and his vent-sampling team (Joint Program student Eoghan Reeves, kneeling in front, and behind from left are Peter Saccocia, associate professor of Earth Sciences at Bridgewater State College, WHOI Assistant Scientist Olivier Rouxel, Seewald, and Bridgewater State College student Emily Walsh) line up on the R/V Melville, with everyone holding purpose-built titanium fluid samplers. The group spent a month in the eastern Manus Basin, near Papua New Guinea in 2006, collecting hydrothermal vent fluids to analyze their composition. At this site, a back-arc spreading center, the fluids were so acidic that they required titanium containers. (Photo by Paul Craddock, Woods Hole Oceanographic Institution)
