work in the air and now you want it to work in water and in this high-pressure environment,” Michel said. She is collaborating with Scott Wankel, an isotope biogeochemist at WHOI, to modify a laser Wankel originally developed during his postdoctoral research at Harvard with Peter Girguis to measure gases dissolved in fluids and bubbles under water. “What we analyze is a gas, so we need our samples to be in its gas form,” Wankel said. The device diffuses seawater through a Teflon membrane that extracts gas from the water. In gas form, the compounds absorb

vehicle for the first time after a major $42-million overhaul that dramatically upgraded the sub’s capabilities. “We’ve tested the core functions of the new Alvin, and we believe we have a great new tool for the scientific community,” said Harvard University scientist Peter Girguis. He was chief scientist of an expedition that ended March 26 in which scientists and pilots put the new sub through its paces in a series of dives under real field conditions. Their objectives were to assess the upgraded sub’s new capabilities, to learn how to use them to the best advantage
