I am a PhD candidate in the Massachusetts Institute of Technology-Woods Hole Oceanographic Joint Program in Chemical Oceanography, where I study the organic, inorganic and volatile chemistry of deep-sea hydrothermal vent fluids. I am particularly interested in carbon system reactions in ultraslow-spreading hydrothermal systems, and the effect of great depth on the transport of metals, organic species, and gases. During this cruise I will be measuring dissolved gases in the water column, to help pinpoint the location of as-yet unknown vent fields. Then I will be collecting and performing chemical analyses on deep sea vent fluids. These observations will help constrain the relative importance of abiotic versus biological carbon sources to vent fluids at the Mid-Cayman Rise, and the impact of venting on microbial communities.
