Scott Wankel is an Associate Scientist in the Marine Chemistry and Geochemistry department at the Woods Hole Oceanographic Institution (WHOI). He received his PhD in stable isotope biogeochemistry from Stanford University, before extending his interests into the deep sea during his postdoc at Harvard University. At WHOI, his lab group’s research interests primarily focus on questions about the biogeochemical dynamics of elemental cycles, especially those of nitrogen, carbon and oxygen – often exploring how cycling of metals such as iron and manganese may also be tangled in these complex cycles. To better understand the underlying complexity of these cycles, his group employs a suite of approaches typically involving measurement of naturally occurring stable isotopes and/or development and deployment of in situ chemical and isotopic sensors for field based research. On this cruise, Scott serves as co-chief scientist with collaborator Anna Michel, and will be working to make chemical measurements of rising bubbles from the seafloor and to explore cryptic microbial metabolisms occurring in deep sea sediments.
