Our main area of interest is the ocean’s carbon cycle. As geochemists, we’re interested in how carbon cycle processes influence the geochemical cycles of the 50 or so elements which exhibit nonconservative behavior in sea water (they don’t follow variations of sodium). Most of these elements are transported vertically in the ocean associated with particles of biogenic and terrestrial origin. As earth scientists, we’re concerned with the consequences of rising levels of CO2 in the atmosphere. How will living systems respond to climate induced change in the ocean? How does the ocean naturally sequester carbon and how will this change in the future? The research is multidisciplinary and requires knowledge of mathematics, chemistry, physics, biology, computer science, and engineering.
