Overview of Reseach Activities

Our main area of interest is the ocean's carbon cycle. As geochemists, we're interested on it's impact on 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 the ocean's carbon cycle change in response to increased CO2 in the atmosphere? How does the ocean naturally sequester carbon and how will this change in the future? How would we evaluate the feasibility, effectiveness and environmental consequences of purposeful ocean carbon sequestration as a strategy for managing levels of atmospheric CO2. Would such actions be 'safe'?

Experimental approaches to the problem include:
