Biogeochemical cycling of the major elements (carbon, nitrogen, etc.), particularly through dissolved organic matter (DOM). Open ocean and polar seas; times series, ocean sections, and process studies. Air-sea interactions; biogeochemical processes of both surface and deep ocean waters.
We focus primarily on carbon and nitrogen cycles and the distribution and movement of dissolved organic matter (DOM) in the ocean. These efforts consist of both time series studies as well as survey and process work in various ocean basins.

Organic Biogeochemistry Laboratory focuses primarily on carbon and nitrogen cycles and the distribution and movement of dissolved organic matter (DOM) in the ocean. These efforts consist of both time series studies as well as survey and process work in various ocean basins.
Chemistry Laboratory The analytical instruments in the chemistry lab allow for quantifying the following parameters: 1) inorganic nitrogen, phosphate, and silicate; 2) dissolved organic carbon and nitrogen; 3) trace elements and their stable isotopes; 4) carbonate species; 5) alkalinity, salinity and pH; 6) density; 7) tritium, CFCs, SF6.
