Current Research Projects
We have conducting research on the biogeochemistry of carbon and nitrogen in the Sargasso Sea, the North Atlantic, the Ross Sea, the Indian Ocean, the eastern and western South Pacific, the Antarctic Polar Front, the Equatorial Pacific, and the Arctic Ocean. These efforts consist of both time series studies as well as survey and process work in various ocean basins.
Specific
studies focus on:
- Distribution
of DOM in the global ocean
- Carbon
dynamics at the shelf break in the
- Effect of
mesoscale eddies on the carbon cycle of the
- Time
series of dissolved organic carbon and nitrogen in the
- Carbon
export as DOC during North Pacific Intermediate Water formation
- Elevated
DOC and DON in the surface western tropical South Pacific.
- Carbon
transport in the meridionally overturning cell in the
- Time
series and spatial surveys of organic carbon in the
- Contribution
of DOC oxidation to AOU development in the main thermocline of the
western South Pacific.
- Net
community production of DOC.
- Carbon
cycling in the Equatorial Pacific.
- Deep ocean
gradients of dissolved organic carbon.
- Microbial
dynamics of DOC turnover
