Summary of Field Work: |
Assessing the role of vitamin B12 and nitrogen availability on the regulation of oceanic dimethylsulfoniopropionate (DMSP) and dimethylsulfide (DMS).
A series of 8 expeditions over 2 calender years (4 per year) would examine the seasonal and spatial variability of vitamin B12 concentrations and its impact on DMS and DMSP degradation in the South Atlantic Bight near Savannah, Georgia. During each 6-day expedition, hydrographic and DMS profiles would be collected along an approximately 400 nautical mile transect running from the inner continental shelf out to the Sargasso Sea. Based on the results of this survey, two stations would be selected and occupied for 12-24 hours to carry out more intensive metatranscriptomc and metaproteomics sampling of the phytoplankton and bacterial communities. Ideally, the expeditions in each year will be scheduled to coincide with the timing of key events (based on currently known hydrographic and B12 data):
1) mid-March - winter temperature minimum/B12 maximum
2) mid-May - spring warming
3) late July - summer temperature maximum/B12 minimum
4) late September - autumn cooling. |
