Summary of Field Work: |
We propose to collect water for DOC/DIC analysis and optical measurements (CDOM/EEMS) from all stations/depths sampled throughout the cruise. We also plan on collecting large volumes (~10 L samples) for DIC photochemistry experiments back at SkiO. |
|
Summary of Facility Requirements: |
For DIC photochemistry, we require a full Niskin for each sample (1 surface sample per station) and fridge space for these samples. For the proposed DOC/DIC/CDOM/EEMS survey work, we require <1 L per Niskin bottle, a CTD rosette, and freezer space to store DOC samples for analysis back at SkiO (in 40 mL bottles). Ideally, I will gravity filter (0.2 um) samples directIy from Niskin bottles but can use less if water requirements are high (~40 mL required for DOC, ~20 mL for DIC, and ~10 mL for CDOM/EEMS). We propose to bring a Horiba Aqualog to run CDOM/EEMS at sea, which will require approximately 4 linear feet of bench space. It is best to run optics on fresh samples at sea, but if this is not possible, samples can be stored cold and run at SkiO. Additionally, because we are interested in using results from this cruise in remote sensing models, any optical sensor packages that can be in included (e.g. O2 sensor, Irradiance, CDOM fluorescence, and Chl fluorescence) will be useful data for our project. |

Description of Repeating cruise requirements: |
We are requesting time for two cruises in the spring (March) and summer (July) of 2018. We propose that they will both follow the same onshore to offshore transect to beyond the Gulf Stream in the South Atlantic Bight. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We would like the Savannah because the researchers are based at Skidaway, and the Savannah has adequate space and facilities to meet our needs. |
