|
Summary of Field Work: |
We propose to conduct field work off the coast of Southern California, to quantify the distribution and rate of ethane and propane oxidation in marine water. |
|
Summary of Facility Requirements: |
We require an oceanographic research vessel equipped with CTD rosette and ~23 niskin bottles. We also require a radiation van for use of a tritium-based radiotracer, and laboratory facilities where gas chromatographs can be installed for the duration of the cruise. |
|
Summary of other requirements and comments: |
The work proposed here could be readily integrated with the SEEPS 13 cruise funded through the Dimension of Biodiversity (DoB) program. We therefore request 7 additional day of ship time for the SEEPS 13 cruise to conduct the work proposed here. This value added arrangement will benefit BOTH projects. This project will be able to conduct wire line operations at night time, and will be able to use the extra time needed for for offshore trash dumps and water making days. The DoB project will benefit from extra days of operations, as the in-situ incubations proposed can be run for a longer time, to allow a higher degree of isotope label incorporation. Valentine is the PI on both projects, allowing for seamless integration of operations. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We request 7 days of ship time added to the SEEPS 13 cruise funded through the Dimensions of Biodiversity program. The same PI is leading both projects. This situation is value added as this award will use the wire time at night over the course of the cruise, allowing for the experiments to be run during the daytime hours at different locations. At-least 14 days are needed at sea to conduct the temporal and spatial studies proposed here, which is readily accommodated by the summed duration of the two projects. This sharing will further reduce mob and demob time, will allow for the trash days and water making days to be used for offshore sampling, and will allow for a longer in-situ incubations for the DoB project - improving the chance of success for that research. |

We plan to use tritiated gases to quantify the oxidation rates of ethane and propane in ocean water, using a similar approach as we have done previously with methane.

CTD with 24 place rosette.
Based on recent results from Sentry (cruise completed in October, 2011), we request the use of Sentry again for this cruise. Sentry's multibeam and mass spectrometer will be used to identify sources of ethane and propane to the water column, which will guide sampling activities. |
