Summary of Field Work: |
Characterization of hydrography, larval abundance and distributions, and population genetics of seeps in the intra-American sea to determine processes and dynamics of connectivity.
This work includes mooring deployments of 1-year duration at seep sites located the Gulf of Mexico and at Blake Ridge on the Atlantic shelf off the east coast of the United States. We plan to sample benthos at seeps sites (including new seeps located off Nantucket and Virginia) for reproductive biology and genetic analysis using Jason and we will sample the water column at the seep sites with a MOCNESS system. We plan to map seep sites in the Gulf of Mexico with Sentry. |
|
Summary of Facility Requirements: |
We will need Jason for benthic sampling (Alvin would be ok, but we prefer Jason), a MOCNESS system (with tech) for pelagic samplingand Sentry for mapping. |
|
Summary of other requirements and comments: |
For one or both cruises, we would like to use telepresence in collaboration with the URI Inner Space Center (Katy Bell Croft is our contact) if the schedule permits and if we can find support for living expenses and other associated costs.
NOTE: We will also need to request mooring deployment and recovery cruises, but how these play out depend on scheduling of these cruises and recovery of moorings from Trinidad and Tobago (in May). |

Optimum Start Date:
|
5/1/2014 |
Dates to Avoid: |
We have been asked to wait until 2014 for this cruise. Optimal dates under this condition May through mid July, to avoid the heart of the hurricane season.
We also need 2 to 3 weeks between this cruise and the GoM seeps cruise. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We proposed 5 days on station and were recently approved by Dave Garrison (email of 18 Dec 2012) to add 4 days to allow us to sample one of the Nantucket seeps and the Cape Henry seep recently located by NOAA colleagues.
We prefer to work in the May through mid-July window to avoid hurricane season; I have included two additional days for weather.
Science has no special mob demob number of days; I assume Jason and Sentry need at least two days as place holders. |
