Summary of Field Work: |
We wish to sample a tracer released at 1100 m depth near the Deepwater Horizon well rupture site. The tracer was released 1 August 2012 and will have spread over an area of order 300,000 square km by July 2013. Sampling will be by Conventional CTD/Rosette. Analysis is by gas chromatography on board ship. |
|
Summary of Facility Requirements: |
CTD winch with wire led through A-frame on stern. Clean surface seawater. Met data. Ship ADCP. |
|
Summary of other requirements and comments: |
Above requirements for surface seawater and met data are anticipated for anciliary projects. |

|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Survey of a tracer patch approximately one year after tracer release (which was on 1 August 2012). Start dates a bit earlier than this have the advantage of decreasing the probability of encountering a hurricane and also the possibility of another cruise funded to study mixing in Drake Passsage in late summer/early fall 2013. |
