Summary of Field Work: |
Mapping and petrological sampling. We will do round the clock sampling of the rift valley of the mid-Atlantic ridge |
|
Summary of Facility Requirements: |
Need a large ship able to handle science party of >20 people. Multibeam, trawl winch for dredging, hydrowinch for "rock coring", hood and lab facilities for on board chemical analysis. |
|
Summary of other requirements and comments: |
Round the clock dredging with miniature autonomous
lume recorders, multibeam mapping and surveys. Need multibeam tech and also
dredging tech(s). Science party includes ten undergraduates, who will need
to learn a lot... |

Optimum Start Date:
|
6/10/2012 |
Dates to Avoid: |
The cruise involves undergraduates so needs to be consistent with their semesters. Mid-May through mid-August are best. In a pinch, late December through end January could work, though weather is poor. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Dates are for weather and undergraduate logistics. Ship needs to have multibeam, dredging and rock coring capabilities for science party of 20 or more. |

Explanation of Science Party Requirements and Technician Requirements |
Broader impacts includes a sea-going experience for 8-10 undergraduates. Round the clock dredging and rock coring optimally has two deck techs experienced with sampling operations. Multibeam both for survey and sampling work requires data technician/processor |
