Summary of Field Work: |
14 days of Jason II dives sampling rocks from a moderately steep slope and 10 days of Sentry dives mapping (sidescan) and collecting magnetic data. Plus setting up transponder networks in two areas and dredging during down time. Concurrent Jason II and Sentry operations for about 5 days, depending on weather conditions etc. |

Description of Repeating cruise requirements: |
. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Roger Revelle because main winch has a fibre optic cable so as to avoid having an 'on deck' winch (because we will be using both Sentry and Jason II and their associated vans). February/March preferred due to optimal weather conditions(although not a harsh weather environment) and lower shipping/travel costs. Total on site days is our best guess to complete Sentry & Jason II ops, including some overlapping operations. |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
Isla de Pascua, Chile |
None, , None, |
Bahia de Valparaiso, Chile |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Isla de Pascua (Easter Island) is very close to the operation area, but has limited port facilities. Valparaiso is a reasonably close major port. Longer transit at end of cruise will allow sample processing/curation, and preparation for shipping. |

Explanation of Science Party Requirements and Technician Requirements |
We propose 9 scientists (including senior scientists thru graduate students) to man Jason II operations and dredging and rock sampling (3 teams of 3), and 3 scientists to carry out the Sentry/magnetics/sidescan operations (1 team). We also need a computer technician and a marine technician for dredging.
An additional 9 NDSL persons are recommended for Jason operations and 5 NDSL persons arerecommended for Sentry operations. |
