Summary of Field Work: |
This will be a cruise dedicated to carry out AUV Sentry near-bottom magnetic survey in the Hawaiian Jurassic Basin (1) to obtain definitive Jurassic magnetic record and (2) to address our overarching question: Is Jurassic magnetic field behavior globally coherent? The proposed field work is designed to complete what we proposed for TN272 cruise (Nov.-Dec. 2011), with which AUV Sentry was properly operated only for two dives (20 % of what we originally proposed). |
|
Summary of Facility Requirements: |
Sentry AUV (National Deep Submergence Facility), CTD that is capable operating MISO TowCam |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
A global class vessel with CTD, big crane, acoustically quiet environment with USBL installation (by NDSF-Sentry team), including Revelle, Melville, Kilo Moana, is the best choice to operate AUV Sentry. |
