Summary of Field Work: |
This project consists of two legs on R/V Falkor in Nov-Dec 2015, each using the port of Guam. Leg 1 will use a CTD and AUV Sentry to survey systematically for hydrothermal plumes along the Mariana back-arc between 13°N and 18.5°N. This Leg will identify and map new vent sites. Leg 2 will then make dives with the Nereus ROV to visually explore the newly discovered vents and sample their fluid chemistry and biology. |
|
Summary of Facility Requirements: |
Leg 1 (21 days) requires the Sentry AUV. Leg 2 (22 days) requires Nereus in ROV mode. We have chosen Sentry for use on Leg 1 because it is the most efficient AUV for this purpose (including dive duration and survey speed), and Nereus is required for Leg 2 because it is the only ROV currently capable of making dives deeper than 3000 m from R/V Falkor. |
|
Summary of other requirements and comments: |
The latest update from Eric King of Schmidt Ocean Institute is that these cruise legs are likely to be scheduled in Nov-Dec 2015. |
