Summary of Field Work: |
This is a 3-year field program request using ROV Jason or HOV Alvin, with a dive program annually each year. We propose to deploy 15 newly designed MISO high-T vent temperature loggers with attitude sensing at ~7-10 hydrothermal vents along the EPR axis between 9° 45’-51’N, and recover/redeploy them annually over 3 years to capture the run-up to the next EPR eruption.
9 ROV Jason dive days or 9 Alvin dives are requested each year to recover and redeploy the loggers and sample hydrothermal fluids using isobaric gas-tight samplers so that the combined time-series temperature and geochemical datasets can be used to predict the onset of the next EPR 9° 50’N eruption and validate models for volcanic/hydrothermal interaction. |
|
Summary of Facility Requirements: |
Our 1st field program is scheduled for March-April 2021 on RV Revelle with ROV Jason and AUV Sentry
For our 2nd field program in late 2021 or early 2022 we prefer to use Alvin and RV Atlantis to carry out 9 dives at the EPR 9 50'N study site
For our 3rd field program in late 2022 or early 2023 we prefer to use Alvin and RV Atlantis to carry out 9 dives at the EPR 9 50'N study site in conjunction with Sentry AUV mapping at night - we are requesting the Sentry mapping in order to be prepared to map post-eruption topography.
4-5 Elevator deployments are required for instruments, sampling and imaging. Night operations may include TowCam surveys |
|
Summary of other requirements and comments: |
We are willing to share/collaborate/coordinate field work with other PIs who have funded diving work at the EPR 9 50'N area.
Our night/ancillary operations for our 2nd field program will consist of and MISO TowCam deep-sea camera lowerings |

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Manzanillo is the closest port to the field area. We are willing to transit to/from San Diego, CA if logistics and other consideration indicate that is the best option. In that case the total transit should be recalculated at 12 days total. |
