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 seven (7) 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: |
ROV Jason is requested in the first year 2021- as Alvin will be in overhaul and Atlantis will be in mid-life refit
We have received approval from NSF MGG (Sept 28, 2020) to include use of AUV Sentry for the planned 2021 RV Revelle cruise to complete and expand detailed near-bottom mapping of the EPR axial terrain in the 9deg 37N to 9 deg 57'N region
4-5 Elevator deployments are required for instruments, sampling and imaging. |
|
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 will consist of AUV Sentry surveying and MISO TowCam, deep-sea camera lowerings |

Optimum Start Date:

3/15/2021 |
Dates to Avoid: |
Alvin will be in overhaul in 2020-2021 and Atlantis will be in mid-life refit
Because of the time-sensitive nature of this research re the impending volcanic eruption at the EPR that is expected in the next few years we request priority scheduling for ROV Jason and RV Revelle in the Mar-May 2021 time frame in order to accomplish our field work and experiment/instrument deployments.
Do not schedule between June and November - EPR 950N weather is not acceptable for diving operations |

Repeating Cruise?
(within same year) |
No |
Interval: |
annual- every ~12 mos |
# of Cruises: |
3 |
|
|
Description of Repeating cruise requirements: |
annual over 3 years, ~12 mo interval is needed between cruises to recover and redeploy hiT self recording loggers and conduct annual sampling of hydrothermal fluids from the vents that are instrumented along the EPR axis between 9 45-51'N. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Note that we have requested in this STR both our 9 funded dive days, and the funded dive days for Mullineaux (4) and Arellano (5) and the calculated transit days and mob/demob days per the SIO scheduler.
ROV Jason is needed for 1st cruise as Alvin will be in overhaul
We have received approval to request use of AUV Sentry for the planned Mar-April 2021 Revelle cruise.
Note below **Very Important**
Research is VERY time sensitive in terms of the expected timing of the next EPR volcanic eruption which could occur any time in the next few years.
We need a large UNOLS global class vessel for the multi-PI work and ideally a mob/demob in San Diego if possible
We are willing to share a cruise leg with other PIs working at the EPR 9 50N area. |

Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
ROV Jason system is required to deploy/recover hiT vent loggers, other seafloor instruments, and collect hiT vent fluid samples from numerous vents for time series experiments.
AUV Sentry will be used to continue mapping the EPR axial terrain associated with the most recent 2005-2006 volcanic eruption to complete a baseline map against which we can quantitatively assess any future volcanic eruptions. |
