Ship Request

STR Management has moved to MFP

The US Academic Research Fleet is moving to Marine Facilities Planning (MFP) for scheduling initially and eventually cruise planning.

For all NEW or RESUBMITTED Projects/Ship Time Requests, go to and create a new SME. Some STRs for projects starting in 2022 and beyond have already been moved to Marine Facilities Planning ( Check your MFP Science Portal for any projects that might already be moved. If you need to make edits to projects that begin in 2022 and beyond, please contact for assistance. Be sure to indicate the Project and STR IDs that you would like to edit. For more information on getting into MFP, see the More Information button below.

  Project Information  
Project Title: Collaborative Research: Monitoring hydrothermal fluid origin, crustal permeability and seafloor morphology in preparation for the next volcanic eruption at the East Pacific Rise axis, 9° 45’-53’N Project Status: Submitted
Principal Investigator: Daniel J. Fornari, WHOI Project Institution: WHOI
Project ID: 106579 Version #: 4
Date Submitted: 8/13/2019 1:35:00 PM Created By: Daniel J. Fornari
Date Last Modified: 9/28/2020 11:21:00 PM URI Serial #: None
Funding Agencies: NSF/OCE/MGG - 1949485 - Funded
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

Requested Ship, Operating Days and Dates
Year: 2021 Ship/Facility: Roger Revelle
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
Earliest Start Date: 3/15/2021 Multi-Ship Op: No
Latest Start Date: 5/1/2021 Other Ship(s): none

Operating Days Needed: Science Days Mob Days De-Mob Days Estimated Transit Days Total Days
18 4 2 13 37
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.

Foreign Clearance and Permitting Requirements
Foreign Clearance Required? No Coastal States:

 Important Info on Foreign Research Clearances  

Are you or any member in your science party bringing in any science equipment items which are regulated for export by the International Traffic in Arms Regulations (ITAR) and/or the Export Administration Regulations (EAR)?
No If yes, have you applied for the necessary permits through your export control office? No
 Questions about ITAR/EAR regulations?

Comments about foreign clearance requirements or
description of any other special permitting requirements
(e.g., MMPA, ESA, IHA, Marine Sanctuaries, etc.)
field area is in international waters, no EEZ clearance for science is necessary
Port Calls
Requested Start Port Intermediate Port(s) Requested End Port
San Diego, CA, USA None San Diego, CA, USA
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops
We have opted for transit starting from San Diego, CA to start the cruise and transit directly to the field area to facilitate mobilization and shipping of equipment needed for the cruise. We are willing to return to San Diego or end in Manzanillo, MX or Puntarenas, CR

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.
