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: Quantifying the biological, chemical, and physical linkages between chemosynthetic communities and the surrounding deep sea Project Status: Submitted
Principal Investigator: Erik Cordes, Temple Project Institution: Temple
Project ID: 105197 Version #: 2
Date Submitted: 2/10/2016 11:31:00 AM Created By: Erik Cordes
Date Last Modified: 1/9/2017 8:05:00 PM URI Serial #: None
Funding Agencies: NSF/OCE/BIO - 1635219 - Funded
Summary of Field Work: We propose two research cruises in 2017 and 2018 that will depart and return to Puntarenas, Costa Rica. The first site is within a 12-hour steam from port. We plan 4-6 days of work at each of 3 strategically selected sites on subducting seamounts, plus additional time for oceanographic and bathymetry surveys, for a total of approximately 20 days at sea per cruise. We will utilize either the Jason ROV or a combination of the Alvin HOV and the Sentry AUV to complete the benthic surveys and sampling. This will be augmented through the use of the user-supplied Wire Flyer water-column sampler to provide a 3-dimensional view of these habitats. The Wire Flyer is a ship-towed (at 3-4 knots) autonomous vehicle that slides up and down a standard 0.322 cable in a controlled manner (Roman and Hebert, 2011)
Summary of Facility Requirements: We will need an ROV or HOV/AUV combination, ship with dynamic positioning, 0.322 wire for the Wire Flyer, CTD/rosette, ship-board multibeam, cold room facilities, and -80 ultracold freezer.

Requested Ship, Operating Days and Dates
Year: 2017 Ship/Facility: Alvin
Optimum Start Date: 5/15/2017 Dates to Avoid: There are two cruises requested, and this cruise should be after the start of the project, but before the end of the first fiscal year. Cordes has another conflict beginning mid-September 2017.
Earliest Start Date: 1/1/2017 Multi-Ship Op: No
Latest Start Date: 8/1/2017 Other Ship(s): None.

Repeating Cruise?

No Interval:   # of Cruises:  

Description of Repeating cruise requirements: None
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
Alvin / Sentry is preferred. Alvin alone will not suffice, as we plan a number of near-seafloor surveys that would require Sentry. The alternative to this combination is the ROV Jason. If Jason, we do not have a preference for the support ship. Cordes currently has a conflict with a cruise that is scheduled for 9/20/17 - 10/22/17.

Foreign Clearance and Permitting Requirements
Foreign Clearance Required? Yes Coastal States:

Costa Rica
 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.)
Foreign clearance will require a Costa Rica observer. We have been in contact with them and have previously operated in this area, so are familiar with all of the necessary permits.

The Wire Flyer is a ship-towed (at 3-4 knots) autonomous vehicle that slides up and down a standard 0.322 cable in a controlled manner (Roman and Hebert, 2011). Using the lift force created by wing foils, the vehicle can achieve controlled up and down profiling velocities (0- 2.25 m/sec) within a specified depth band down to ~900 m depth. The high repetition rate of the Wire Flyer provides a far more complete data set than would be possible with repeat ship board CTD casts. While being towed, updated commands and condensed data samples can be sent to and from the Wire Flyer via an acoustic modem to refine the sampling speed and depths to ensure proper coverage. The vehicle typically creates high horizontal resolution (T, S, O2, Chl, CDOM, turb) sections. For this project a Satlantic Deep SeaFET pH sensor will be integrated along with the SBE 49 FastCAT, Aanderaa 4831f O2 sensor and Wetlabs triple Ecopuck. These sensors will also be available to be used on the submersibles.
