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 Title: Collaborative Research: Relationship between plate boundary
obliquity, strain accommodation, and fault zone geometry at
oceanic-continental transforms: The Queen Charlotte Fault
Project Status: Submitted
Principal Investigator: Lindsay Worthington, UNM Project Institution: UNM
Project ID: 106020 Version #: 5
Date Submitted: 1/22/2018 2:26:00 PM Created By: Emily Roland

Funding Agencies: NSF/OCE/MGG - 1824927 - Funded
Summary of Field Work: Characterization of earthquake source properties and fault zone structure along an oceanic-continental transform margin. This ship time request includes the second of two OBS deploy/recovery cruises and will have the goal of recovering 28 US broadband OBS and 34 Canadian OBS (new CA pool) in late summer 2021, with a departure/return port of Ketchikan, AK. Deployment will have been completed by Canadian Vessel R/V Tulley (not included in this request).

Each cruise will be staffed by two PIs (Likely Roland and Walton) in addition to the regular OBSIP and technical support staff. Also, we plan to open the programs to fill a few additional berths with undergraduate or graduate students.
Gravity, magnetics and bathymetry will be collected along the deployment transit track.
Summary of Facility Requirements: The recovery of the 28 (US) and 34 (CA) OBS will be most efficient if organized over two legs, to allow for OBS Technical personnel from two national groups to disembark and reload. We propose to recover the OBS using a global-class vessel available on the west coast. The Thompson or Sikuliaq are viable options. We require a vessel with sufficient deck space to accommodate up to 40 OBS’s, but do not plan to use any of the US shallow water TRM instruments. We require dry/wet lab space for staging the instruments and a large crane or A-frame for recovering instruments. Multibeam and gravity capability will provide important ancillary data.
Summary of other requirements and comments: We have calculated that the recover of US instruments will require 5 days of ship time, including transit to Ketchikan, Alaska, and that recovery of the Canadian instruments will require 6 days of ship time. This time includes 15% contingency time and would allow for the personnele swap.

The passive source OBS legs of this project could be coordinated in concert with active source shooting that is accompanying the passive observations, and is being led by coPI Roland. A ship time request for the R/V Langseth has been submitted by the PI Worthington, UNOLS Project ID #: 106013.

Requested Ship, Operating Days and Dates
Year: 2022 Ship/Facility: Sikuliaq
Optimum Start Date: 8/1/2022 Dates to Avoid: Sea conditions will likely prohibit OBS recovery in Fall and Winter months.
Earliest Start Date: 8/20/2022 Multi-Ship Op: No
Latest Start Date: 10/15/2022 Other Ship(s): For the OBS recovery leg, there will not be multi-shop operations, however for the Active source and deployment legs, this will be necessary (See project 921237).

Repeating Cruise?
(within same year)
No Interval:   # of Cruises:  

Description of Repeating cruise requirements: No repeating cruise is necessary.
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
We require a global (preferably) or ocean class vessel that is operating in the NE Pacific in 2021.
The Thompson or Sikuliaq would be ideal vessels for this work. OBS recovery time has been calculated assuming rise rates and recovery time specified by OBSIP instrument planning guidelines, transit between stations, and 15% contingency time. This includes transit to the first station, as well as a port stop between US and Canadian instrument recoveries, planned for Ketchikan, AK, to swap OBS engineering personnel. Although not entirely necessary, in case of rough weather conditions, a heave compensating winch may be useful for instrument recovery.
