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: Seismic imaging of volcano construction, underplating and flexure along the Hawaii-Emperor Seamount Chain Project Status: Submitted
Principal Investigator: Donna J. Shillington, LDEO Project Institution: LDEO
Project ID: 105651 Version #: 1
Date Submitted: 2/8/2017 10:40:00 AM Created By: Donna J. Shillington
Date Last Modified: 4/12/2018 11:44:00 AM URI Serial #: None
Funding Agencies: NSF/OCE/MGG - 1737245 - Funded
Summary of Field Work: The goal of this project is to determine crustal structure along and across the Hawaii and Emperor seamount chains using a series of 2D seismic reflection/refraction profiles. We envisage that the work would take place during two parts. The first part would involve an experiment from Honolulu-Honolulu using the Langseth. The second part would involve an experiment aboard the Langseth from Honolulu to Adak, Alaska. We chose these ports based on the Langseth regional plan, but could use different ports as needed. OBS deployments and recoveries as well as acquisition of seismic reflection/refraction data would all take place from the Langseth.
Summary of Facility Requirements: We require the large, tuned air gun array and long streamer of the Langseth for acquiring seismic refleciton and refraction data along our profiles. We will also be deploying and recovering OBS, and will need space for prepping and storing them and a suitable crane for deployment/recovery.

Requested Ship, Operating Days and Dates
Year: 2019 Ship/Facility: Marcus Langseth
Optimum Start Date: 8/1/2019 Dates to Avoid: Seeking to avoid bad weather in fall/winter/early spring at relatively high latitudes. In our ideal plan, this cruise would take place after the Hawaii Island cruises.
Earliest Start Date: 6/1/2019 Multi-Ship Op: No
Latest Start Date: 9/15/2019 Other Ship(s): This cruise would constitute the second part of our project following the programs in the Hawaiian islands also included in this request.

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)?
Yes If yes, have you applied for the necessary permits through your export control office? No
 Questions about ITAR/EAR regulations?

Port Calls
Requested Start Port Intermediate Port(s) Requested End Port
Honolulu, HI, USA None Adak Naval Air Station, AK, USA
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops
The field area is quite remote. Several other ports would be possible for beginning/ending the cruise, particularly Tokyo. We chose these particular start and end ports based our understanding of the Langseth's regional plan.

This cruise would be collaborative with GEOMAR in Germany, who would provide some OBS for the proposed work. So, we would also need to coordinate with their OBS group for this program.
