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.

Science Party
Chief Scientist: Donna J. Shillington, LDEO
# in Science Party 15 # of different science teams 1 # Marine Technicians to be
provided by ship operator:
(include in science party total)
Explanation of Science Party Requirements and Technician Requirements We will have several co-chief scientists and watchstanders to stand watches for 24 hour operations in the science party. We will also have several OBSIP engineers to support OBS operations. We also plan to use this as a training opportunity for young scientists. From the Langseth, we would request adequate technical personnel for data acquisition with the 15-km streamer, including providing navigation, etc. The Langseth's technical staff can recommend the correct number of people needed for this cruise.
