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: Axial 3-D - Exploring the linkages between complex magma chamber structure, caldera dynamics, fluid pathways and hydrothermal venting. Project Status: Submitted
Principal Investigator: Adrien Arnulf, UTIG Project Institution: UTIG
Project ID: 105456 Version #: 10
Date Submitted: 8/10/2016 4:59:00 PM Created By: Adrien Arnulf
Date Last Modified: 6/27/2018 11:10:00 AM URI Serial #: None
Funding Agencies: NSF/OCE/MGG - 1658199 - Funded
Summary of Field Work: In order to investigate the physical state, distribution, shape and connectivity of magma volumes, fracture networks and fluid pathways, we propose to collect a 3D seismic reflection dataset in a 40 by 17 km box, and eight transects of 2D long-offset seismic data over Axial volcano at the intersection of the JDFR and the Cobb-Eickelberg (CE) hotspot chain.
Summary of Facility Requirements: We are requesting the R/V Marcus Langseth for a 33 days-long active-source seismic survey in Summer 2018. First, we will deploy a 3-D seismic array, towing four 6-km-long streamers separated by 150 m, with two flip-flopping source arrays (tuned ~3300 cu. in. each) separated by 75 m. Then, we will deploy a single 15-km-long streamer for several 2-D transects.

Explanation of Science Party Requirements and Technician Requirements 13 technicians are needed to deploy, operate and recover an array of four 6-km-long streamers on-board the R/V M. Langseth.
A group of 16 scientists, including the PIs, grad students and early career scientists is typical on a 3D seismic survey.

We need the streamer capabilities of the R/V Marcus Langseth in order to acquire two datasets:
_ Our main dataset will be recorded in a 40 x 17 km 3D seismic volume, towing four 6-km-long streamers separated by 150 m, with two flip-flopping source arrays (tuned ~3300 cu. in. each) separated by 75 m.
_ Our second dataset consist in 2D transects recorded using a single 15-km-long streamer.
