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 Proposal: Seismic Investigation of the Rainbow Hydrothermal Field and its Tectono/Magmatic Setting, Mid-Atlantic Ridge 36° 14’N Project Status: Submitted
Principal Investigator: Juan Pablo Canales, WHOI Project Institution: WHOI
Project ID: 102143 Version #: 1
Date Submitted: 8/11/2009 9:48:00 AM Created By: Juan Pablo Canales
Date Last Modified: 9/5/2012 9:48:00 AM URI Serial #: None
Funding Agencies: NSF/OCE/MGG - 0961680 - Funded
Summary of Field Work: (1) 3-D ocean-bottom-seismometer tomography study of the Rainbow vent fields and surrounding area. (MAR 36°14'N), using 46 OBS on a 30x80 km grid and about 7 days of airgun shooting to the instruments.
(2) Multi-channel Seismic Study of the same area using 8-km-long streamer. About 6 days of airgun work (~850 km of seismic profiles).
(3) A passive microearthquake study (`6 months) of same area. 15 OBS will record seismicity on the seafloor for ~ 6 months duration. These long-term short-period instruments will be deployed at end of seismic shooting and left on seafloor for later retrieval be a separate ship.
Summary of Facility Requirements: R/V Langseth with airgun source array and MCS capabilities in June/July of 2011.
OBS: single-source (2D) 4 x 10-gun strings (1650 c.i. per string).
MCS: single-source (2D) 2 x 10-gun stings (1650 c.i. per string).
One streamer (2D config.) with 8-km-long active section. Differential GPS.
Full compliment of Langseth sonar capabilities (multibeam, sub-bottom profiler, PAM), magnetometer, and gravimeter.
A separate "ship of opportunity" to retrieve instruments in late 2011 or early 2012.

Requested Ship, Operating Days and Dates
Year: 2013 Ship/Facility: Marcus Langseth
Optimum Start Date: 6/1/2013 Dates to Avoid: Avoid northern hemisphere winter as high seas will make OBS and MCS operations dangerous and difficult. There will also be high noise levels at that time, so it is a bad time for recording data.
Earliest Start Date: 4/1/2011 Multi-Ship Op: No
Latest Start Date: 8/1/2011 Other Ship(s):
