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: Do symmetric and asymmetric segments on the mid-Atlantic Ridge have distinct geochemical signatures Project Status: Submitted
Principal Investigator: Charles H. Langmuir, Harvard Project Institution: Harvard
Project ID: 102654 Version #: 1
Date Submitted: 8/13/2010 10:51:00 AM Created By: Charles H. Langmuir
Date Last Modified: 6/21/2011 11:22:00 AM URI Serial #: None
Funding Agencies: NSF/OCE/MGG - 1061264 - Funded
Summary of Field Work: Mapping and petrological sampling. We will do round the clock sampling of the rift valley of the mid-Atlantic ridge
Summary of Facility Requirements: Need a large ship able to handle science party of >20 people. Multibeam, trawl winch for dredging, hydrowinch for "rock coring", hood and lab facilities for on board chemical analysis.
Summary of other requirements and comments: Round the clock dredging with miniature autonomous
lume recorders, multibeam mapping and surveys. Need multibeam tech and also
dredging tech(s). Science party includes ten undergraduates, who will need
to learn a lot...

Requested Ship, Operating Days and Dates
Year: 2012 Ship/Facility: Knorr
Optimum Start Date: 6/10/2012 Dates to Avoid: The cruise involves undergraduates so needs to be consistent with their semesters. Mid-May through mid-August are best. In a pinch, late December through end January could work, though weather is poor.
Earliest Start Date: 5/15/2010 Multi-Ship Op: No
Latest Start Date: 7/20/2010 Other Ship(s):

Description of Repeating cruise requirements:
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
Dates are for weather and undergraduate logistics. Ship needs to have multibeam, dredging and rock coring capabilities for science party of 20 or more.

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)?
No If yes, have you applied for the necessary permits through your export control office? No

Science Party
Chief Scientist: Charles H. Langmuir, Harvard
# in Science Party 24 # 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 Broader impacts includes a sea-going experience for 8-10 undergraduates. Round the clock dredging and rock coring optimally has two deck techs experienced with sampling operations. Multibeam both for survey and sampling work requires data technician/processor
