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.

Funding Agencies: NSF/OCE/MGG - 1031769 - Funded
NSF/OCE/ODP - 1031769 - Funded
Summary of Field Work: 3D MCS acquisition in a 55 by 25 km box in the Atlantic Ocean offshore Galicia Spain. We will also be shooting into an array of 78 European OBS's.
Summary of Facility Requirements: 3D seismic reflection survey, dual sources, four six km streamers deployed 200 m apart. Gravity, Magnetometer, Swath Bathymetry.
Summary of other requirements and comments: We will need to coordinate schedules with RV Poseidon, which will be deploying and recovering OBS's.
