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: A 3D seismic investigation of the transition to seismogenic behavior along the southern Costa Rica subduction zone Project Status: Submitted
Principal Investigator: Nathan L. Bangs, UTIG Project Institution: UTIG
Project ID: 101741 Version #: 4
Date Submitted: 8/22/2008 12:50:00 PM Created By: Nathan L. Bangs
Date Last Modified: 7/14/2010 1:08:00 PM URI Serial #: None
Funding Agencies: NSF/OCE/ODP - ARRA 0851380 - Funded
Summary of Field Work: This project will acquire a 11 x 55 km volume of 3D seismic reflection data to examine the 3D structure of the Costa Rica convergent margin near Osa peninsula. The goal is to examine the structures and rock properties associated with the downdip transtion into the seismogenic zone along the plate interface. This project is in support of the IODP CRISP deep riser drilling program and the MARGINS-SEIZE initiative.
Summary of Facility Requirements: We request 30 days for the R/V Langseth to use in 3D seismic mode. We will use 4-5,000 m streamers with 150 m separation. We will use the full acoustic navigation for streamer location. We will shoot in dual source mode at 25 m intervals and record for 9 sec.

Science Party
Chief Scientist: Nathan L. Bangs, UTIG
# in Science Party 10 # 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 need sufficient technicians to conduct the proposed 3D operations. This will include observers, airgun techs, navigators and computer techs. I don't know what Lamont expects to provide for 3D programs, but it will have to be discussed prior to the cruise.
