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: A community seismic experiment targeting the pre-, syn-, and post-rift evolution of the Mid Atlantic US margin Project Status: Submitted
Principal Investigator: Harm Van Avendonk, UTIG Project Institution: UTIG
Project ID: 103427 Version #: 5
Date Submitted: 6/19/2012 3:09:00 PM Created By: Harm Van Avendonk
Date Last Modified: 6/7/2016 1:13:00 PM URI Serial #: None
Funding Agencies: NSF/OCE/MGG - 1249900 - Funded
NSF/EAR - 1249900 - Funded
Summary of Field Work: We propose to acquire multichannel seismic reflection data, marine and land seismic refraction data, and land and marine broadband seismic data in the Mid-Atlantic states (around Cape Hatteras) in May/July 2014. Broadband ocean-bottom seismometers (OBSs) will be deployed for one year, so they must be retrieved a year later in May/June 2015.
Summary of Facility Requirements: We request the use of several vessels for this proposed project. Acquisition of marine seismic reflection and refraction data will be require 33 days at sea of the R/V Marcus Langseth in June/July 2014. We request the R/V Knorr to deploy a total of 30 broadband OBSs over 12 days in May 1-15, 2014. The R/V Knorr is also requested in May 2015 for 12 days to retrieved the broadband OBSs. We also request 26 days on the R/V Endeavor in June/July 2014 to deploy and recover 47 short-period OBSs.
Summary of other requirements and comments: In our schedule, the R/V Marcus Langseth starts her 33-day ship cruise 1 day after the start of the 26-day cruise of the R/V Endeavor. The R/V Endeavor is the ship that we use for short-period OBS deployments.

Repeating Cruise?

Description of Repeating cruise requirements:
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
We request the Marcus Langseth for an onshore-offshore active-source seismic experiment. The project involves many students in data acquisition on-land and offshore. To accommodate their university schedule, we prefer to start the marine seismic cruise no earlier than May. Later in the summer the chance of a hurricane encounter is larger, so we prefer to start the ship cruise before the end of May.

This project uses OBSIP ocean-bottom seismometers that will be deployed from another ship (not the Marcus Langseth). The seismic waves will also be recorded on-land by land-seismic stations from the Earthscope FlexArray.
