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.

  SISIE  -  2018  -  Marcus Langseth  
  Project Information  
Project Title: Collaborative Research: SISIE: South Island, New Zealand, Subduction Initiation Experiment Project Status: Submitted
Principal Investigator: Michael Gurnis, CalTech Project Institution: CalTech
Project ID: 105387 Version #: 1
Date Submitted: 7/25/2016 11:46:00 AM Created By: Michael Gurnis
Date Last Modified: 1/25/2018 12:37:00 PM URI Serial #: None
Funding Agencies: NSF/OCE/MGG - 1654766 - Funded
Summary of Field Work: We will use the R/V Langseth to deploy and recover 23 OBS in two deployments, use the airguns on the Langseth to shoot two seismic refraction lines, and then use the 12 km streamer to collect 1,730 km of MCS lines.
Summary of Facility Requirements: R/V Langseth, its airgun and the 12 km streamer. We will use the multi-beam capability, gravimeter and magnetometer.
Summary of other requirements and comments: We will bring with us 23 OBS from UTIG

Requested Ship, Operating Days and Dates
Year: 2018 Ship/Facility: Marcus Langseth
Optimum Start Date: 2/15/2018 Dates to Avoid: Avoid austral winter season (April September) due to likely bad weather - rough seas will degrade the quality of the data and make operations more difficult
Earliest Start Date: 11/1/2017 Multi-Ship Op: No
Latest Start Date: 3/15/2018 Other Ship(s):

Repeating Cruise?
(within same year)
No Interval:   # of Cruises:  

Description of Repeating cruise requirements:
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
The R/V Langseth is required because of its unique seismic capabilities.
The dates are chosen to conform to Austral Summer and the NSF Regional Seismic Plan
Work Area for Cruise
Short Description of Op Area
for use in schedules:
Puysegur Ridge
Description of Op Area: Within 5 nm of the New Zealand coast on closest approach; water depths 100 m to 5500 m;
moderate to low levels of commercial shipping; some fishing. Puysegur Ridge, Puysegur Trench, Snares Zone, Solander Basin. New Zealand EEZ and international waters
Op Area Size/Dia.: 350 nm X 200 nm

Seismic operations will include using 6600 cu in airguns and MCS with 12 km streamer and XBTs during seismic acquisition. Multibeam, sub-bottom profiler and gravity while underway.
When the streamer is not deployed, we will deploy the Geometrics 882 Magnetometer.
