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: The Thermal Regime of the Hikurangi Subduction Zone and Shallow Slow Slip Events, New Zealand Project Status: Submitted
Principal Investigator: Robert N. Harris, OSU_COAS Project Institution: OSU_COAS
Project ID: 103984 Version #: 3
Date Submitted: 7/24/2013 2:53:00 PM Created By: Robert N. Harris
Date Last Modified: 7/1/2014 8:55:00 AM URI Serial #: None
Funding Agencies: NSF/OCE/MGG - 1355878 - Funded
Summary of Field Work: We propose to collect heat flow and seismic reflection data offshore the northern and southern Hikurangi margin to develop a process-based understanding of the thermal structure of the Hikurangi subduction zone. The northern field study area is underlain by an aseismic creep-dominated subduction interface and is the site of repeated shallow (< 15 km depth) slow slip earthquakes (SSEs). The southern field area contrasts strongly with the northern field area; here SSEs are deep (> 30 km) and geodetic studies indicate updip interseismic coupling on the plate interface, similar to in Cascadia. We will acquire ~15 high-resolution transects of closely-spaced heat flow measurements from well-characterized sites, increasing the number of publically available heat flow measurements from this continental margin by 2 orders of magnitude. Using sediment seismic velocities and thermal conductivities obtained from this experiment, we will expand coverage of heat flow using regional observations of gas hydrate-related bottom simulating reflections (BRSs).
Summary of Facility Requirements: Global class vessel for seismic and heat flow data collection. Should have
dynamic positioning capability for station keeping.
Summary of other requirements and comments: Will use OSU multipenetration heat flow probe and SIO seismic gear.

Repeating Cruise?

Description of Repeating cruise requirements:
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
There are two logistical issues with the New Zealand cruise.

1) We would like to precede the Hobbit OBS recovery cruise. Part of our cruise will be seismic reflection and we would like to use the OBSs to effectively extend our offset length which will help to get better seismic velocities.

2) Perhaps more pressing is that I also have a cruise scheduled in the Panama Basin in Feb. 2015. Our shipping people tell me it will take 6-8 weeks to ship the heat flow equipment from Panama to New Zealand. I still do not have definitive dates but we should be demobilizing from the Panama Basin cruise at the end of Feb. Based on my current understanding of the demob date for the Panama cruise I would request a start date of May 15th, but this gets into the southern winter. I have contacted our shipping people and will look at options for air freighting the heat flow equipment. Currently there is only one set of heat flow equipment in the U.S. academic community.

Foreign Clearance and Permitting Requirements
Foreign Clearance Required? Yes 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
 Questions about ITAR/EAR regulations?

Port Calls
Requested Start Port Intermediate Port(s) Requested End Port
Napier, New Zealand None Napier, New Zealand
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops
Port chosen due to proximity to deployment site and due to availability of cranes etc. for loading/unloading equipment. Gisborne NZ also considered as a port, much closer to our deployment area, but the Gisborne port may be too small.
