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: Hikurangi Ocean Bottom Investigation of Tremor and Slow Slip (HOBITSS) Project Status: Submitted
Principal Investigator: Laura Wallace, UTIG Project Institution: UTIG
Project ID: 103759 Version #: 2
Date Submitted: 1/31/2013 5:34:00 PM Created By: Laura Wallace
Date Last Modified: 1/20/2014 12:04:00 PM URI Serial #: None
Funding Agencies: NSF/OCE/MGG - 1334654 - Funded
Summary of Field Work: We will deploy 20 broadband ocean bottom seismometers (with absolute pressure gauges; APG), 4 trawl-resistant bottom pressure recorders (BPRs, with APG), 10 BPRs that are not trawl-resistant, offshore the NE coast of the North Island of New Zealand. The goal of the experiment is to study transient aseismic slow slip events (SSEs) and related seismicity (tremor, microseismicity) along the Hikurangi Margin in the North Island, New Zealand. These shallow SSEs occur at <5-15 km depth approximately every eighteen months just offshore Gisborne,New Zealand. They typically last 1-2 weeks and horizontal displacements of up to 3 cm at onshore cGPS sites. The offshore vertical displacements above the SSE source are expected to be 1-3 cm, considerably larger than for Cascadia SSEs, and identifiable using APG data.
Summary of Facility Requirements: Global class vessel for OBS deployment and recovery. Must be capable of holding 30 OBS and BPRs and 4 trawl-resistant shielded BPRs.

Description of Repeating cruise requirements: This is an OBS recovery cruise so needs to be 12 months after deployment cruise.
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
Need ship sufficient to recover 20 OBS, 10 Bottom Pressure Recorders (BPRs), and 4 BPRs with trawl shielding offshore NE coast New Zealand. It is a OBS recovery cruise, so needs to be 12 months after deployment cruise.

Foreign Clearance and Permitting Requirements
Foreign Clearance Required? Yes Coastal States:

New Zealand
 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?

description of any other special permitting requirements
(e.g., MMPA, ESA, IHA, Marine Sanctuaries, etc.)
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.
