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: Do improved absolute plate motion models based on Cretaceous Western Pacific seamounts relate Louisville to Ontong-Java? Project Status: Submitted
Principal Investigator: Jasper Konter, UH_SOEST Project Institution: UH_SOEST
Project ID: 106314 Version #: 2
Date Submitted: 11/19/2018 4:53:00 PM Created By: Jasper Konter
Date Last Modified: 7/7/2020 8:08:00 PM URI Serial #: None
Funding Agencies: NSF/OCE/MGG - 1912934 - Funded
Summary of Field Work: This projects aims to characterize West Pacific seamounts for their original age and chemical composition (of the rocks), in order to redefine the plate motion history of the Pacific Plate.

The work at-sea will consist of multibeam mapping and rock dredging of West Pacific seamounts between the Mariana Trench and Wake Island. The work will focus on using the multibeam system to locate potential dredging locations, based on mapped topography, and the intensity of back-scattered energy from the multibeam system. The most promising site will be targeted for rock dredging; due to the coral reefs on the target seamounts, dredging will focus on the deep flanks of the seamounts, between 5-3km depth. We plan to target 31 seamounts, mapping and dredging, in 24 hour operations.
Summary of Facility Requirements: As this is a dredging-focused cruise, we request two experienced dredging technicians for around the clock operations.

We will need a winch and wire for dredging operations, with ~10 km of wire (the westernmost seamount is at the edge of the Mariana Trench).

Dredging will be challenging in some weather conditions, so we request spare equipment, including multiple pingers, and 4 or more rock dredges.

We will also collect magnetics.

Furthermore, we will need space to store the collected dredged rocks (likely 3-5 pallets worth).
Summary of other requirements and comments: We plan to bring a large science crew (17 + 2 marine techs) to help process the rock samples, and will need sufficient bunk-space for personnel and lab-table space to process and dry the rock samples.

Requested Ship, Operating Days and Dates
Year: 2021 Ship/Facility: Kilo Moana
Optimum Start Date: 2/1/2021 Dates to Avoid: Mapping and dredging are sensitive to large swells, and January-April are the only months that average less than 1 typhoon/month in this area (known as typhoon alley). Mapping will be far less efficient in large swells, because the multibeam swaths will be much narrower. Dredging is affected because large swells will limit the ship's headings while dredging. This will limit our potential targets significantly.
Earliest Start Date: 1/1/2021 Multi-Ship Op: No

Repeating Cruise?

No Interval:   # of Cruises:  

Description of Repeating cruise requirements: N/A
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
We have chosen the Kilo Moana, as our experience on-board suggests that it functions well for mapping and dredging in these waters. The Revelle has more significant bubble sweep problems with its multibeam in higher seastates, and it is currently scheduled to be in the southern ocean during our preferred time of year. Only one cruise has been carried out on R/V Sally Ride (that we know of) that included dredging, and we therefore prefer a more thoroughly tested platform for a dredging-focused cruise.

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

Japan, Marshall Islands, US EEZ
 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?

Comments about foreign clearance requirements or
description of any other special permitting requirements
(e.g., MMPA, ESA, IHA, Marine Sanctuaries, etc.)
We will be working in the waters of the "Northern Mariana Islands and Guam", the Japanese waters around Marcus Island, and international waters. We will be close to the boundary of the Marshall Islands, and if no suitable dredge site is present outside of its EEZ, we may have to dredge inside Marshalese waters.
Port Calls

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops
Proposed cruise track is most efficient if returning to starting port. Alternate ports near the work area are far away and logistically challenging (for shipping supplies or samples; e.g., Marshall Islands).

Explanation of Science Party Requirements and Technician Requirements This is a dredging and multibeam mapping cruise, thus we request two experienced dredging technicians for around the clock dredging operations. The rest of the science crew will consist of the following total from 3 institution: 7 undergraduates, 2 graduate, 1 post-doc, 4 co-PIs (including chief sci), 3 early career researchers, for a total of 17 (+ 2 marine technicians provided by operator). We need a large science crew to process, describe and pack the dredge samples.

requirements that could affect choice
of ship in scheduling.

We need a ship that has good multibeam performance under sometimes rough sea conditions in order to identify dredge targets. Dredging will also be challenging in the same weather conditions, so we request spare equipment including multiple dredges and pingers in order to successfully finish this dredging cruise. We also will collect magnetics. In addition, we will need some space to store the dredged rock samples (likely 3-5 pallets worth).
