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: Platform Centric ASW Processing with Through-the-Sensor Data Assimilation and Fusion Project Status: Submitted
Principal Investigator: William S. Hodgkiss, SIO Project Institution: SIO
Project ID: 106360 Version #: 2
Date Submitted: 1/29/2019 2:58:00 PM Created By: William S. Hodgkiss
Date Last Modified: 5/14/2019 4:15:00 PM URI Serial #: None
Funding Agencies: NAVY/ONR - NONE - Funded
Summary of Field Work: Observations of mid-frequency signal propagation and ambient noise using a buoy-tethered acoustic array. Simultaneous observations of the local physical oceanography and ocean surface wave field.
Summary of Facility Requirements: Large A-frame and ample deck space for layout of array hardware, 3 buoys, 4 Wirewalkers, 2 wave gliders and 1-2 winches. CTD, ADCP, multi-beam, subbottom profiler, and WAMOS wave monitoring system will be used along with the HDSS Doppler sonar system.

Requested Ship, Operating Days and Dates
Year: 2021 Ship/Facility: Roger Revelle
Optimum Start Date: 4/1/2021 Dates to Avoid: Weather is a consideration since deployment/recovery of the array hardware cannot be done in significant seas.
Earliest Start Date: 3/1/2021 Multi-Ship Op: No
Latest Start Date: 5/1/2021 Other Ship(s): N/A

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

Description of Repeating cruise requirements: N/A
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
Roger Revelle has the HDSS Doppler sonar system installed. Sally Ride previously has been used to deploy the acoustic array hardware. Window of requested dates due to weather considerations.
Work Area for Cruise
Short Description of Op Area
for use in schedules:
Philippine Sea
Description of Op Area: Approx 200 nm WNW of Apra Harbor, Guam. Approximate location is 14-20N, 141-25E.

Foreign Clearance and Permitting Requirements
Foreign Clearance Required? No 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)?
Yes If yes, have you applied for the necessary permits through your export control office? No
 Questions about ITAR/EAR regulations?
