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 Title: Collaborative Research: Experiment on Internal Tide Scattering Project Status: Submitted
Principal Investigator: T. M. Shaun Johnston, SIO Project Institution: SIO
Project ID: 101404 Version #: 3
Date Submitted: 1/29/2008 1:45:00 PM Created By: T. M. Shaun Johnston
Date Last Modified: 4/28/2009 1:26:00 PM URI Serial #: None
Funding Agencies: NSF/OCE/PO - 0824954 - Funded
Summary of Field Work: 3 cruises to the Line Islands Ridge will examine internal tide scattering from topography. Cruise 1 will deploy 3 moorings each equipped with 2 McLane Moored Profilers for 50 days. We will then occupy 19 CTD/LADCP/microstructure stations for 25 hours each and make at least 8 casts. The rosette will be equipped with the ship's CTD, ship's ancillary sensors, upward and downward looking ADCPs, and an internally recording micrconductivity instrument powered by the CTD. No bottles are needed. Also an untethered microstructure instrument will be deployed and recovered every 6 hours in between CTD profiles about 1-2 miles from the CTD station. Cruise 2 will recover and redeploy the moorings for 100 days. Cruise 3 will recover the moorings. Transit from Honolulu is about 3 days in each direction. Cruises 1-3 are requested to be 32, 12, and 12 days. Cruise 1 mooring deployments should be completed several days before the spring tide. (More details can be provided during scheduling.)
Summary of Facility Requirements: - Ship's CTD and ancillary instruments without bottles
- Starboard crane for recovery and deployment of untethered microstructure instrument
- TSE mooring winch for mooring work
- 50 and 140 kHz Doppler sonar on R/V Revelle
- multibeam for bathymetry survey of mooring sites
Summary of other requirements and comments: R/V Revelle is requested for Cruises 1-3 because of the 50 and 140 kHz Doppler sonars excellent current shear measurements. It is especially important for Cruise 1.

Program start deferred to 2010 and separate cruise requests created for each cruise. Need to verify what the earliest start date in 2010 can be given that the program has been deferred [jmp - 4/28/09]

Repeating Cruise?
(within same year)
Yes Interval: 50, 100 days # of Cruises: 3

Description of Repeating cruise requirements: Cruise 1 is 32 days. The first mooring is deployed on day 4. Moored profiler batteries last 50 days.

Cruise 2 is 12 days and begins 54 days after Cruise 1 begins. The first mooring is deployed on day 4 of cruise 2. Moored profiler batteries last 100 days. Moorings will be recovered and redeployed.

Cruise 3 begins 104 days after Cruise 2 begins. Moorings are recovered.

1 full day of loading and unloading for each cruise is needed.
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
Revelle is requested for the 140 and 50 kHz Doppler sonars because of their excellent resolution of current shear. This is especially important for Cruise 1.
Work Area for Cruise

requirements that could affect choice
of ship in scheduling.

We will be deploying moorings and need to survey sites for their deployment on cruise 1. Dynamic positioning would be useful for CTD profiling, but is not essential.
