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: The high-resolution horizontal structure of ocean currents and buoyancy off the coast of southern California Project Status: Submitted
Principal Investigator: Saulo M. Soares, SIO Project Institution: SIO
Project ID: 106674 Version #: 2
Date Submitted: 12/2/2019 7:27:00 PM Created By: Saulo M. Soares
Date Last Modified: 7/21/2020 11:26:00 PM URI Serial #: None
Funding Agencies: INST/UCSD/SIO - NONE - Funded
Summary of Field Work: Characterization of the horizontal structure of upper ocean currents and buoyancy in the deep waters off southern California with high resolution measurements. The primary goal is to sample the fields associated with internal inertia gravity waves.

This work will consist of fully underway sampling to be conducted off point Conception in southern California using a towed underway CTD package (uCTD) and shipboard acoustic Doppler current profiler (ADCP). Sampling will occur along a specified track that allows detection, in a statistical sense, of directionality in the internal wave field; sampling along the tracks will be 24 hr continuous tow-yo operation. The high-resolution work will be accomplished with 3 repeated surveys of the predefined sampling tracks, either in a single 11 days cruise or spread in 3 shorter duration cruises. The cruise or cruises will ideally be scheduled for summer (June-September) to avoid very deep mixed layers that would prevent underway sensors to reach into the thermocline.
Summary of Facility Requirements: All available hull mounted ADCPs; deck space near the stern to set up uCTD whinch and a working station for uCTD watchstanders; space on stern gunwale to mount uCTD stand.

Requested Ship, Operating Days and Dates
Year: 2020 Ship/Facility: Sally Ride
Optimum Start Date: 6/16/2020 Dates to Avoid: Must avoid mid September onward as the uCTD, the primary instrument, will not be available. Should also avoid winter and early spring days (Jan 1 to Mar 31) because the instruments may not reach target depth (thermocline).
Earliest Start Date: 4/6/2020 Multi-Ship Op: No
