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: Midwater trawl sampling in support of CalCOFI acoustic surveys Project Status: Submitted
Principal Investigator: Tony Koslow, SIO Project Institution: SIO
Project ID: 102570 Version #: 1
Date Submitted: 7/27/2010 7:38:00 PM Created By: Tony Koslow
Date Last Modified: 7/27/2010 7:38:00 PM URI Serial #: None
Funding Agencies: INST/UCSD/SIO - NONE - Funded
Summary of Field Work: Stratified midwater trawl sampling will be carried out with an MOHT midwater trawl (5 m^2 mouth opening with depressor and rigid frame) during the summer CalCOFI cruise. Over the 24 hr period of available ship time, four hours will be devoted to acoustic transducer calibration at the end of the cruise, and 20 hr will be spread out over the duration of the cruise to enable sampling on the six core CalCOFI transects. Approximately 14 shallow tows to 200 m depth are planned for the night-time period (1 hr duration for each tow, total operation) and 3 deep tows to about 500 m depth during daytime (approximately 2 hr duration for total tow operation).
Summary of Facility Requirements: Stern A frame and winch.
Summary of other requirements and comments: The MOHT trawl was successfully deployed on a previous CalCOFI cruise on New Horizon. It requires 5 personnel for deployment and retrieval, and several of the scientists on board have had experience with the gear. Vessel speed during deployment and retrieval should be about 1-2 kt and about 4 kt during the tow operation. The Chief Scientist is familiar with the gear and has a list of preferred station operations. The gear should be towed while en route between stations to minimize the impact on available ship time.

provided by ship operator:
(include in science party total)
Explanation of Science Party Requirements and Technician Requirements Jian Liu and Amanda Netburn will be primarily responsible for the gear and samples. Deployment and retrieval require 5 persons plus a winch operator and control from the bridge. The back-deck operation has been carried out by the CalCOFI technicians. One scientist will be required afterward for sample processing.
