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: Deep-ocean Assessment and Reporting of Tsunamis (DART) Service of Stations 46412 and 43412 Project Status: Submitted
Principal Investigator: Jeff Jenner, NOAA_NDBC Project Institution: NOAA_NDBC
Project ID: 103127 Version #: 1
Date Submitted: 9/22/2011 4:13:00 PM Created By: Jeff Jenner
Date Last Modified: 10/11/2011 3:36:00 PM URI Serial #: None
Funding Agencies: NOAA/NWS/NDBC - NONE - Funded
Summary of Field Work: The ship will transit to DART station 43412, located approximately 230 nautical miles southwest of Manzanillo, Mexico (16°2'1" N 107°0'4" W). Upon arrival at the station, the ship's survey technician will perform a full depth CTD cast. Data is only required on the downcast, and the CTD can be lowered at maximum allowable speed. Required measurements are depth, salinity, and speed of sound. The survey tech will use the sound velocity data and the ship's echosounder to calculate water depth. After the CTD cast, NOAA techs will attempt to contact the existing Bottom Pressure Recorder (BPR) and activate the acoustic release. This was attempted on May 22, 2011, with no success. If BPR release is successful, the ship's deck crew and NOAA techs will recover the BPR and floats. The ship's deck crew and NOAA techs will then deploy the buoy on a new mooring, then deploy the BPR. The ship will remain on station for six hours after the BPR has settled on the sea floor to ensure that the system is operating properly.

When released from station 43412, the ship will transit approximately 1,230 nautical miles northwest to station 46412, which is located 170 nautical miles west of San Diego (32°27'26" N 120°33'38" W). NOAA techs will send a signal to the BPR acoustic release and will recover the BPR and floats when they surface. NOAA techs and the ship's deck personnel will then bring the existing buoy on board and exchange it for a new buoy using the same mooring. Techs will deploy the new buoy, then deploy the new BPR. The ship will remain on station for six hours after the BPR has settled on the sea floor to ensure that the system is operating properly. During this time, the ship's survey technician will perform a full depth CTD cast. Data is only required on the downcast, and the CTD can be lowered at maximum allowable speed. Required measurements are depth, salinity, and speed of sound. After being released from station 43412, the ship can transit to port.

When the ship gets within 50 nautical miles of each station, the ship's survey technician will activate the Acoustic Doppler Current Profiler and continue its operation until the work is done at the station and the ship is 50 nautical miles away from the station. A 75 kHz ADCP is required, though a 38 kHz ADCP is desired. The ship's echosounder and transducer system shall be rated for a depth of at least 4,000 meters. The depth at station 43412 is 3,245m and at 46412 is 3,717m.

The ship will leave port on November 30, 2011 and return on December 13, 2011. Equipment delivery and ship loading will be November 28-29 and demobilization will be on December 14. NOAA's gear will consist of two 3,500 pound DART buoys, two bottom pressure recorders (each with an anchor and string of glass ball floats), two 6'x6'x6' aluminum mooring line boxes, two 3,000 pound anchors, 12 spools of 3/4" nylon line, and assorted tools and supplies in small shipping containers.
Summary of Facility Requirements: R/V New Horizon
Crane for retrieving and deploying buoys (3,500 pounds minimum)
Survey tech, crane operator, and deck crew
CTD (full ocean depth, 4,000m)
Echosounder (4000m depth)
ADCP (75 kHz required, 38 kHz desired)
Summary of other requirements and comments: Project Amount is for 3.5 days. This is in addition to the 10.5 day credit that NOAA NDBC has with SIO. The Project Amount does not include the UNOLS administrative cost of $5775.45, and assumes NOAA will not be charged for dockside mobilization/demobilization days (November 28-29 and December 14). This is subject to availability of funds and approval of ISA (submitted to NOAA OMAO for review 9/21/11).
