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 Sound Project Status: Submitted
Principal Investigator: David R. Barclay, SIO Project Institution: SIO
Project ID: 101829 Version #: 2
Date Submitted: 1/9/2009 5:38:00 PM Created By: David R. Barclay

Funding Agencies: INST/UCSD/SIO - NONE - Funded
Summary of Field Work: Deep Sound is a high-bandwidth acoustic recording, free-falling system designed to profile ambient noise from the surface to depths of 9 km. The recording platform is autonomous and descends under gravity at 1 m/s to its pre-programmed maximum depth, where a burn-wire releases a weight, permitting the system to return to the surface under its own buoyancy. Two hydrophones are mounted at half meter vertical spacing allowing the noise spectrum and vertical coherence (directionality) to be obtained over four decades of frequency (10 Hz – 100 kHz). The acoustic recordings are made continuously as the instrument descends and ascends along with measurements of sound speed and depth. The system’s low power and large data storage capability allows round trips to the deepest trenches of the ocean. Alternative modes of operation include the system’s ability to act as a synthetic aperture, or to descend to the seabed, record and return to the surface at a later time. A 'Deep Sound Mark II' is currently under development, which uses four hydrophones for measuring the vertical and horizontal properties of the ambient noise field.

The next stage of this research is to deploy the instrument in the field and record data in a deep ocean trench. From this data set, the primary goals of the experiment will be accomplished; to measure spatial coherence (directionality), intensity, attenuation and absorption over a large range of depths and a large bandwidth. Secondary goals of this research are the measurement of environmental parameters through ambient noise and exploiting the free falling nature of Deep Sound to perform synthetic aperture processing.
Summary of Facility Requirements: The facility requirements on board the Melville will be minimal. Storage space for both instruments will be required, each with a foot print of ~ 1 m^2. Deployment can either be done via a crane, A frame or small boat. On recovery, a telecommunications link in order to retrieve GPS co-ordinates broadcast by the instrument is required. An RF direction finder is also required for recovery. The physical retrieval of Deep Sound could be done either via a small boat or by grappling a tether or netting the instrument itself and hauling it on board using a crane or A frame.
During the deployment, the ships only requirement would be to generate the minimum amount of operation noise possible.
