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: Development of a large-aperture coherent hydrophone array hardware system, and data
processing and analysis software system for instantaneous wide-area passive acoustic
monitoring of ocean environments
Project Status: Submitted
Principal Investigator: Purnima R. Makris, Nthest U Project Institution: Nthest U
Project ID: 105692 Version #: 1
Date Submitted: 2/11/2017 11:26:00 AM Created By: Purnima R. Makris
Date Last Modified: 9/12/2018 11:04:00 AM URI Serial #: None
Funding Agencies: NSF/OCE/OTIC - 1736749 - Funded
Summary of Field Work: Two Intermediate and one final testing of coherent hydrophone array hardware.

First test : Prototype array testing for confirming hardware and software parameters

Second test : Intermediate hardware and software testing of a subaperture of the full system. We will complete construction of one subaperture containing 64 hydrophones and the auxillary sensors prior to this sea test.

3rd test: Final hardware and software testing with all four subapertures and functionality of the full system. We will complete construction of all four subapertures containing 160 hydrophones in total and all auxillary sensors prior to this sea test.
Summary of Facility Requirements: CTD/XBT and multibeam/echosounder data will be collected. Will require crane to lift the full array system during mob and demob.

Science Party
Chief Scientist: Purnima R. Makris, Nthest U
# in Science Party 10 # of different science teams 1 # Marine Technicians to be
provided by ship operator:
(include in science party total)
Explanation of Science Party Requirements and Technician Requirements We will have a minimum of 10 in our science party for the first cruise on RV Langseth to ensure the coherent hydrophone array is operating all 24 hours.

The array will be towed roughly 300 m behind the ship. We need assistance from the crew to deploy and recover the array.

We will collect CTD/XBT and echosounder data, and will require assistance from the ship Science Tech.

We plan to go over with the ship Science Engineer usage of the full POAWRS coherent hydrophone array hardware and data acquisition and analysis software.

requirements that could affect choice
of ship in scheduling.

Our goal is to provide instantaneous wide-area marine mammal monitoring with the full coherent hydrophone array system via POAWRS sensing.

If there are active seismic sources in operation, we will also process the full coherent hydrophone array data to investigate instantaneous wide-area active OAWRS imaging with the seismic transmissions.
