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. |

Explanation of Science Party Requirements and Technician Requirements |
We will test an aperture of the full hydrophone array. We will need assistance from crew to crane lift the winch and array system on board the research vessel.
We will tow the array roughly 300 m behind the research vessel and need assistance from the crew in deploying and recovering the array.
We will also acquire data from the shipboard CTD/XBT probes and echosounders, and will require assistance from the Science Tech for this data collection. |
