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. |

Short Description of Op Area
for use in schedules: |
Gulf of Maine |
Description of Op Area: |
Gulf of Maine is in the US East coast and is close to Boston. Marine mammals are abundant in the Gulf of Maine in Sep/Oct. We will test our hydrophone array system by recording the whale vocalizations that span a wide range of frequencies. |

Explanation of Science Party Requirements and Technician Requirements |
Science party will include PI and graduate and undergraduate students from Northeastern University and MIT.
The prototype array we are bringing on board comprises of a winch and a 100 m tow cable with hydrophone sensors. We will tow the array behind the ship at 4 knots. Help is needed from the crew to assist us in deploying and retrieving the array.
In addition to our towed array data, we will also collect data with shipboard CTD/XBT and echosounders. We will require a ship Science Tech to train us in operating the CTD/XBT and echosounders. |
