Seabed Characterization Experiment 2017
Abstract
The PI will prepare and deploy two vertical receiving arrays and to carry out acoustic source transmissions during the ONR sponsored Seabed Characterization Experiment. The experiment will take place in the region of New England Mud patch approximately 90 km south of Martha s Vinyard, MA in the April-May 2017 time frame. The proposed effort is split into three parts: (1) Experiment planning, (2) hardware preparation, and (3) participation in SCE17. The PI will participate in an experimental planning meeting scheduled for late FY16. It is anticipated that two (2) 32-element vertical receiver arrays will be prepared for deployment during the experimental phase. The arrays will be configured to collect acoustic data continuously for ~12 days prior to needing servicing. The VLAs will be populated with up to 50 self-recording thermistor devices to collect water column temperature data during the experiment. In addition to the array hardware, source transmission hardware will be prepared for SCE17. The source tow system consists of a 2-channel digital waveform synthesis capability, power amplifiers, winch, tow cable, depth sensor and monitor hydrophone, and transducers. MPL has an ITC-2015 mid-frequency transducer (1.5-4 kHz) and we propose renting a J15-1 transducer for low-frequency transmissions (50 Hz ~ 1 kHz). Data obtained through the equipment prepared and deployed for this project will be combined with other data collected as part of the overall multi-institution, multi-national experiment for analysis leading to a high-resolution description of the shallow water environment in the region of the mud patch.
