Abstract:

Our work on this grant supported a TACDEV component of the ICEX-18 field program consisting of an ONR funded experiment in cooperation with Arthur B. Baggeroer MIT and Jon Collis Lincoln Laboratoriesemploying acoustic transmissions to submarine towed arrays. Funding supported the technical aspects of integrating, testing, logistical management, field deployment and operation of a JI 5-1 acoustic source at theICEX-18 ice camp n01th of Prudhoe Bay, AK. The source was deployed from a gantry equipped with an electric hoist to a depth of 550 feet through a hole in the ice within a heated shelter. Seven days time at theICEX-18 camp were anticipated including 2 days for mobilizing our equipment approximately 2200 lbs from WHOI to Deadhorse, AK and out to the ICEX-18 ice camp site. We set up our equipment in a hut over a precut 1 by 2 meter hole in the ice. Due to heavy snow and high winds, flight operations were constrained resulting in our arrival on 18 March at the ice camp 4 days later than expected. After brief time for setup and testing we were fortunate to complete 3 of 4 planned 8 hour J15 transmission cycles. We dismantled and packed our equipment and decamped to Deadhorse on 22 March 2018.
