[email protected]. Effects of ocean thermocline variability on noncoherent underwater acoustic communications ͒ Martin Siderius,a Michael B. Porter, Paul Hursky, Vincent McDonald, and the KauaiEx Group HLS Research Corporation, 12730 High Bluff Drive, San Diego, California 92130 ͑Received 16 December 2005; revised 14 December 2006; accepted 30 December 2006͒ The performance of acoustic modems in the ocean is strongly affected by the ocean environment. A storm can drive up the ambient noise levels, eliminate a thermocline by wind mixing, and whip up violent waves and thereby break up the acoustic mirror formed by the ocean surface. The combined effects of these and other processes on modem performance are not well understood.
