The past 30 years have seen a growing interest in underwater acoustic communications
because of its applications in marine research, oceanography, marine commercial …

The past three decades have seen a growing interest in underwater acoustic
communications. Continued research over the years has resulted in improved performance …

Shallow water acoustics (SWA), the study of how low and medium frequency sound
propagates and scatters on the continental shelves of the worlds oceans, has both technical …

The oceans remain the least explored frontiers on this planet and many oceanic and
maritime applications seem relatively slow in exploiting the state-of-the-art info …

Sound at 85 to 450 Hz propagating in approximately 80-m depth water from fixed sources to
a joint horizontal/vertical line array (HLA/VLA) is analyzed. The data are from a continental …

Simultaneous measurements of acoustic wave transmissions and a nonlinear internal wave
packet approaching an along-shelf acoustic path during the Shallow Water 2006 experiment …

During a 12-h period in the 2006 Shallow Water Experiment (SW06), binary phase shift
keying (BPSK) signals at the carrier frequencies of 813 and 1627 Hz were propagated over …

Fluctuations of sound intensity in the presence of moving nonlinear internal waves (NIWs)
are studied. Prior works revealed the existence of peaks in the spectrum of these fluctuations …

Anomalously large, transient fluctuations of acoustical noise intensity, up to 4–5 orders of
magnitude above the background, were observed with single-hydrophone receiver units …

While many results have been intuited from numerical simulation studies, the precise
connections between shallow-water acoustic variability and the space-time scales of …
