Surf-generated noise signatures: A comparison of plunging and spilling breakers
TL;DR: Range-time signatures of plunging breakers indicate a burst of acoustic energy while spilling breakers' signatures depict sound being generated over a longer time period with the source region moving with the breaking surface wave.

Effects of sea-surface conditions on passive fathometry and bottom characterization
Steven L. Means,Martin Siderius +1 more
TL;DR: To quantitatively study the dependency between processing and environmental factors such as wind speed, measurements were made using a fixed hydrophone array while simultaneously characterizing the environment to quantify the dependency of passive fathometer results on wind speeds, wave conditions, and averaging times.
Computations of bubble formation and pulsations generated by impacting cylindrical water jets
TL;DR: In this article, a computational model using a generalized theory of hydrodynamics designed to rigorously treat liquid collisions is described, which provides details not only of the initial formation of the air-entrained bubble at the time of the cavity collapse, but also the subsequent pulsations of this bubble until it rises back to the free surface.

Ambient noise forecasting with a large acoustic array in a complex shallow water environment.
TL;DR: The assertion is that noise forecasting can be improved with a priori knowledge of source positions coupled with the ability to resolve closely separated sources in bearing.

Environmental effects on passive fathometry and bottom characterization
Steven L. Means,Martin Siderius +1 more
TL;DR: In this article, Siderius, Harrison, and Porter developed a method, based on the Fourier synthesis of the cross-spectral density from nearby positions, to exploit the oceans' coherent ambient noise field due to breaking waves to make measurements of the bottom and subbottom properties.
