Abstract The hydroacoustic environment of a rapidly warming Arctic Ocean will be impacted by interconnected changes in the physical environment and increased human activity. Previous acoustic calculations will need to be updated to reflect current an

Large-scale, depth-averaged temperatures have been measured by long-range acoustic transmissions in the North Pacific Ocean for the past nine years. Acoustic sources located off central California and north of Kauai transmitted to receivers distribut

The goal of the Ocean Bottom Seismometer Augmentation of the Philippine Sea Experiment (OBSAPS) was to study the coherence and depth dependence of deep-water ambient noise, in the band from 0.03 - 80Hz, and signals, in the band from 50-400Hz. The cru

In the PhilSea09 pilot study two moorings equipped with temperature (T), conductivity (C), and pressure sensors, along with upper ocean ADCP, monitored ocean variability for a month in the Spring. The measurements reveal an energetic and nonlinear mi

Receptions of long‐range acoustic transmissions by deep hydrophone arrays in the Pacific and Atlantic often have ‘‘ray‐like’’ arrivals that occur in the shadow zone of the predicted time front. These ‘‘ray‐like’’ arrivals can fr
