The visco-thermal absorption of sound by suspended particulate matter can be reliably measured using a reverberation technique. This absorption may have an adverse effect on the performance of sonars operating at 50–300 kHz in coastal waters where

Many shallow‐water acoustic applications (e.g., naval mine‐hunting sonars, acoustic Doppler current profilers) involve devices operating in the frequency range 50–300 kHz over path lengths up to several hundred meters. At these ranges and frequ

This study has examined the effects of frictional formulations in numerical ocean models on simulated acoustic fields. Starting from the same initial state of a perturbation to a simple linear front, comparisons are made of numerically simulated fron

The position of the Iceland-Faeroes Front is closely related to the submarine ridge connecting Iceland with the Faeroes. The ridge and the front inhibit mixing of the warmer salty North Atlantic water with the cooler fresher water to the north. Excur

A three‐dimensional (3‐D) numerical ocean model has been used to study sound propagation through an ocean front. The model has been used to provide environmental data for input to a range‐dependent acoustic model to study the effect of eddies t

The use of a 3-D numerical ocean model to simulate mesoscale frontal and eddy environments for the input to range dependent acoustic models is described. The technique has been used to investigate the sensitivity of acoustic predictions to changes in

The measurement of sediment transport rates in the sea remains one of the most elusive goals for oceanographers, sedimentologists and coastal engineers. Such measurements are required to test and validate sediment transport theories. Progress in this
