In the 1960s tests with a new surface ship sonar indicated that low‐frequency (less than 10 000 Hz) propagation loss was greater than predicted by the existing MgSO4 absorption model. Propagation measurements in the SOFAR channel showed that the an

An experiment was conducted to provide an empirical evaluation of attenuation in sea water in the frequency range of 354–3540 cps. Recordings were made of solar shots detonated every 5 miles along a 500‐mile track. The receiving elements were loc

Lake Superior was chosen as an experimental site to compare sound absorption of freshwater with the results of absorption measurements in seawater. The relaxation-like absorption at 1 kilohertz occurring in seawater is also present in freshwater. A r
The document contains a chronology of the biological and underwater acoustic tests during Project KIWI ONE, between 4 April and 12 June 1972, in areas of the North Atlantic and South Pacific Oceans, the Gulf of Mexico, and the Caribbean Sea. Objectiv

In order to determine the cause of the low‐frequency sound attenuation anomaly in seawater, comparative measurements are being made in freshwater. The Lake Tanganyika experiment (23°C) was conducted to determine the temperature dependency of the a

The trend to lower sonar frequencies following WWII has revealed the existence of two and possibly more regimes of excess attenuation of sound in the oceans. The first of these, identified as a relaxation absorption caused by the MgSO4 content in sea

This paper describes a deep‐water propagation experiment involving the use of both explosive sources and towed sine‐wave projectors in the SOFAR channel of the North Atlantic. It was conducted with the objective of narrowing the list of potential

Sound‐propagation measurements were made along a 100‐mile path in Lake Superior during September 1967 in an area in which water depth exceeded 600 ft. One‐half‐pound TNT charges were detonated at the axis of a sound channel and received on a

Extensive measurements in the Atlantic Ocean (4°C) have shown the attenuation of sound below 10 kHz to be anomalously high. In order to determine the temperature dependency of this anomaly, a similar experiment has been conducted in the warmer water

With the support of the French Navy, a low‐frequency sound propagation experiment was conducted to obtain attenuation coefficients in the Indian Ocean for the frequency range 200&–10 000 Hz. The experiment was conducted along a 500‐km track, wh
