Abstract Ambient seismic noise becomes more and important helpful on assisting velocity model inversion, earthquake detection, ground motion prediction. Based the analysis of continuous data ocean wave height, we find that height winter storms have a controlling factor DF microseismic energy level its frequency extent in time scale. It shows high low accompanied with wide narrow range consisten...

It is an auspicious time for this first-ever ISRR special session on the topic of underwater robotics. Underwater robots are now performing high-resolution acoustic, optical, and physical oceanographic surveys in the deep ocean that previously were considered impractical or infeasible. For example: in 2001 the Argo II underwater robotic vehicle, [1], was employed to discover the first off-axis ...

Snapping shrimp dominate the high frequency soundscape in shallow warm waters. The noises produced by these small creatures are a result of the collapse of cavitation bubbles they produce. During the rapid collapse, the temperatures in the bubble can momentarily reach the surface temperature of the sun, and produce impulsive noise with source levels higher than 190 dB re 1 μPa @ 1m. With millio...

A previous study by the first two authors suggests there is visual information for tone perception: under certain conditions Cantonese speakers are able to identify spoken words as one of six Cantonese words differing only in tone on the basis of lip and face movements at a rate better than chance [1]. Here, non-native (tonal, Thai, and non-tonal, English) language speakers were tested on a dis...

Introduction The current terminology of underwater sound, as documented, for example, by (Urick, 1983), was developed during and after the Second World War (ASA, 1951; Urick, 1967), and has evolved little since then (Jensen et al., 2011). When examined against a modern requirement, with particular attention to the needs of planetary oceanography and underwater noise, this 60-year old terminolog...

This work presents a shallow water ambient noise analysis and modeling effort in the Arabian Sea. Real ambient noise recording at very shallow depths has been analyzed for two environmentally unique periods when the sound velocity profile and the wind conditions present distinct characteristics. Ambient noise data were collected for January and March in the shallow water of Arabian Sea between ...
