Marine depth sounding apparatus

The Journal of the Acoustical Society of America, 1981
A marine depth sounding apparatus including a floatable housing carrying a sonic transducer for emitting sound waves toward the bottom of a body of water and for detecting the reflections of such sound waves, and a sound transmitter for emitting an audible signal when the information provided by the sonic transducer indicates that the depth of the ...

Geomagnetic Depth Sounding (GDS)

2020
In this chapter, the geophysical exploration tools record only natural time-varying magnetic fields of the Earth are included. Geomagnetic Depth Sounding (GDS), Magnetovariational Sounding (MVS) and Magnetometer Array Studies (MA) are the principal topics of this chapter.

Communicative depth: Soundings from developmental psychopathology

Infant Behavior and Development, 2007
My aim in this paper is to consider what it means to engage and communicate with another person. I do so by adopting the approach of developmental psychopathology, and compare and contrast the structure of communication that is manifest by typically developing infants on the one hand, and by children and adolescents with autism on the other.

Laser Airborne Depth Sounding in Australia

Journal of Navigation, 1986
Australia, with its large continental shelf, requires faster and more economic methods of conducting hydrographic survey. Backed by the Royal Australian Navy an experimental programme to investigate airborne laser methods was commenced in the mid 1970s and completed in 1984.

Sound and stereoscopic 3D: Examining the effects of sound on depth perception in stereoscopic 3D

2016 7th International Conference on Information, Intelligence, Systems & Applications (IISA), 2016
Prior work focusing on 2D visuals primarily suggests that sound has a significant impact on visual perception. However, little work has considered what, if any, effects sound, including its spatial positioning and the addition of various auditory effects, have on our perception of stereoscopic 3D (S3D) imagery.

Depth perception by means of ambient sounds in a small mammal

Experientia, 1982
Golden hamsters placed on a jumping stand from which they can descend onto a shallow or deep landing platform prefer to descend on to the shallow platform, even when tested under IR-light without tactile cues. This preference disappears for subjects with plugged ears.

Depth of investigation in electromagnetic sounding methods

Geophysics, 1989
Abstract The time or frequency at which the electromagnetic (EM) response of a buried inhomogeneity can first be measured is determined by its depth of burial and the average conductivity of the overlying section; it is relatively independent of the type of source or receiver and their separation.

Sounding the depths at the confluence of numerosity and language

Linguistics Vanguard, 2014
AbstractResearchers in a variety of disciplines are currently exploring how number words and other culturally variant symbols for quantities enable and enhance numerical cognition. In this article I survey the ways in which fieldwork among Amazonian languages is helping to elucidate the relationship between numerical cognition and language. I highlight

Analysis of geomagnetic depth sounding data

2010
The electromagnetic induction problem is non-linear, and thus is very difficult to solve for all but the simplest symmetries. Because of this, quantitative modelling of the conductivity structure from geomagnetic depth sounding data is expensive and time consuming, and the possibility that the anomaly is produced by channelling of regionally induced ...
