Acoustic observations of finescale zooplankton distributions in the ...

In summary, we found that zooplankton were distributed in finescale, intense, and persistent vertical layers. ... These results indicate that plankton ...

Acoustic backscatter observations of zooplankton abundance and ...

Acoustic backscatter data were compared with physical and biological data collected during leg 2 of the PRIME cruise in the northeastern Atlantic during July ...

Acoustic observations of zooplankton in lakes using a Doppler ...

To correlate ADCP backscatter estimates against zooplankton concentration, a calibration experiment was set up with ADCP measurements and simulta-. Acoustic ...

Acoustic observations of nekton and zooplankton along the ...

Observations of fish and squid (nekton) and crustacean and gelatinous animals (zooplankton) at the shelf break using active acoustic systems ...

Acoustic observations of zooplankton in lakes using a Doppler ...

Acoustic Doppler current profilers have been successfully used in lakes to capture diel migration behavior in larger planktonic species such as the insect ...

Acoustic observations of zooplankton in lakes using a Doppler ...

1. In this paper we test the usefulness of acoustic backscatter measurements from a 614 kHz Acoustic Doppler Current Profiler (ADCP) for the qualitative and ...

Acoustic detection of zooplankton diel vertical migration behaviors ...

In situ imaging and net observations showed that the most likely acoustically observed migrating zooplankton were chaetognaths, shrimp ( ...

Acoustic Doppler current profiler observations of migration ... - OS

Several limitations of the ADCP and auxiliary data should be carefully considered. Sv is a proxy for zooplankton biomass and when integrated along the ...

Acoustic classification of zooplankton - Oxford Academic

Abstract. Accurate acoustic characterization of zooplankton species is essential if reliable estimates of zooplankton biomass are to be made from acoustic.

Acoustic Instrumentation for the Observation of Biomass and Size ...

OBJECTIVES. It is essential to continue improving the acoustic technology for observing zooplankton because its power is in the extended in time primarily and ...

contrast, h (ratio of speed of sound in the two media; c₁/c) are both nearly unity. Because of this, backscatter from zooplankton is generally very small ...

Classification of live, untethered zooplankton from observations of ...

A broadband, multiple-angle acoustic array was used to classify millimeter to centimeter sized live zooplankton in a laboratory tank.

Acoustic observations of plankton and turbulence in a tidally ... - ICES

Theoretical, laboratory, and field work have shown that turbulence can affect the feeding success and growth of zooplankton, both positively and negatively.

Acoustic measurements of zooplankton distributions in the sea

Correlations produced with the truncated fluid-sphere model values were slightly higher than correlations gener- ated by data from the other two models, ...

Acoustic observations of zooplankton distribution in Saanich Inlet ...

A biological front at the mouth of Saanich Inlet results in higher rates of primary productivity at the inlet mouth relative to the head ...

Vertical structure characterization of acoustically detected ... - Frontiers

Acoustic data were processed to extract three specific scattering structures linked to Euphausia superba, Euphausia crystallorophias and the so called Sound- ...

Bioacoustical oceanography at high frequencies

The critical material properties in zooplank- ton acoustics are the ... data on the acoustic and zooplankton variability at that site and as a test ...

Simultaneous acoustic observations of turbulence and zooplankton

Acoustics is commonly used to survey zooplankton abundance and recent studies have shown that stratified turbulence can also be a significant ...

Acoustically-Inferred Zooplankton Distribution in Relation to ...

We have examined the distribution of zooplankton in relation to hydrography in and around Marguerite Bay , using acoustic backscattering intensity (43, 120, 200 ...

Representative range of acoustic point source measurements in the ...

In this study we use concurrent mobile and stationary acoustic data to characterize spatial variability in fish and zooplankton densities and to ...
