Diurnal variations in mean volume backscattering strength of an Antarctic krill (Euphausia superba) patch
A series of acoustic transects and quantitative net hauls was made in a large patch of Antarctic krill ( Euphausia superba ) just north of South Georgia. The krill went through a diurnal pattern of dense swarming in daytime and dispersion after dark. This was accompanied by an 8 dB change in mean vo...

Summary: | A series of acoustic transects and quantitative net hauls was made in a large patch of Antarctic krill ( Euphausia superba ) just north of South Georgia. The krill went through a diurnal pattern of dense swarming in daytime and dispersion after dark. This was accompanied by an 8 dB change in mean volume backscattering strength. |
