A numerical procedure is presented for analysis of backscatter spectra recorded by an atmospheric Doppler lidar experiment. The recorded spectra are modelled by an analytic function of five parameters.
Spatio-temporal variability of zooplankton community structure off east Antarctica (90 to 160°E) was studied from 1988 to 1996 based on samples collected by the Japanese icebreaker Shirase. Three community groups with distinctive species compositions were obtained by cluster analysis.
Global thunderstorm activity maintains a variable potential difference … of the order of 250 kV between the quasi-equipotentials of the lower … reaches of the ionosphere and the Earth.
The international Antarctic science community collects an amazing amount of information about wildlife. Traditionally, this information has gone into field notebooks and more recently, software such as Excel®.
The abundance of small faecal pellets is high in marine waters. Little is known, however, about the processes governing their production and fate in the water column. We investigated faecal pellet production and flux in relation to the phytoplankton and copepod assemblages present in Ellis Fjord…
