Postweaning behaviour in pups of the southern elephant seal (Mirounga leonina) on South Georgia
Read more of: Postweaning behaviour in pups of the southern elephant seal (Mirounga leonina) on South GeorgiaAfter weaning, southern elephant seal pups (Mirounga leonina) fast for 3 – 8 weeks, for largely unknown reasons. During the postweaning fast we observed daytime behaviour and movements of pups […]

Forward Modeling of the Internal Layers in Radio Echo Sounding Using Electrical and Density Measurements from Ice Cores
Read more of: Forward Modeling of the Internal Layers in Radio Echo Sounding Using Electrical and Density Measurements from Ice CoresThe measured density and conductivity of a 181 m ice core are used to calculate a profile of complex reflection coefficients. It is confirmed that the amplitude reflection coefficients due […]

Aqueous geochemistry as an indicator of chemical weathering on southeastern Alexander Island, Antarctica1
Read more of: Aqueous geochemistry as an indicator of chemical weathering on southeastern Alexander Island, Antarctica1Chemical alteration of rock in the Antarctic is considered to be less dominant than physical weathering processes. The research presented in this discussion represents investigations to determine the extent of […]

Seasonality in Antarctic airborne fungal spores
Read more of: Seasonality in Antarctic airborne fungal sporesAirborne fungal spores were monitored over periods of up to 131/2 months at three sites on Signy Island in the maritime Antarctic. Fungal spore concentrations in the air were much […]

Surface wind fields of Antarctic mesocyclones derived from ERS 1 scatterometer data
Read more of: Surface wind fields of Antarctic mesocyclones derived from ERS 1 scatterometer dataThe effectiveness of ERS 1 scatterometer data as a tool for studying the wind fields of Antarctic mesocyclones is analyzed by using 1 year’s observations of these systems derived from […]
