Polar patches – outstanding issues
Historically, the term polar patch was used to describe isolated regions of enhanced 630 nm emission observed in the polar cap. In recent years, signatures from other instruments, such as […]

Ionospheric signatures of magnetopause pocesses
Read more of: Ionospheric signatures of magnetopause pocessesWhilst it is well-accepted that short-duration changes to the Interplanetary Magnetic Field (IMF) and solar wind cause high-latitude ionospheric transients observed by magnetic, optical and radar techniques, a coherent explanation […]

Determining the sex of Antarctic krill Euphausia superba using carapace measurements
Read more of: Determining the sex of Antarctic krill Euphausia superba using carapace measurementsA discriminant function using simple carapace measurements corretly determined the sex of 87% of male and 89% of female Antarctic krill Euphausia superba. This facilitated the use of sex-specific regression […]

Early evolution of the Proto-Andean margin of South America
Read more of: Early evolution of the Proto-Andean margin of South AmericaFrom a detailed study of a 500 km transect in the Sierras Pampeanas, central-west Argentina, two pre-Silurian tectono-magmatic episodes are recognized and defined, each culminating in micro-continental collisions against the […]

Large-scale submarine landslides, channel and gully systems on the southern Weddell Sea margin, Antarctica
Read more of: Large-scale submarine landslides, channel and gully systems on the southern Weddell Sea margin, AntarcticaNew multibeam bathymetric data from the southeastern Weddell Sea show significant differences in surface morphology of the outer continental shelf and slope between two adjacent cross-shelf troughs. These are the […]
