The age and stratigraphy of fore-arc megmatism on Alexander Island, Antarctica
Read more of: The age and stratigraphy of fore-arc megmatism on Alexander Island, AntarcticaFore-arc magmatic sequences associated with high Mg number andesite lavas unconformably overlie LeMay Group accretionary complex in Alexander Island. High-resolution 40Ar/39Ar, U–Pb zircon, fission track and K–Ar ages demonstrate that […]

Katabatic wind propagation over the western Ross Sea observed using ERS-1 scatterometer data
Read more of: Katabatic wind propagation over the western Ross Sea observed using ERS-1 scatterometer dataWind fields derived from ERS-1 scatterometer data, acquired over the open water present in the western Ross Sea during the summer season, are used to study the patterns of mesoscale […]

A unifying lithostratigraphy of late Cretaceous–early Tertiary fore-arc volcanic sequences on Alexander Island, Antarctica
Read more of: A unifying lithostratigraphy of late Cretaceous–early Tertiary fore-arc volcanic sequences on Alexander Island, AntarcticaLate Cretaceous–early Tertiary subduction-related fore-arc volcanic rocks are exposed in a north–south linear belt along the length of Alexander Island. The age and tectonic setting of these rocks is well […]

Aspects of the cryobiology of the intertidal Harpacticoid CopepodTigriopus brevicornis(O. F. Müller)
Read more of: Aspects of the cryobiology of the intertidal Harpacticoid CopepodTigriopus brevicornis(O. F. Müller)Cold-resistance studies of marine invertebrates have concentrated on intertidal sedentary organisms, which are often subjected to subzero air temperatures in winter. Mobile rock pool inhabitants have been rarely studied because […]

Maternal investment in Antarctic fur seals: evidence for equality in the sexes?
Read more of: Maternal investment in Antarctic fur seals: evidence for equality in the sexes?Studies of the otariids (fur seals and sea lions), a highly sexually dimorphic group, have provided conflicting evidence of differential maternal expenditure in male and female offspring and, thus, suggestions […]

Subduction influence on magma supply at the East Scotia Ridge
Read more of: Subduction influence on magma supply at the East Scotia RidgeDespite a spreading rate of 65–70 km Ma−1, the East Scotia Ridge has, along most of its length, a form typically associated with slower rates of sea floor spreading. This […]

Two and three component direction-finding computations on whistlers using the Matched Filtering and Parameter Estimation method
Read more of: Two and three component direction-finding computations on whistlers using the Matched Filtering and Parameter Estimation methodA detailed frequency analysis of the azimuthal bearing of ground-observed whistlers by the modified MFPE method (Lichtenberger et al., 1987) based on two and three component digital recordings is presented. […]

The electric field response to the growth phase and expansion phase onset of a small isolated substorm
Read more of: The electric field response to the growth phase and expansion phase onset of a small isolated substormWe capitalise on the very large field of view of the Halley HF radar to provide a comprehensive description of the electric field response to the substorm growth phase and […]
