First in situ temperature measurements at the Antarctic summer mesopause
Read more of: First in situ temperature measurements at the Antarctic summer mesopauseThe Arctic summer mesopause at ∼88 km is the coldest-known place (∼130 K) in the terrestrial atmosphere and is ∼60 K colder in summer than winter. Indirect evidence has suggested […]

Possible evidence for Late Cretaceous off-axis volcanism in the outer James Ross Basin
Read more of: Possible evidence for Late Cretaceous off-axis volcanism in the outer James Ross BasinA prominent volcaniclastic channel sandstone deposited by a landward-flowing sediment gravity flow is described from the Maastrichtian of Snow Hill Island in the northern Larsen Basin. The characteristics of this […]

A Lower Cretaceous clastic slope succession, Livingston Island, Antarctica: sand-body characteristics, depositional processes and implications for slope apron depositional models
Read more of: A Lower Cretaceous clastic slope succession, Livingston Island, Antarctica: sand-body characteristics, depositional processes and implications for slope apron depositional modelsThe early Cretaceous fill of the forearc/intra-arc Byers Basin includes a 600- to 900-m-thick interval of marine slope apron deposits, the President Beaches Formation. This is a predominantly argillaceous succession […]

An assessment of three automatic depression tracking schemes
Read more of: An assessment of three automatic depression tracking schemesThe performance of three automatic depression tracking schemes developed by Terry & Atlas (1996), Murray & Simmonds (1991a) and Konig et al. (1993) when applied over one month are assessed. […]

Antarctic aerosol and snowfall chemistry: implications for deep Antarctic ice-core chemistry
Read more of: Antarctic aerosol and snowfall chemistry: implications for deep Antarctic ice-core chemistryIn this paper we first summarise major findings of recent atmospheric studies of nitrogen and sulphur species present in the boundary layer of coastal Antarctic regions. We then discuss the […]

Stable isotopes document inter- and intra-specific variation in feeding ecology of nine large southern Procellariiformes
Read more of: Stable isotopes document inter- and intra-specific variation in feeding ecology of nine large southern ProcellariiformesInvestigating the foraging ecology of seabirds is especially challenging given their wide-ranging movements and the practical difficulties of obtaining unbiased information on their feeding behavior. Despite the development of animal-borne […]

Formation of RADARSAT backscatter feature and undulating firn stratigraphy at an ice-stream margin
Read more of: Formation of RADARSAT backscatter feature and undulating firn stratigraphy at an ice-stream marginOn RADARSAT imagery, the southern margin of the onset zone of Bindschadler Ice Stream, West Antarctica, manifests a multi-banded feature, with brightness varying across the bands and oscillating along each […]

The terrestrial and freshwater invertebrate biodiversity of the archipelagoes of the Barents Sea; Svalbard, Franz Josef Land and Novaya Zemlya
Read more of: The terrestrial and freshwater invertebrate biodiversity of the archipelagoes of the Barents Sea; Svalbard, Franz Josef Land and Novaya ZemlyaArctic terrestrial ecosystems are generally considered to be species poor, fragile and often isolated. Nonetheless, their intricate complexity, especially that of the invertebrate component, is beginning to emerge. Attention has […]
