On the origin of fore-arc basins: new evidence of formation by rifting from the Jurassic of Alexander Island, Antarctica
Read more of: On the origin of fore-arc basins: new evidence of formation by rifting from the Jurassic of Alexander Island, AntarcticaThe Middle Jurassic–Lower Cretaceous Fossil Bluff Group of Alexander Island, Antarctica represents the fill of a fore-arc basin unconformably overlying an accretionary complex. Like most fore-arc basins, this example had […]

Can marine mammals be used to monitor oceanographic conditions?
Read more of: Can marine mammals be used to monitor oceanographic conditions?The breeding performance of higher predators has often been used to monitor fluctuations in the abundance of important prey stocks in marine ecosystems. The development of electronic data-loggers in recent […]

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 […]

Bryozoan colonization of the marine isopod Glyptonotus antarcticus at Signy Island, Antarctica
Read more of: Bryozoan colonization of the marine isopod Glyptonotus antarcticus at Signy Island, AntarcticaSixty specimens of the giant marine isopod Glyptonotus antarcticus Eights, collected from Borge Bay, Signy Island, Antarctica were examined for epizoans. Ten species of cheilostomatid bryozoans were found on the […]
