Palaeomagnetic, 40Ar/39Ar, and stratigraphical correlation of Miocene–Pliocene basalts in the Brandy Bay area, James Ross Island, Antarctica
Read more of: Palaeomagnetic, 40Ar/39Ar, and stratigraphical correlation of Miocene–Pliocene basalts in the Brandy Bay area, James Ross Island, AntarcticaA revised stratigraphy of Cenozoic volcanic outcrops in the Brandy Bay area on James Ross Island is obtained by combining palaeomagnetic and stratigraphical anlysis with 40Ar/39Ar dating. The fieldwork was […]

Role of sea ice in forcing the winter climate of Antarctica in a global climate model
Read more of: Role of sea ice in forcing the winter climate of Antarctica in a global climate modelTwo different experiments have been conducted using the Hadley Centre’s atmosphere-only, global climate model to investigate the role of sea ice in forcing the Antarctic climate during the winter months.

Paleogene opening of Drake Passage
Read more of: Paleogene opening of Drake PassageThe timing of events leading to the earliest connection between the Pacific and Atlantic oceans at Drake Passage is controversial but important, because gateway opening probably had a profound effect […]

Modeling entrainment of sedimentary particles by wind and water: A generalized approach
Read more of: Modeling entrainment of sedimentary particles by wind and water: A generalized approachFor long-standing theoretical reasons, it is often asserted that the threshold shear stress for entrainment of sedimentary particles (τ*t = ρfu*2t, made dimensionless as A = ρfu*2t/((ρp − ρf)gd)) has […]

Solar wind-magnetosphere coupling leading to relativistic electron energization during high-speed streams
Read more of: Solar wind-magnetosphere coupling leading to relativistic electron energization during high-speed streamsEnhancements in relativistic electron fluxes in the outer radiation belt often occur following magnetic storms and have been suggested to result from resonant interactions with enhanced whistler-mode chorus emissions observed […]

Plasma astrophysics: Acceleration of killer electrons
Read more of: Plasma astrophysics: Acceleration of killer electronsRelativistic electrons in the outer Van Allen belt wreak havoc with satellites in geosynchronous orbit, but how they reach such high energies has been unclear. New data identify gyro-resonant wave-particle […]

Read more of: Macrofossil floras of the Latady Basin, Antarctic PeninsulaNew collections of plant material from the Merrick and Sweeney Mountains provide further evidence of Jurassic floral diversity in the Antarctic Peninsula. Eighteen taxa are recognised, including sphenophytes (Equisetum), ferns […]

Ferns from the Cretaceous of Alexander Island, Antarctica: Implications for Cretaceous phytogeography of the Southern Hemisphere
Read more of: Ferns from the Cretaceous of Alexander Island, Antarctica: Implications for Cretaceous phytogeography of the Southern HemisphereSix new records of ferns from the late Albian flora of Alexander Island, Antarctic Peninsula, provide further evidence for a widespread Cretaceous Austral flora. Phyllopteroides antarctica sp. nov. is the […]

A new Eocene Araucaria from Seymour Island, Antarctica: evidence from growth form and bark morphology
Read more of: A new Eocene Araucaria from Seymour Island, Antarctica: evidence from growth form and bark morphologyAraucarian conifers are an important component of Cretaceous through Paleogene floras in the Antarctic Pensinsula. A well-preserved Eocene petrified trunk from Seymour Island, Antarctica reveals the growth form and bark […]

Taxonomic turnover and abundance in Cretaceous to Tertiary wood floras of Antarctica: implications for changes in forest ecology
Read more of: Taxonomic turnover and abundance in Cretaceous to Tertiary wood floras of Antarctica: implications for changes in forest ecologyBased on the temporal distribution, abundance, and taxonomic composition of wood floras, four phases of vegetation development are recognized through the Cretaceous to Early Tertiary of the Antarctic Peninsula: (1) […]
