Echinoderm faunas from the lower Cretaceous (Aptian–Albian) of Alexander Island, Antarctica
Read more of: Echinoderm faunas from the lower Cretaceous (Aptian–Albian) of Alexander Island, AntarcticaStrata assigned to the Fossil Bluff Group on Alexander Island, Antarctica, contain Aptian to Albian highlatitude echinoderm faunas that lived at palaeolatitudes greater than 60 degrees south. The Pluto Glacier […]

Basal crevasses in Larsen C Ice Shelf and implications for their global abundance
Read more of: Basal crevasses in Larsen C Ice Shelf and implications for their global abundanceBasal crevasses extend upwards from the base of ice bodies and can penetrate more than halfway through the ice column under conditions found commonly on ice shelves. As a result, […]

Evidence for a two-phase Palmer Land event from crosscutting structural relationships and emplacement timing of the Lassiter Coast Intrusive Suite, Antarctic Peninsula: Implications for mid-Cretaceous Southern Ocean plate configuration
Read more of: Evidence for a two-phase Palmer Land event from crosscutting structural relationships and emplacement timing of the Lassiter Coast Intrusive Suite, Antarctic Peninsula: Implications for mid-Cretaceous Southern Ocean plate configurationNew analysis of the relationships between geological structural data and radiometric ages for the Lassiter Coast Intrusive Suite indicate that the collisional mid-Cretaceous Palmer Land Event orogeny in the Antarctic […]

Physiological plasticity, long term resistance or acclimation to temperature, in the Antarctic bivalve, Laternula elliptica
Read more of: Physiological plasticity, long term resistance or acclimation to temperature, in the Antarctic bivalve, Laternula ellipticaTo further investigate the previously reported limited acclimation capacities of Antarctic marine stenotherms, the Antarctic mud clam, Laternula elliptica (King and Broderip, 1830–1831), was incubated at 3.0 °C for 89 […]

Extreme natal philopatry in female Antarctic fur seals (Arctocephalus gazella)
Read more of: Extreme natal philopatry in female Antarctic fur seals (Arctocephalus gazella)Natal philopatry is an important component of mammalian behaviour but is difficult to study in natural vertebrate populations due to the requirement for long-term individual-based spatial observations. Consequently, we quantified […]

The contribution of wave-particle interactions to electron loss and acceleration in the Earth’s radiation belts during geomagnetic storms
Read more of: The contribution of wave-particle interactions to electron loss and acceleration in the Earth’s radiation belts during geomagnetic stormsThe Earth’s radiation belts are a hazardous environment that pose a risk to astronauts and spacecraft on orbit. Having been discovered in 1958, there is renewed interest on the part […]

Efficient diffuse auroral electron scattering by electrostatic electron cyclotron harmonic waves in the outer magnetosphere: A detailed case study
Read more of: Efficient diffuse auroral electron scattering by electrostatic electron cyclotron harmonic waves in the outer magnetosphere: A detailed case studyThis paper is a companion to a paper by Liang et al. (2011) which reports a causal connection between the intensification of electrostatic ECH waves and the postmidnight diffuse auroral […]
