An unusual geometry of the ionospheric signature of the cusp: implications for magnetopause merging sites
Read more of: An unusual geometry of the ionospheric signature of the cusp: implications for magnetopause merging sitesThe HF radar Doppler spectral width boundary (SWB) in the cusp represents a very good proxy for the equatorward edge of cusp ion precipitation in the dayside ionosphere. For intervals […]

Ionospheric signatures of split reconnection X-lines during conditions of IMF Bz < 0 and |By| ∼ |Bz|: Evidence for the antiparallel merging hypothesis
Read more of: Ionospheric signatures of split reconnection X-lines during conditions of IMF Bz < 0 and |By| ∼ |Bz|: Evidence for the antiparallel merging hypothesis[1] We present measurements of the convection electric field in the dayside ionosphere during extended intervals when the interplanetary magnetic field (IMF) has a negative Bz component and a significant […]

Assessing the contamination of SuperDARN global convection maps by non-F-region backscatter
Read more of: Assessing the contamination of SuperDARN global convection maps by non-F-region backscatterGlobal convection mapping using line-of-sight Doppler velocity data from the Super Dual Auroral Radar Network (SuperDARN) is now an accepted method of imaging high-latitude ionospheric convection. This mapping process requires […]

Extremum statistics: a framework for data analysis
Read more of: Extremum statistics: a framework for data analysisRecent work has suggested that in highly correlated systems, such as sandpiles, turbulent fluids, ignited trees in forest fires and magnetization in a ferromagnet close to a critical point, the […]

Cretaceous patterns of floristic change in the Antarctic Peninsula
Read more of: Cretaceous patterns of floristic change in the Antarctic PeninsulaCretaceous radiation of angiosperms from low to high palaeolatitudes, coupled with the break-up of Gondwana, played a major role in establishing and maintaining biogeographic patterns across the southern hemisphere. Uncertainties […]

Silicic volcanism: an undervalued component of large igneous provinces and volcanic rifted margins
Read more of: Silicic volcanism: an undervalued component of large igneous provinces and volcanic rifted marginsSilicic volcanic rocks are associated with most, if not all, continental flood basalt provinces and volcanic rifted margins, where they can form substantial parts of the eruptive stratigraphy and have […]

Feeding increases MyoD and PCNA expression in myogenic progenitor cells of Notothenia coriiceps
Read more of: Feeding increases MyoD and PCNA expression in myogenic progenitor cells of Notothenia coriicepsOxygen consumption and ammonia excretion of the Antarctic fish Notothenia corikeps (18.4 cm L-F) increased respectively two and fourfold above fasting levels 24 h after feeding with a single meal […]

Integrated environment-prey-predator interactions off South Georgia: implications for management of fisheries
Read more of: Integrated environment-prey-predator interactions off South Georgia: implications for management of fisheries1. The oceanography of the South Georgia region is principally that of the Southern Ocean rather than the South Atlantic. A combination of factors, including advection, local bathymetry and high […]

Estimating food consumption of marine predators: Antarctic fur seals and macaroni penguins
Read more of: Estimating food consumption of marine predators: Antarctic fur seals and macaroni penguins1. Estimating food consumption is central to defining the ecological role of marine predators. This study developed an algorithm for synthesizing information about physiology, metabolism, growth, diet, life history and […]
