1. An unusual geometry of the ionospheric signature of the cusp: implications for magnetopause merging sites

   The 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 […]

2. 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 […]

3. Assessing the contamination of SuperDARN global convection maps by non-F-region backscatter

   Global 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 […]

4. Extremum statistics: a framework for data analysis

   Recent 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 […]

6. Cretaceous patterns of floristic change in the Antarctic Peninsula

   Cretaceous 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 […]

7. Silicic volcanism: an undervalued component of large igneous provinces and volcanic rifted margins

   Silicic 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 […]

8. Feeding increases MyoD and PCNA expression in myogenic progenitor cells of Notothenia coriiceps

   Oxygen 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 […]

10. Integrated environment-prey-predator interactions off South Georgia: implications for management of fisheries

    1. 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 […]

11. Estimating food consumption of marine predators: Antarctic fur seals and macaroni penguins

    1. 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 […]

12. Interactions of water, ice nucleators and desiccation in invertebrate cold survival

    Four case studies are used to examine the relationships of water, ice nucleators and desiccation in the cold survival of invertebrates and the viability of frozen plant material: the freeze […]
