1. Sunrise effects on VLF signals propagating over a long north-south path

   We present a detailed study of the times of amplitude minima observed on the 12-Mm path from NAA (24 kHz, 1 MW, Cutler, Maine) to Faraday, Antarctica, during the period […]

2. Electron acceleration at Jupiter: greater input from cyclotron-resonant interaction with whistler-mode chorus waves

   Jupiter has the most intense radiation belts of all the outer planets. It is not yet known how electrons can be accelerated to energies of 10 MeV or more. It […]

4. A re-examination of latitudinal limits of substorm-produced energetic electron precipitation

   The primary sources of energetic electron precipitation (EEP) which affect altitudes 30 keV) are expected to be from the radiation belts, and during substorms. EEP from the radiation belts should be […]

5. Global movement and homogenisation of biota: challenges to the environmental management of Antarctica

   Globally, many thousands of species have been redistributed beyond their natural dispersal ranges as a result of human activities. The introduction of non-native species can have severe consequences for indigenous […]

6. Setting the scene: human activities, environmental impacts and governance arrangements in Antarctica

   The scope and intensity of human activity in the Antarctic region has changed considerably over the past 100 years, resulting in significant modifications to the Antarctic environment and its ecosystems, […]

7. Comparison of modeled and observed effects of radiation belt electron precipitation on mesospheric hydroxyl and ozone

   Observations have shown that mesospheric hydroxyl (OH) is affected by energetic electron precipitation (EEP) at magnetic latitudes connected to the outer radiation belt. It is not clear, however, if the […]

8. Lower ionosphere monitoring by the South America VLF Network (SAVNET): C-region occurrence and atmospheric temperature variability

   Daily profiles of phase measurements as observed on fixed VLF-paths generally show a transient phase advance, followed by a phase delay, for about 90 minutes after sunrise hours. This is indicative […]

9. A potential feedback approach to ecosystem-based management: model predictive control of the Antarctic krill fishery

   CCAMLR aims to develop a feedback approach to aid ecosystem-based management (EBM) of Antarctic krill fisheries. It is important to assess whether a feedback approach is likely to achieve the […]

10. Precautionary spatial protection to facilitate the scientific study of habitats and communities under ice shelves in the context of recent, rapid, regional climate change

    Recent rapid climate change is now well documented in the Antarctic, particularly in the Antarctic Peninsula region. One of the most evident signs of climate change has been ice-shelf collapse; […]

11. Development of polymorphic microsatellite loci for three species of vent-endemic megafauna from deep-sea hydrothermal vents in the Scotia Sea, Southern Ocean

    Microsatellite loci have been developed for three undescribed species discovered at hydrothermal vents on the East Scotia Ridge (ESR) in the Southern Ocean: a yeti crab, Kiwa sp. (Kiwaidae), a […]

12. Multicolony tracking reveals potential threats to little auks wintering in the North Atlantic from marine pollution and shrinking sea ice cover

    Aim Extensive development of human activities in combination with ocean warming is rapidly modifying marine habitats in the Arctic and North Atlantic regions. To understand the potential impacts on marine […]
