Demonstrating the use of a class of min-max smoothers for D-region event detection in narrowband VLF phase
Read more of: Demonstrating the use of a class of min-max smoothers for D-region event detection in narrowband VLF phaseThis paper describes the use of a class of non‐linear smoothers for the identification of interesting phenomena in narrowband very low frequency (VLF) transmission phase caused by perturbation events in […]

Decadal-scale progression of Dansgaard-Oeschger warming events
Read more of: Decadal-scale progression of Dansgaard-Oeschger warming eventsDuring the last glacial period, proxy records throughout the Northern Hemisphere document a succession of rapid millennial-scale warming events, called Dansgaard–Oeschger (DO) events. A range of different mechanisms has been […]

The effect of ozone shadowing on the D region ionosphere during sunrise
Read more of: The effect of ozone shadowing on the D region ionosphere during sunriseDiurnal very low frequency (VLF) sub‐ionospheric radiowave phase measurements show a night‐to‐day transition pattern. During this sunrise transition a phase perturbation, which consist of a phase overshoot followed by a […]

Happy feet in a hostile world? The future of penguins depends on proactive management of current and expected threats
Read more of: Happy feet in a hostile world? The future of penguins depends on proactive management of current and expected threatsPenguins face a wide range of threats. Most observed population changes have been negative and have happened over the last 60 years. Today, populations of 11 of the 18 penguin […]

Flow of the Brunt Ice Shelf, Antarctica, derived from Landsat images, 1974–85
Read more of: Flow of the Brunt Ice Shelf, Antarctica, derived from Landsat images, 1974–85Satellite images recorded in 1973, 1974, and 1985 of the Brunt Ice Shelf are compared. There are sufficient identifiable features moving with the ice shelf to show flow patterns over […]

Factors affecting the breeding performance of Antarctic blue-eyed shags Phalacrocorax atriceps
Read more of: Factors affecting the breeding performance of Antarctic blue-eyed shags Phalacrocorax atricepsThe breeding performance of Blue-eyed shags of known age (up to 12 yr old) was studied on Signy Island, South Orkney Islands for three seasons. Mate change between seasons was […]

The relationship between dominance behaviour, bill size and age group in Greater Sheathbills Chionis alba
Read more of: The relationship between dominance behaviour, bill size and age group in Greater Sheathbills Chionis albaA dominance hierarchy developed within a wintering flock of Greater Sheathbills which fed regularly at a concentrated artificial food source. Each bir’s dominance position was determined from the proportion of […]
