This 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 […]
During 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 […]
Diurnal 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 […]
Penguins 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 […]
Satellite 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 […]
The 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 […]
A 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 […]
