We have obtained horizontal phase velocity distributions of the gravity waves around 90 km from four Antarctic airglow imagers, which belong to an international airglow imager/instrument network known as ANGWIN […]
Penguins are an important indicator of marine ecosystem health and a major contributor of nutrients to terrestrial ecosystems in Antarctica. Their stomach microbiota is influenced by both the prey consumed […]
Daily radiosonde observations between 2003 and 2013 from Halley research station, Antarctica (75°S, 26°W) are used to determine climatologies of gravity wave properties in the lower stratosphere (between 15 km […]
Tritiated water dilution was used to measure changes in the proximate body composition of adult female southern elephant seals at the end of lactation and at the beginning and end […]
Growth of upper canine teeth of male Antarctic fur seals (Arctocephalus gazella) which died of natural causes at Bird Island, South Georgia, was quantified from measurements of annual layers in […]
A census of the breeding population of Antarctic fur seals (Arctocephalus gazella) at South Georgia was carried out during the 1990/91 breeding season. Using counts of adult females ashore at […]
Sr-isotope data from the Rubh’an Eireannaich sill, one of a suite of composite (mafic-silicic) minor intrusions associated with the 59 Ma Skye Intrusive Centre, NW Scotland, indicate that both crystal-liquid […]
