On average, about 45 per cent of global annual anthropogenic carbon dioxide (CO2) emissions remain in the atmosphere, while the remainder are taken up by carbon reservoirs on land and […]
It has long been held that Eudyptes penguins will only ever develop a maximum of two mature yolky follicles to match their invariant two-egg clutch, an idea inferred largely from […]
It has long been known that birds change their behaviour, reproductive performance and survival as they mature, including in the first few years after recruitment into the breeding population. However, […]
Aim: To present a synthesis of past biogeographic analyses and a new approach based on spatially explicit biodiversity information for the Antarctic region to identify biologically distinct areas in need […]
We have collected ice penetrating polarimetric radar data on Brunt, George VI and Ronne ice shelves using a vector network analyser as a continuous wave (CW) step-frequency radar. Being a […]
The polarisation behaviour of radar waves transmitted through Brunt Ice Shelf at a site near Halley has been investigated using a step-frequency radar with a centre frequency of 300 MHz […]
This paper describes the novel technique of using a phase-sensitive radio-echo system to determine the basal melt rate along a short profile near Halley Station on the Brunt Ice Shelf. […]
