Missing gravity wave drag near 60 degrees south has been proposed as the cause of the common cold bias in modelled southern polar stratospheric temperatures [McLandress et al. 2012]. Potential gravity wave momentum sources around those latitudes, such as jets…
Current interpretation of histological alteration in fish as an indicator of contaminant impact is subjective. Generally severity of alteration is poorly described, and does not allow direct comparison between studies. A histological health index (HHI) modified from Bernet et al (1999)…

We report the first observations of simultaneous high?]latitude interhemispheric F region … neutral wind fields by combining the 630 nm optical measurements from two scanning … Doppler imagers (SDIs) and three Fabry?]Perot interferometers (FPIs) for a period … exceeding 5 h.
Although huddling was shown to be the key by which emperor penguins (Aptenodytes forsteri) save energy and sustain their breeding fast … during the Antarctic winter, the intricacies of this social behavior have been poorly studied.
The continent of Antarctica has experienced some of the largest rates of both surface warming and cooling found anywhere on the planet. Unlike in the Arctic, where sea ice has been declining…
A major source of energy during lactation in mammals is provided … through the mobilization of blubber fatty acids (FAs).
Protection of the wilderness and aesthetic values of Antarctica is mandated by the Protocol on Environmental Protection to the Antarctic Treaty, the “Madrid Protocol,” which came into force in 1998. Despite the passage of over 13 years…
Callipallenid sea spiders are commonly found in southern Australian waters. The genera Pseudopallene and Stylopallene are frequent epibionts of arborescent bryozoan colonies of Orthoscuticella spp. and Amathia spp. Based on external morphology, colouration patterns…
Shallow-water benthic communities throughout coastal Antarctica share many species and are governed by similar physico-oceanographic processes.
For many species trophic interactions are difficult to study because of their cryptic habits and/or the unfavourable characteristics of samples for traditional diet techniques. DNA-based diet techniques are sensitive…
We report the first observations of simultaneous high-latitude inter-hemispheric F-region neutral wind fields by combining the 630 nm optical measurements from two scanning Doppler imagers and three Fabry-Perot interferometers for a period exceeding 5 hours on 3 October 2008.
The mid- to high-latitudes of the Southern Hemisphere are dominated by the westerly winds. These are important because changes in their strength determine precipitation and temperature regimes. However, little is known about their past strength, or spatial and temporal variability.
