Around 176500 whales were killed in the sub-Antarctic waters off South Georgia (South Atlantic) between 1904 and 1965. In recent decades, whales have once again become summer visitors, with the southern right whale (SRW) the most commonly reported species until 2011. Here…
Molecular tools are increasingly applied for assessing and monitoring biodiversity and informing conservation action. While recent developments in genetic and genomic methods provide greater sensitivity in analysis and the capacity to address new questions…
It has been shown by Taguchi (2010) that QBO periods were longer and … amplitudes larger during periods of La Niña than during periods of El Niño during … the period 1953-2008. Garfinkel and Hartmann (2007)…
This study aims to assess the ability of climate models to reproduce observed stratosphere-troposphere coupling. Coupling between the stratosphere and troposphere is examined via the Southern and Northern Annular Modes (SAM and NAM). These modes…
The Southern Hemisphere mid-latitudes, particularly the area around south-eastern Australia and New Zealand, has been suggested as one of the regions where ozone recovery might first be detected…
Trends in surface atmospheric variables, namely temperature, wind speed and direction, cloud cover, and precipitation, display subtle patterns that are likely linked to climate change and the major modes of climate variability. In particular…
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…
Large-scale zonal asymmetries in the climatological spatial pattern of atmospheric variables such as geopotential height, temperature, and trace gas concentration are primarily dictated by the characteristics of quasi-stationary Rossby waves (QSWs).
