The ACCESS 1-0 and ACCESS 1.3 now have a set of 3 historical ensemble members which include the late 20th Century and early 21st Century (2020) simulations. Recently we have just completed a new set of experiments designed to investigate the impact of the perturbation in ozone since 1960.
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…
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).
A decade of radiosonde observations of wind and temperature in the troposphere and lower stratosphere have made it possible to compile a climatology of low-frequency gravity waves above Davis, Antarctica (69S, 78E). Wave characteristics, extracted using wavelet analysis [Zink and Vincent, 2001]…

The upper troposphere and lower stratosphere (UTLS) is a highly coupled region of the atmosphere where radiation, dynamics, clouds and chemical processes interact on a wide variety of spatial and temporal scales. We use a suite of instruments at Davis, Antarctica (69S, 78E)…

This study aimed to describe the migratory distribution and behaviour of pygmy blue whales … that feed in the Perth Canyon region off the coast of Western Australia.
The joint TOT-Cal / CryoVExANT2011 project contributes to the validation of the CryoSat-2 altimetry mission through investigations of a key portion of the East Antarctic ice sheet near Australia’s Casey Station. Spanning parts of Law Dome and the Totten Glacier…
The TotCal / CryoVExANT2011 project is an Australian and German collaboration that contributes to the validation of the CryoSat-2 radar altimetry mission through investigations of a key portion of East Antarctica near the Australian Casey Station.
Tropospheric ozone is a greenhouse gas, ranked third in anthropogenic radiative forcing after CO2 and CH4. Ozone in the troposphere makes up an important fraction of the atmospheric shield against ultraviolet … radiation particularly when stratospheric ozone depletion events occur.
The 2012 ozone hole was one of the smallest since the late 1980fs due to a warmer than normal mid]lower … stratosphere over the Antarctic region this year. The development and recovery of the 2012 ozone hole will … be shown via a set of metrics based on the Ozone Monitoring Instrument (OMI)…

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…
Measurements of mesosphere and lower thermosphere (MLT) winds obtained using a 2 MHz … radar at Davis (68.6S, 78.0E) from 1993 to the present have allowed the compilation of a … climatology of planetary wave activity and horizontal momentum fluxes.
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.
Abstract: Two sediment cores collected from beneath the Amery Ice Shelf, East Antarctica describe the … physical sedimentation patterns beneath an existing major embayed ice shelf. Core AM01b was collected … from a site of basal freezing, contrasting with core AM02…
This paper presents extensive {bias determination} analyses of ozone observations from the Atmospheric Chemistry Experiment (ACE) satellite instruments: the ACE Fourier Transform Spectrometer (ACE-FTS)…
