Meteoroids of sub-milligram sizes burn up high in the Earth's atmosphere and cause streaks of plasma trails detectable by meteor radars. The altitude at which these trails, or meteors…
The relationships between flying Antarctic seabirds and their at-sea environments remain poorly understood, particularly outside of the breeding season. Improving our knowledge of how these marine predators use their habitat is a critical step towards conservation of these species.
This study presents evidence of diel patterns in fin whale (Balaenoptera physalus) 20 Hz acoustic presence in Eastern Antarctic waters. Passive acoustic recordings were collected at four sites in Eastern Antarctica from 2013 to 2019.
The Antarctic ozone hole of 2011 is reviewed from a variety of perspectives, making … use of various data and analyses. The ozone hole of 2011 was relatively large … in terms of maximum area, minimum ozone level and total ozone deficit…
The cause of seasonal trends in the zonal asymmetry of the total ozone column (TOC) at high southern latitudes are examined. Using ERA-Interim assimilated meteorological data, we examine characteristics of extra-tropical Rossby waves…

resulted in devastating bushfires igniting in south-eastern Australia. As a result, a significant amount of smoke aerosols was injected into the upper troposphere-lower stratosphere (UTLS) region. Its properties, in particular H2O enhancement inside the smoke plume…
The total ozone column (TOC) in the 'collar' region outside the Antarctic Ozone Hole exhibits a pronounced wave-1 zonal pattern in austral spring. During the period 1979-2005, the zonal minimum of the pattern exhibited a general eastward shift of approximately 45 degrees of longitude…
As revealed by the CALIPSO orbiting lidar, the intense firestorms that occurred … in southern Australia during February 2009 injected a significant plume of … smoke particles into the lower stratosphere. Over the following weeks…
The temporal evolution of the subauroral polarization stream (SAPS) is investigated … using the Doppler velocity observations by the Unwin HF radar in conjunction with … the simultaneously observed auroral luminosity and plasma convection reversal regions. The event under study of 14 December 2004…
