In contrast to a strong decrease in Arctic sea ice extent, overall Antarctic sea ice extent has modestly increased since 1979. Several hypotheses have been proposed for the net Antarctic sea ice expansion, including atmosphere/ocean circulation and temperature changes…
A proof-of-concept study was conducted to explore the viability of automated acoustic detection of upcall vocalisations produced by southern right whales (Eubalaena australis) on their high-latitude Antarctic feeding grounds. The automated acoustic detector used was that of Shiu et al (2020)…
While definitive winter measurements for Dome C must await until 2004, on the basis of existing data the Antarctic … Dome sites promise the best conditions on the Earth for many astronomical observations. Because atmospheric … turbulence is largely confined to a ~ 100 m ground layer…
The 2007 Antarctic ozone hole is reviewed from a variety of … perspectives, making use of various Australian data and analyses. The 2007 ozone hole was relatively modest, particularly … in comparison to that of 2006…
The association between Southern Hemisphere cyclones and anticyclones and the El Niño–Southern … Oscillation (ENSO), southern annular mode (SAM), Antarctic sea ice extent (SIE), and rainfall in Perth … and Melbourne is explored. Those cities are, respectively…
The role played by Southern Hemisphere sea ice in the global climate system is explored using an earth … system climate model of intermediate complexity.
The role played by Southern Hemisphere sea-ice in global climate is explored using an … Earth system climate model of intermediate complexity.
Most of what has been said about modern Antarctic climate change is based on studies of … meteorological observations that extend back the 1950s. Most attention to Antarctic ice core … records is focused on the timescale of glacial-interglacial cycles.
The so-called ionosonde drift technique of determining ionospheric velocities from angle-of-arrival and Doppler shift measurements is now well established. In the standard digital ionosonde technique, commonly called the drift mode…
Seasonal and interannual variations of the mixed layer properties in the Antarctic Zone (AZ) south of Tasmania are … described using7 WOCE/SR3 CTD sections and 8 years of summertime SURVOSTRAL XBT and thermosalinograph … measurements between Tasmania and Antarctica. The AZ…
