Global climate models and reanalysis products have revealed large, persistent downwelling shortwave radiation biases over the Southern Ocean and coastal Antarctica, likely caused by the incapability of models to accurately simulate frequent low-level mixed-phase clouds in these regions.
Understanding past climate is essential to our knowledge of how our current climate system operates, and how it might respond to future change. Techniques to reconstruct climate history are challenging, and both accuracy and certainty are hampered by the quality of the datasets used.
The grey rockcod, Lepidonotothen squamifrons is an important prey species for seals, penguins and Patagonian toothfish (Dissostichus eleginoides) in the Southern Ocean. Across the Kerguelen Plateau, the species was fished to commercial extinction (ca. 152 000 tonnes between 1971 and 1978)…
While satellite altimeters have revolutionized ocean science, validation measurements in high wave environments are rare. Using geodetic Global Navigation Satellite System (GNSS) data collected from the Southern Ocean Flux Station (SOFS; ?47°S, 142°E) since 2019…
As a long-standing problem in climate models, large positive shortwave radiation biases exist at the surface over the Southern Ocean, impacting the accurate simulation of sea surface temperature, atmospheric circulation, and precipitation.
On January 15, 2022, an ongoing eruption at the Hunga-Tonga Hunga-Ha'apai volcano generated a large explosion which resulted in a globally observed tsunami and atmospheric pressure wave.
The Southern Ocean Research Partnership (IWC-SORP) is a multi-lateral, non-lethal scientific research programme established in 2009 to improve the coordinated and cooperative delivery of science to the IWC. There are 13 Partners: Argentina, Australia, Belgium, Brazil, Chile, France, Germany, Italy…
Patagonian toothfish (Dissostichus eleginoides) is a large bentho-pelagic fish species on the Kerguelen Plateau. Almost the entire Kerguelen Plateau is situated within the area managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)…
AIRBOX, a mobile air chemistry laboratory was deployed on the Australian ice-breaker, the RSV Aurora Australis for the 2018/2019 Antarctic resupply voyages. A comprehensive suite of atmospheric chemistry observations were made from ozone, mercury, CN, CCN, Nephelometer, MAAP…
Atmospheric electric field … measurements from the Concordia station on the Antarctic Plateau are … compared with those from Vostok (560 km away) for the period of overlap … (2009–11) and to Carnegie (1915–29) and extended Vostok (2006–11) measurements.
Reference IUGG-2058, Symposium M03 Weather and the Global Atmospheric Electric Circuit. Atmospheric electric field measurements from Concordia station on the Antarctic Plateau are compared with those from Vostok (560 km away) for the period of overlap (2009-2011) and to earlier Vostok (2006-2009)…
Chemistry–climate models are important tools for addressing interactions of composition and climate in the Earth system. In particular, they are used to assess the combined roles of greenhouse gases and ozone in Southern Hemisphere climate and weather.
