Dense shelf water (DSW) overflows around Antarctica leads to the formation of antarctic bottom water, thereby driving the lower cell of global overturning circulation.
Understanding and quantifying the global methane (CH4) budget is important for assessing realistic pathways to mitigate climate change. CH4 is the second most important human-influenced greenhouse gas in terms of climate forcing after carbon dioxide (CO2)…

Recent studies have revealed the presence of a complex freshwater system underlying the Aurora Subglacial Basin (ASB), a region of East Antarctica that contains ?7 m of global sea level potential in ice mainly grounded below sea level. However…
Neutron monitors (NMs) are ground-based detectors that are widely used to detect secondary particles produced by the collisions of primary cosmic rays (CRs) and air molecules in the Earth's atmosphere. Bare neutron counters (BCs), operated without the lead producer and polyethylene reflector…
Introduction: This document updates the research bibliography of SC/66b/SAN01 presented in 2016. The Southern Ocean Sanctuary (SOS) was established by the Commission in 1994. The area covered by the SOS in combination with the complementary Indian Ocean Sanctuary (IOS) is shown in Figure 1.
Estimates of the distribution and density of Antarctic krill (Euphausia superba Dana, 1850) were derived from a large-scale survey conducted during the austral summer in the Southwest Atlantic sector of the Southern Ocean and across the Scotia Sea in 2018–19, the '2018–19 Area 48 Survey'.
The SCAR Krill Action Group (SKAG) provides a conduit for science to feed into the management of the Antarctic krill fishery, as well a more general forum to promote collaboration, help early career researchers, improve understanding of krill biology and ecology, and facilitate information exchange.
We have considered TOMS (2000–2004) and OMI (2005–2021) total ozone column (TOC) data sets for the second part of winter cold period (January–March). Variations in both total ozone and characteristics of the Fourier wave harmonics with zonal numbers 1–5 are analyzed.
Carbon monoxide (CO) is a naturally occurring atmospheric trace gas, a regulated pollutant, and one of the main components determining the oxidative capacity of the atmosphere. Evaluating climate…
Sea ice is a key habitat in the high latitude Southern Ocean and is predicted to change in its extent, thickness and duration in coming decades. The sea-ice cover is instrumental in mediating ocean…
The ecosystem approach to fisheries has been discussed since the 1980s. It aims to reduce risks from fisheries to whole, or components of, ecosystems, not just to target species. Precautionary approaches further aim to keep the risk of damage to a low level. Here…

Current interpretation of histological alteration in fish as an indicator of contaminant impact is subjective. Generally severity of alteration is poorly described, and does not allow direct comparison between studies. A histological health index (HHI) modified from Bernet et al (1999)…

Two sets of historical 3-ensemble simulations have been obtained with versions 1.0 and 1.3 of the Australian Community Climate and Earth System Simulator (ACCESS) to examine the effects of ozone change since 1960.
CryoSat-2 was launched in April 2010, as part of the European Space agency's (ESA) Earth Opportunity Programmes.
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.
