Bdelloid rotifers are an important component of the biodiversity of ice-free regions of Antarctica. Despite this, knowledge of how to establish and maintain cultures, and optimal conditions for growth, is limited.
From 1979 to 2016, total Antarctic sea ice extent experienced a positive trend with record winter maxima in 2012 and 2014. Record summer minima followed within the period 2017-2024, raising the possibility that the Antarctic sea ice system might be changing state.
The advent of under-ice profiling float and biologging techniques has enabled year-round observation of the Southern Ocean and its Antarctic margin. These under-ice data are often overlooked in widely used oceanographic datasets…
Elasmobranchs (sharks, skates and rays) are among the least productive fish species, which make their populations vulnerable to increased mortality. Although skates exhibit elevated vulnerability to fishing, they are commonly caught as incidental bycatch in demersal fisheries.
Cosmic rays are charged particles whose flux observed at Earth shows temporal variations related to space weather phenomena and may be an important tool to study them. The cosmic ray intensity recorded with ground-based detectors also shows temporal variations arising from atmospheric variations.
Major mid-winter stratospheric sudden warmings (SSWs) are the largest instance of wintertime variability in the Arctic stratosphere. Because SSWs are able to cause significant surface weather anomalies on intra-seasonal timescales…
We present an overview of … state-of-the-art chemistry–climate and chemistry transport models that … are … used within phase 1 of the Chemistry–Climate Model Initiative (CCMI-1).
Background: Free ocean CO2 enrichment experiments (FOCE) were developed to address the need for information on community level response to ocean acidification in natural habitats. The antFOCE project was the first polar FOCE system and was run at Casey Station, East Antarctica…
Better characterisation of aerosol processes in pristine, natural environments, such as Antarctica, have recently been shown to lead to the largest reduction in uncertainties in our understanding of radiative forcing.
