A holistic review is given of the Southern Ocean dynamic system, in the context of the crucial role it plays in the global climate and the profound changes it is experiencing. The review focuses on connections between different components of the Southern Ocean dynamic system…
Levoglucosan (LEV) and two of its isomers, mannosan (MAN) and galactosan (GAL), are commonly used as biomass burning tracers, however 1,6-anhydro-?-D-glucofuranose (AGF), another isomer derived from biomass burning, is rarely identified or quantified in existing literature.
Signatories to the Antarctic Treaty System's Environmental Protocol are committed to preventing incursions of non-native species into Antarctica, but systematic surveillance is rare. Environmental DNA (eDNA)…
Antarctic conservation science is crucial for enhancing Antarctic policy and understanding alterations to terrestrial Antarctic biodiversity. Antarctic conservation will have limited long-term impacts in the absence of large-scale biodiversity data, but if such data were available…
This study presents the first record of trifluoroacetic acid (TFA) in Antarctic ice cores, offering valuable data on TFA and its precursors' long-range atmospheric transport and deposition in remote polar regions. TFA is an ultra-short chain perfluoroalkyl acid (PFAA)…
Levoglucosan (LEV) and two of its isomers, mannosan (MAN) and galactosan (GAL), are commonly used as biomass burning tracers, however 1,6-anhydro-?-D-glucofuranose (AGF), another isomer derived from biomass burning, is rarely identified or quantified in existing literature.
Metals are important nutrients to marine life but may cause toxicity at elevated concentrations. There is uncertainty about how sediment metal concentrations influence benthic biodiversity, in part because metal bioavailability depends on sediment properties.
The presence of unique biological archives (e.g., springtails, Arthropoda: Collembola) in Antarctic ice-free regions provides powerful evidence for testing assumptions about when and how the current ice sheet reached its present-day configuration. Springtails, where present, may suggest long-term…
Antarctica, Earth's least understood and most remote continent, is threatened by human disturbances and climate-related changes, underscoring the imperative for biodiversity inventories to inform conservation. Antarctic ecosystems support unique species and genetic diversity…
The terrestrial amphipod Puhuruhuru patersoni (Amphipoda: Talitridae) was discovered on sub-Antarctic Macquarie Island in 1992. The species is only known to naturally occur on New Zealand's South Island and some associated offshore islands.
The majority of islands surrounding the Antarctic continent are poorly characterized in terms of microbial macroecology due to their remote locations, geographical isolation and access difficulties. The 2016/2017 Antarctic Circumnavigation Expedition (ACE)…

Our understanding of cross-disciplinary connections for Antarctica's role in the Earth system remains incomplete, especially around its coastal margins. The focus here is on sea-ice, oceanic, and atmospheric drivers in the joint Ross Sea-far East Antarctic Region (RSfEAR)…
