We explore the utility of estimating the density of calls of baleen whales for better understanding acoustic trends over time. We consider as a case study stereotyped 'song' calls of Antarctic blue whales (Balaenoptera musculus intermedia)…

Components such as organic carbon (Corg), carbonate, opal or barite are valuable paleoceanographic proxies, enabling the reconstruction of past changes in carbon cycling under various climate regimes, particularly when 230Th-normalization is used to reconstruct particulate vertical rain rates.

Primary productivity by phytoplankton in the Southern Ocean can be limited by low iron concentrations. Iron limitation in the surface ocean around Antarctica may be alleviated by particle dissolution of dust from exposed rock, glacial flour, resuspended marine sediment, and sea ice. Ligands…

Baleen whales are extreme capital breeders, capable of fasting for more than half a year while migrating thousands of kilometres and nursing rapidly growing offspring that quadruple in body size over the same period. To understand this energetic conundrum…

Antarctica is a well-established space analogue environment where expeditioners face challenges similar to those experienced in human spaceflight.

Surveillance monitoring is important for detecting variations in species populations in response to natural and anthropogenic environmental changes. For seabirds this typically involves species-specific monitoring at breeding colonies.

Data collection facilitated by remotely piloted aircraft (RPA) has proven to be revolutionary in many disciplines including for research in extreme environments. Here we assess current use and utility of small multirotor remotely piloted aircraft (RPAs)…

The future response of the Antarctic Slope Current (ASC) to projected transient changes in winds, radiative forcing, and meltwater input is examined in a high-resolution ocean-sea ice model. Meltwater changes are found to dominate the almost -circumpolar strengthening of the ASC.

Interleaving layers are commonly observed in the subsurface ocean near thermohaline fronts. They imply a lateral exchange of water mass properties and have been shown to influence both lateral and vertical mixing rates. We examine a set of in situ observations…

Incidental mortality in fisheries is a major driver of population declines for albatrosses and petrels globally. However, accurate identification of species can be difficult due to the poor condition of bycaught birds and/or visual similarities between closely related species.

Global chemistry–climate models (CCMs) play an important role in assessing the climate and air pollution implications of aerosols and chemically reactive gases.

Antarctic krill (Euphausia superba Dana) is a key species of the Southern Ocean ecosystem, immensely abundant and targeted by the krill fishery. For their sustainable management, krill distribution and biomass estimates are required, typically achieved through acoustic-trawl surveys.

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.

The development of the Antarctic ozone hole in late winter and spring (September–November) is the most … noticeable phenomenon in the polar stratosphere. It has appeared every season since the early 1980s within the … stratospheric polar vortex…

Satellite tagging provides vital information about the ecology of whales, not currently obtainable in any other way, but it can elicit short- and long-term impacts on individuals.

Allocation of energy is as important as energy uptake for maintaining healthy life cycles and sustainable populations of krill. Environmental factors such as temperature and food availability play important roles in the physiological performance of krill.

Basal sliding in Antarctic glaciers is often modeled using a friction law that relates basal shear stresses to the effective pressure. As few ice sheet models are dynamically coupled to subglacial hydrology models…

The largest regional drivers of current surface elevation increases in the Antarctic Ice Sheet are associated with ice flow reconfiguration in previously active ice streams, highlighting the important role of ice dynamics in mass balance calculations. Here…

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)…

All aspects of biodiversity research, from taxonomy to conservation, rely on data associated with species names. Effective integration of names across multiple fields is paramount and depends on the coordination and organization of taxonomic data.

Antarctic terrestrial biodiversity faces multiple threats, from invasive species to climate change. Yet no large-scale assessments of threat management strategies exist. Applying a structured participatory approach…

The Antarctic marine environment, although rich in life, is predicted to experience rapid and significant effects from climate change. Despite a revolution in the approaches used to document biodiversity…

Bryophytes are the group of land plants with the lowest photosynthetic rates, which was considered to be a consequence of their higher anatomical CO2 diffusional limitation compared with tracheophytes. However…

Antarctic biodiversity faces an unknown future with a changing climate. Most terrestrial biota is restricted to limited patches of ice-free land in a sea of ice, where they are adapted to the continent's extreme cold and wind and exploit microhabitats of suitable conditions.

The Antarctic climate-diversity-invasion hypothesis (ACDI) predicts that in Antarctic soil systems, climate change should lead to increases in the abundance and diversity of indigenous assemblages. Where biological invasions have occurred, however…
