Global chemistry–climate models (CCMs) play an important role in assessing the climate and air pollution implications of aerosols and chemically reactive gases.
Understanding basal processes across ice-sheet grounding lines is crucial in accurately modeling ice-sheet dynamics and estimating global sea-level rise. The grounding line, which demarcates the specific boundary between a grounded ice sheet and a floating ice shelf…
Monitoring variability in predator diets can highlight key parameters for understanding and managing marine ecosystems. Penguin diets provide useful indicators of ecosystem variability and several species, including Adélie penguins (Pygoscelis adeliae)…
We present a synthesis of marine soft sediment macrofaunal communities from the Vestfold Hills, East Antarctica, spanning historical data (1978–1982) and recent surveys from 47 locations (2010–2021). We examined relationships between environmental conditions…
Invasive species are a significant threat to marine ecosystems, contributing to biodiversity loss and ecosystem … changes. Biofouling, the accumulation of aquatic organisms on vessel hulls, is one of the main pathways for … invasive species worldwide…
Airborne environmental DNA (airborne eDNA) analysis leverages the globally ubiquitous medium of air to deliver broad species distribution data and support ecosystem monitoring across diverse environments. As this emerging technology matures…
New edition of the leading resource on the Arctic and Southern Oceans with contributions from the world's experts on sea ice. Sea Ice delivers insights into the very latest understanding of sea ice dynamics, how we measure (and model) its extent, the ecosystems that depend on sea ice…
A technique has recently been developed for tracking short-term spectral variations in Galactic cosmic rays (GCRs) using data from a single neutron monitor (NM)…
Snow on sea ice plays a critical role in the global climate system, affecting the growth and decay of the ice, polar ecosystems, human activities, and the retrieval of sea ice characteristics from remote sensing data.
US and Australian researchers are collaborating to study how extreme, isolated environments in Antarctica affect health, using this research to develop and test new mental and physical health technologies for astronauts on long-duration space missions.
The retreat of Antarctic ice shelves due to calving and the subsequent reduction in buttressing of the Antarctic Ice Sheet are of major concern for future sea-level rise. Sudden…
This online article is part of Our Wondrous Planet exhibition from Museums Victoria. It is part of behind-the-scenes stories about some of the creatures and ecosystems that make up our wondrous planet.
The Australian Antarctic Program (AAP) serves as a unique Earth-based analog for space travel, using its extreme, isolated environments to conduct research that directly supports long-duration human spaceflight. Studies focus on the long-term effects of confinement and isolation on human health…
Australian Antarctic Space Analogue: A research project using the Antarctic environment to study the effects of isolation, confinement, and extreme conditions on human physiology and psychology, relevant to long-duration spaceflight. Medical Model:
Antarctic sea ice plays many crucial roles in the physical environments and ecosystems of Antarctica and the Southern Ocean. In this study, we synthesize the physical, biogeochemical, ecosystem, and societal impacts of summers with extreme low Antarctic sea-ice coverage.
The mesosphere and lower thermosphere (MLT) comprise a highly variable region that forms the transition region between the middle and upper atmosphere.
One of the largest sectors of the Southern Ocean is the Indian Sector, which plays an important role in regulating the Earth's climate and supports a diverse ecosystem. To understand how climate change impacts the environment in this sector…
Human-caused climate change worsens with every increment of additional warming, although some impacts can develop abruptly. The potential for abrupt changes is far less understood in the Antarctic compared with the Arctic, but evidence is emerging for rapid…
This paper explores the research, making, and performance of Sastrugi: Sounds of Antarctic Sea Ice. Combining the techniques of sonification, field recording, and musique concrète, Sastrugi orchestrates multi-sensory world building for the audience where immersive soundscapes…
Gravity waves provide a key mechanism for the vertical transport of energy and momentum from the active near-surface weather to the upper reaches of the neutral and ionised atmosphere. Generation mechanisms vary between storms, fronts…
Vincennes Bay is a region of East Antarctica vulnerable to sub-ice shelf basal melting from warm ocean water intrusions. The sub-ice shelf bathymetry in this region is largely unknown, despite its importance for ocean dynamics within ice shelf cavities and associated sub-ice shelf basal melting.
