East Antarctica experienced two recent heatwaves with no historical precedent, in March 2022 in Wilkes Land (WL), and July–August 2024 in Dronning Maud Land (DML). In this study, a large […]
Reconstructing environmental changes near ice margins that have deglaciated since the Last Glacial Maximum (LGM) is essential for understanding future changes of the Antarctic Ice Sheet. Here, we conducted a […]
Ice core records of preindustrial methane indicate variability of ± 30 ppb ( ± 5%) on multidecadal-to-centennial timescales. Previous work has attributed these excursions to low-frequency or episodic changes in […]
Gregarines are symbionts of the gut or other body cavities associated with numerous insect species. Knowledge about natural gregarine infection levels and across metamorphosis in holometabolous hosts is sparse. Individuals […]
Key points Seafloor hotspots and 7,252 new benthic invertebrates have been described since the publication of the second World Ocean Assessment, and there has been a five-fold increase in critically […]
Mercury (Hg) can negatively affect marine biota through uptake from prey and from the surrounding environment. Cephalopods constitute a major prey group in Southern Ocean ecosystems, yet little is known […]
Recent decades have seen record-high temperatures on the Antarctic Peninsula (AP) due to combined atmospheric rivers (ARs) and föhn warming. While ARs frequently enhance föhn, not all events cause surface […]
As heatwaves increase in both frequency and intensity globally, the need to develop tools to predict the human impact and develop a more comprehensive understanding of the impact mechanism at […]
Recent sub-ice topography investigations have imaged—with greatly improved detail—a set of low-elevation V-shaped basins hidden beneath a very large sector of the East Antarctic Ice Sheet. Here we jointly interpret […]
The marine biological carbon cycle plays a crucial role in the sinking and sequestration of atmospheric carbon and in regulating the global climate. Most existing research on biological carbon sequestration […]
Assessing extinction risk is important for protecting species, as it is the starting point for conservation efforts. However, in Antarctica, none of the c. 116 species of bryophytes (the main […]
