Geomagnetic storms represent a space weather hazard to power transmission networks due to the effects of induced geo-electric fields within the conducting surface of the Earth. These drive electric currents […]
Ground-based very low frequency transmitters emit signals that primarily propagate within the Earth–ionosphere waveguide, and some of their energy can propagate into the magnetosphere. Ionospheric observations from the DEMETER satellite […]
Future atmospheric warming could cause an abrupt increase in ocean temperature beneath the Filchner–Ronne Ice Shelf, Antarctica, from −2.2°C to more than 0°C in a few decades. In simulations, such […]
Synoptic weather systems play a crucial role in transporting moisture to Antarctica. Climate models project significant changes in these systems, including a wintertime intensification and a summertime poleward shift, with […]
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 […]
