The Arctic Ocean is characterized by substantial seasonal and inter-annual variability, of which the sources and impacts are not yet fully understood. Here, we analyze how much of the variability […]
The THINICE field campaign, based from Svalbard in August 2022, provided unique observations of summertime Arctic cyclones, their coupling with cloud cover, and interactions with tropopause polar vortices and sea […]
Understanding the genetic and fitness consequences of anthropogenic bottlenecks is crucial for biodiversity conservation. However, studies of bottlenecked populations combining genomic approaches with fitness data are rare. Theory predicts that […]
This thesis utilises inverse and forward modelling of geophysical data to investigate the subglacial geology and influences on geothermal heat flow in northern Victoria Land and in Wilkes Subglacial Basin, […]
The reality of human-induced climate change is unequivocal and exerts an ever-increasing global impact. Access to the latest scientific information on current climate change and projection of future trends is […]
Salt is often present in the snow overlying seasonal sea ice, and has profound thermodynamic and electromagnetic effects. However, its provenance and behaviour within the snow remain uncertain. We describe […]
The 23–24 April 2023 double-peak (SYM-H intensities of −179 and −233 nT) intense geomagnetic storm was caused by interplanetary magnetic field southward component Bs associated with an interplanetary fast-forward shock-preceded […]
The embryonic development of marine ectotherms has been shown to be strongly temperature dependent across the world’s oceans. However, at the coldest sites, in the polar regions, development is even […]
The Antarctic Peninsula has experienced considerable anthropogenic warming in recent decades. While cryospheric responses are well defined, the responses of moss-dominated terrestrial ecosystems have not been quantified. Analysis of Landsat […]
The Dufek layered mafic intrusion represents the only exposed, deep-seated, part of the Ferrar Large Igneous Province, which extends >3500 km across Antarctica and into parts of Tasmania and New Zealand. […]
The high latitude ionospheric evolution of the May 10‐11, 2024, geomagnetic storm is investigated in terms of Total Electron Content and contextualized with Incoherent Scatter Radar and ionosonde observations. Substantial […]
Long-term reduction (∼20 km) in the height of the ionospheric F2 layer, hmF2, is predicted to result from increased levels of tropospheric greenhouse gases. Sufficiently long sequences of ionospheric data exist […]
