Antarctic snow represents a microhabitat directly linked with atmospheric precipitation, and through it receives dust, sea spray, organic materials and microbial propagules. Among the microorganisms that inhabit Antarctic snow, fungi […]
The Ellsworth Mountains experience frigid desert conditions. No macroscopic vegetation is present, with only very few published records of microalgae, and the range has received virtually no formal biological survey. […]
Responses to the early (February–July 2020) COVID-19 pandemic varied widely, globally. Reasons for this are multiple but likely relate to the healthcare and financial resources then available, and the degree […]
It is challenging, yet important, to measure the – ever-changing – cold electron density in the plasmasphere. The cold electron density inside and outside of the plasmapause is a key […]
Mechanisms promoting coexistence between closely related species are fundamental for maintaining species diversity. Mechanisms of niche differentiation include allochrony which offsets the peak timing of resource utilisation between species. Many […]
The subglacial hydrological system exerts a critical control on the dynamic behaviour of the overlying ice because its configuration affects the degree of basal lubrication between the ice and the […]
Geomagnetically induced currents (GICs) produced during geomagnetic disturbances pose a risk to the safe operation of electrical power networks. One route to determine the hazard of large and extreme geomagnetic […]
Ice shelves restrict outflow from many of the largest glaciers in Antarctica, thus limiting the Antarctic contribution to sea-level rise. However, past ice-shelf collapse events show they are highly vulnerable […]
Blue carbon held in polar organisms has been little considered in terms of global carbon sinks and impacts on climate change. Although the magnitude of sinks is small compared with […]
Year-round observations of the physical snow and ice properties and processes that govern the ice pack evolution and its interaction with the atmosphere and the ocean were conducted during the […]
With the Arctic rapidly changing, the needs to observe, understand, and model the changes are essential. To support these needs, an annual cycle of observations of atmospheric properties, processes, and […]
In the present study, a Bayesian gravity inversion algorithm is applied to infer a complete 3D density model of the crust in the region of the Wilkes Land. One of […]
