The influence of the Semi-Annual Oscillation (SAO) on the timing and evolution of major sudden stratospheric warmings (SSWs) is examined using the 2008/9 SSW as the primary case study. When […]
Arctic observing and data systems have been widely recognized as critical infrastructures to support decision making and understanding across sectors in the Arctic and globally. Yet due to broad and […]
Antarctica has been isolated and progressively glaciated for over 30 million years, with only approximately 0.3 % of its area currently ice-free and capable of supporting terrestrial ecosystems. As a […]
Seafloor biodiversity provides a key ecosystem service, as an efficient route for carbon to be removed from the atmosphere to become buried (long-term) in marine sediment. Protecting near intact ecosystems, […]
Climate-driven changes in disturbance are a major threat to ecosystem Functional diversity. The selective mechanisms underlying ecosystem response to disturbance are far from universal and remain the subject of scientific […]
The strong air temperature warming between the 1950s and 2016 in the Antarctic Peninsula region exceeded the global average warming with evident impacts on terrestrial ecosystems and the two native […]
The Antarctic continent, including its ice shelves, has an area of 13.8 million km2, about half the size of North America and 1.3 times the size of Europe. It is […]
Observations of surface lowering on Larsen C Ice Shelf (LCIS), Antarctica, have prompted concern about its stability. In this study, an ocean model is used to investigate the extent to […]
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 […]
