Sensitivity of melting, freezing and marine ice beneath Larsen C Ice Shelf to changes in ocean forcing
Read more of: Sensitivity of melting, freezing and marine ice beneath Larsen C Ice Shelf to changes in ocean forcingObservations 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 […]

Fungal diversity in seasonal snow of Martel Inlet, King George Island, South Shetland Islands, assessed using DNA metabarcoding
Read more of: Fungal diversity in seasonal snow of Martel Inlet, King George Island, South Shetland Islands, assessed using DNA metabarcodingAntarctic 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 […]

Diversity of Viridiplantae DNA present on rock surfaces in the Ellsworth Mountains, continental Antarctica
Read more of: Diversity of Viridiplantae DNA present on rock surfaces in the Ellsworth Mountains, continental AntarcticaThe 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. […]

An exploration of the political, social, economic and cultural factors affecting how different global regions initially reacted to the COVID-19 pandemic
Read more of: An exploration of the political, social, economic and cultural factors affecting how different global regions initially reacted to the COVID-19 pandemicResponses 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 […]

Monitoring space weather: using automated, accurate neural network based whistler segmentation for whistler inversion
Read more of: Monitoring space weather: using automated, accurate neural network based whistler segmentation for whistler inversionIt 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 […]

The role of allochrony in influencing interspecific differences in foraging distribution during the non-breeding season between two congeneric crested penguin species
Read more of: The role of allochrony in influencing interspecific differences in foraging distribution during the non-breeding season between two congeneric crested penguin speciesMechanisms 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 […]

Subglacial water flow over an Antarctic palaeo-ice stream bed
Read more of: Subglacial water flow over an Antarctic palaeo-ice stream bedThe 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 current model in New Zealand across multiple disturbances: Validation and extension to non‐monitored transformers
Read more of: Geomagnetically induced current model in New Zealand across multiple disturbances: Validation and extension to non‐monitored transformersGeomagnetically 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 […]

Basal melting, roughness and structural integrity of ice shelves
Read more of: Basal melting, roughness and structural integrity of ice shelvesIce 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 Sinks on Polar Seabeds and Their Feedbacks on Climate Change
Read more of: Blue Carbon Sinks on Polar Seabeds and Their Feedbacks on Climate ChangeBlue 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 […]
