Recent intensification of extreme precipitation over East Antarctica driven by increases in greenhouse gases and stratospheric ozone
Read more of: Recent intensification of extreme precipitation over East Antarctica driven by increases in greenhouse gases and stratospheric ozoneExtreme precipitation is a major contributor to the total precipitation over Antarctica and its variability. However, it remains poorly understood whether Antarctic extreme precipitation has undergone recent changes and, if […]

The dynamic response of Pine Island Glacier to two decades of intermittent ice shelf regrounding
Read more of: The dynamic response of Pine Island Glacier to two decades of intermittent ice shelf regroundingOver the last few decades, ice keels have intermittently bumped against the bedrock underneath Pine Island Ice Shelf. In general, it is thought that this process, termed regrounding, could enhance […]

Provenance of continental blocks in the southern Scotia Sea using detrital zircon U-Pb geochronology
Read more of: Provenance of continental blocks in the southern Scotia Sea using detrital zircon U-Pb geochronologyReconstructions of the opening of the Scotia Sea and the Drake Passage oceanic gateway have traditionally been based on considerations of ocean spreading and rifting between crustal blocks, and geological […]

The source of Arctic precipitation in HadGEM3-GC5
Read more of: The source of Arctic precipitation in HadGEM3-GC5Snow and rain are increasing in the Arctic. Climate model projections indicate a 50% increase in precipitation by the end of the century. This increase is driven by increased local […]

Towards an improved understanding of the Antarctic coastal zone and its contribution to future global sea level
Read more of: Towards an improved understanding of the Antarctic coastal zone and its contribution to future global sea levelUnderstanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica’s influence on the global […]

Krill defecation at depth reduces carbon flux attenuation in the Weddell Sea euphotic zone
Read more of: Krill defecation at depth reduces carbon flux attenuation in the Weddell Sea euphotic zoneThe Weddell Sea, Southern Ocean, is a highly productive location of deep-water formation and a globally important site of carbon sequestration. Here, the biological carbon pump is dominated by carbon-rich […]

Spatial Variations in Surface Snow Chemistry and Stable Isotope Composition Along Different Transects of the Antarctic Coastal Zone
Read more of: Spatial Variations in Surface Snow Chemistry and Stable Isotope Composition Along Different Transects of the Antarctic Coastal ZoneThis study elucidated the spatial distribution characteristics of surface snow chemistry and stable isotope composition and their influencing factors in Antarctica’s coastal region. We analyzed data from eight surface snow […]

Microbial community structure in the firn associated with a ∼1000 km transect of the Eastern Antarctic Ice Sheet
Read more of: Microbial community structure in the firn associated with a ∼1000 km transect of the Eastern Antarctic Ice SheetThe surface snow and shallow ice of the Antarctic have traditionally been considered biologically inactive environments with low biomass. However, recent studies have begun to describe the complexity of microbial […]

Rb-Sr and U-Pb geochronology of neoblasts and porphyroclasts constrain movements along reactivated segments of the Outer Hebrides Fault Zone, NW Scotland
Read more of: Rb-Sr and U-Pb geochronology of neoblasts and porphyroclasts constrain movements along reactivated segments of the Outer Hebrides Fault Zone, NW ScotlandThe crustal-scale Outer Hebrides Fault Zone (OHFZ) (NW Scotland) was initiated as a Stenian-Tonian (1040-950 Ma) ductile thrust, as determined by published U-Pb dating of syn-kinematic apatite. Thrust-related mylonites were […]

Examining the Nuna-Rodinia supercontinent cycle in East Antarctica and testing correlations to the southwest United States: evidence from the Read Group (Shackleton Range) and the Nimrod Complex
Read more of: Examining the Nuna-Rodinia supercontinent cycle in East Antarctica and testing correlations to the southwest United States: evidence from the Read Group (Shackleton Range) and the Nimrod ComplexThe Read Group of the southern Shackleton Range and the Nimrod Complex of the central Transantarctic Mountains (cTAMs) form two cratonic blocks with unknown spatial extent and ambiguous crustal affinities.
