Thwaites Glacier in West Antarctica has been identified as a route to destabilization of the whole West Antarctic Ice Sheet, potentially leading to several meters of sea‐level rise. However, future […]
Geomagnetically Induced Currents (GICs) in grounded, conducting infrastructure (e.g., power networks) represent an important space weather hazard. GICs are driven by the changing magnetic field at the Earth’s surface. Due […]
Changes in the hydrological cycle can affect ocean circulation and ventilation. Freshwater enters the ocean as meteoric water (MW; precipitation, river runoff, and glacial discharge) and sea ice meltwater (SIM). […]
Imagers that observe optical or ultraviolet emissions from the atmosphere are commonly used to identify and study ionospheric phenomena. These phenomena include the auroral oval, equatorial plasma bubbles, and traveling […]
Monitoring of seabird population size and demography has for decades relied on observer-based methods. While such methods have allowed the accumulation of extensive, standardized time series, while typically involving both […]
Given that the Arctic could be ice-free in summer within the next ten to twenty years, accurately predicting low-ice states is of crucial importance. Paleo-evidence shows that the strong orbitally-induced […]
We present a new 1:500 000 geological map of Alexander Island of West Antarctica. The map, combined with recent detrital zircon analysis, defines an updated chronostratigraphy for the Fossil Bluff […]
Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are a group of temperature-sensitive membrane lipids found in bacteria that have been widely used in palaeo-temperature reconstruction. Despite recent advances in analytical methods, […]
Several general circulation models have now demonstrated the ability to simulate spontaneous millennial-scale oscillations that resemble Dansgaard–Oeschger (DO) events. It is often unclear how representative of DO events these simulations […]
Snow algae form extensive blooms within Antarctica’s coastal snowpacks and are a crucial contributor to its scarce terrestrial ecosystems. There is limited knowledge about the factors that contribute to snow […]
Polar Winter Climate and Processes: Towards Filling Knowledge Gaps in the Understanding of the Coupled Climate System Recordings: Over 110 participants registered for this hybrid workshop, from 18 countries representing […]
The sub-Antarctic and polar fronts are features of the Antarctic Circumpolar Current that separates the South Atlantic and Southern Ocean. These fronts act as both a physical and physiological barrier […]
