Between 15 and 19 March 2022, East Antarctica experienced an exceptional heat wave with widespread 30°–40°C temperature anomalies across the ice sheet. In Part I, we assessed the meteorological drivers […]
Between 15 and 19 March 2022, East Antarctica experienced an exceptional heat wave with widespread 30°–40°C temperature anomalies across the ice sheet. This record-shattering event saw numerous monthly temperature records […]
Snow is a unique microhabitat, despite being a harsh environment, multiple life forms have adapted to survive in it. While algae, bacteria and fungi are dominant microorganisms in Antarctic snow, […]
Nests of the icefish Chionodraco hamatus were documented for the first time at about 500 m depth at Terra Nova Bay (Victoria Land, western Ross Sea), in an area included […]
To refine moisture-source and site-temperature reconstructions inferred from measurements from ice cores, we must understand moisture provenance from which Antarctic precipitation originates. Here, we discuss our current understanding of Antarctic […]
The impact of melt ponds on sea-ice albedo has been observed and documented. In general circulation models, ponds are now accounted for through indirect diagnostic treatments (‘implicit’ schemes), or prognostic […]
Stable water isotope records of six firn cores retrieved from two adjacent plateaus on the northern Antarctic Peninsula between 2014 and 2016 are presented and investigated for their connections with […]
Meteorological records at Signy Station in the South Orkney Islands (SOIs) have recently been digitized to cover the period of 1947–1995. This study compares the newly available near-surface air temperatures […]
Ocean deoxygenation due to anthropogenic warming represents a major threat to marine ecosystems and fisheries. Challenges remain in simulating the modern observed changes in the dissolved oxygen (O2). Here, we […]
Mercury (Hg) is a globally important pollutant that can negatively impact metabolic, endocrine and immune systems of marine biota. Seabirds are long-lived marine top predators and hence are at risk […]
The Atlantic multidecadal oscillation (AMO) is considered as one of the major drivers of Indian Summer monsoon (ISM) multidecadal variability. The teleconnection is thought to take place via two dominant […]
