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 […]
Background/Objectives: We evaluated eukaryotic diversity in two cores obtained from abyssal sediments collected at depths of 4280 m and 4444 m in the equatorial Atlantic, between the Fernando de Noronha […]
Arctic sea ice is projected to thin and reduce in extent significantly over the next century. Both sea ice and its overlying snow limit the amount of light that reaches […]
Cryptotephra (non-visible volcanic ash) deposits in the Falkland Islands (Islas Malvinas) provide a distal record of South American volcanism and ash dispersal into the South Atlantic Ocean. Here, we present […]
This work aims to characterize the ionospheric disturbances in the South America – Antarctic Peninsula sector due the impact of a X1.3 solar event. This flare occurred on 30 March […]
The Amundsen Sea is dominated by a quasi-stationary low-pressure region, the Amundsen Sea Low (ASL). ASL variability impacts on regional weather and the basal melting of ice shelves, an important […]
Understanding the risk of introduction of marine non-native species requires data on pathways, including the level of biofouling present on vessels, vessel operating profiles and maintenance regimes. This study presents […]
Peter Fretwell is a senior scientist in the Mapping and Geographic Information Centre, at the British Antarctic Survey. Peter has pioneered the use of satellite imagery to study polar wildlife […]
