Characterizing ice sheets during the Pliocene: evidence from data and models
The Pliocene (c. 5.3 – 1.8 Myr BP) was the last epoch of geological time in which global temperatures were generally higher than modern. It is important if we are […]

Remote sensing of the spatial and temporal structure of magnetopause and magnetotail reconnection from the ionosphere
Read more of: Remote sensing of the spatial and temporal structure of magnetopause and magnetotail reconnection from the ionosphereMagnetic reconnection is the most significant process that results in the transport of magnetised plasma into, and out of, the Earth’s magnetosphere-ionosphere system. There is also compelling observational evidence that […]

Elevated UV-B radiation modifies the extractability of carbohydrates from leaf litter of Quercus robur
Read more of: Elevated UV-B radiation modifies the extractability of carbohydrates from leaf litter of Quercus roburWe examined the influence of elevated UV-B radiation on the extractability of carbohydrates from leaf litter of Quercus robur. Saplings were exposed to a 30% elevation above the ambient level […]

Basal conditions beneath enhanced-flow tributaries of Slessor Glacier, East Antarctica
Read more of: Basal conditions beneath enhanced-flow tributaries of Slessor Glacier, East AntarcticaRadio-echo sounding data are used to investigate bed roughness beneath the three enhanced-flow tributaries of Slessor Glacier, East Antarctica. Slow-moving inter-tributary areas are found to have rough beds, while the […]

Circumpolar connections between Antarctic krill (Euphausia superba Dana) populations: investigating the roles of ocean and sea ice transport
Read more of: Circumpolar connections between Antarctic krill (Euphausia superba Dana) populations: investigating the roles of ocean and sea ice transportAntarctic krill, Euphausia superba Dana, has a heterogeneous circumpolar distribution in the Southern Ocean. Krill have a close association with sea ice which provides access to a critical food source […]

Variability in the freshwater balance of northern Marguerite Bay, Antarctic Peninsula: results from δ18O
Read more of: Variability in the freshwater balance of northern Marguerite Bay, Antarctic Peninsula: results from δ18OWe investigate the seasonal variability in freshwater inputs to the Marguerite Bay region (Western Antarctic Peninsula) using a time series of oxygen isotopes in seawater from samples collected in the […]

On the interannual variability of ocean temperatures around South Georgia, Southern Ocean: forcing by El Niño/Southern Oscillation and the Southern Annular Mode
Read more of: On the interannual variability of ocean temperatures around South Georgia, Southern Ocean: forcing by El Niño/Southern Oscillation and the Southern Annular ModeThe ocean around South Georgia, in the southwest Atlantic sector of the Southern Ocean, is highly productive, with large stocks of Antarctic krill supporting extensive colonies of marine and land-based […]

Eddy heat flux in the Southern Ocean: response to variable wind forcing
Read more of: Eddy heat flux in the Southern Ocean: response to variable wind forcingWe assess the role of time-dependent eddy variability in the Antarctic Circumpolar Current (ACC) in influencing warming of the Southern Ocean. For this, we use an eddy-resolving quasigeostrophic model of […]

Monitoring Drake Passage with elephant seals: frontal structures and snapshots of transport
Read more of: Monitoring Drake Passage with elephant seals: frontal structures and snapshots of transportCTD-Satellite Relay Data Loggers (CTD-SRDLs), each recording conductivity, temperature and pressure, were attached to Southern elephant seals (Mirounga leonina) on the island of South Georgia. During the animals’ migration the […]

Unlocking the time capsule of historic aerial photography to measure changes in Antarctic Peninsula glaciers
Read more of: Unlocking the time capsule of historic aerial photography to measure changes in Antarctic Peninsula glaciersRecent studies have reported widespread retreat and acceleration of glaciers on the Antarctic Peninsula, attributed to regional warming. The loss of ice is a contributor to sea-level rise, but its […]
