West Antarctic Ice Sheet collapse – the fall and rise of a paradigm
It is now almost 30 years since John Mercer (1978) first presented the idea that climate change could eventually cause a rapid deglaciation, or “collapse”, of a large part of […]

Trade-offs in thermal adaptation: the need for a molecular to ecological integration
Read more of: Trade-offs in thermal adaptation: the need for a molecular to ecological integrationThrough functional analyses, integrative physiology is able to link molecular biology with ecology as well as evolutionary biology and is thereby expected to provide access to the evolution of molecular, […]

Low potential for stratospheric dynamical change to be implicated in the large winter warming in the central Antarctic Peninsula
Read more of: Low potential for stratospheric dynamical change to be implicated in the large winter warming in the central Antarctic PeninsulaStratospheric change associated with the Antarctic ozone hole is clearly implicated in changing surface climate near 65°S in late summer, in both measurements and models, via downward propagation of height […]

Switch-off of a major enhanced ice flow unit in East Antarctica
Read more of: Switch-off of a major enhanced ice flow unit in East AntarcticaThe East Antarctic Ice Sheet (EAIS) is the largest reservoir of ice on the planet by an order of magnitude. Compared with the West Antarctic Ice Sheet (WAIS), it is […]

The atmospheric implications of radiation belt remediation
Read more of: The atmospheric implications of radiation belt remediationHigh altitude nuclear explosions (HANEs) and geomagnetic storms can produce large scale injections of relativistic particles into the inner radiation belts. It is recognised that these large increases in >1 […]

From cradle to early grave: juvenile mortality in European shags Phalacrocorax aristotelis results from inadequate development of foraging proficiency
Read more of: From cradle to early grave: juvenile mortality in European shags Phalacrocorax aristotelis results from inadequate development of foraging proficiencyIn most long-lived animal species, juveniles survive less well than adults. A potential mechanism is inferior foraging skills but longitudinal studies that follow the development of juvenile foraging are needed […]

Growth rate and its variability in erect Antarctic bryozoans
Read more of: Growth rate and its variability in erect Antarctic bryozoansClimate is altering rapidly in parts of the Arctic and Antarctic but we know little about how marine organisms are responding to, or might respond to such changes. Knowledge of […]

A new species of Pareledone (Cephalopoda: Octopodidae) from Antarctic Peninsula Waters
Read more of: A new species of Pareledone (Cephalopoda: Octopodidae) from Antarctic Peninsula WatersDuring recent cruises aboard RV Polarstern in the Antarctic Peninsula region, a new species of benthic octopodid was discovered whose generic affinities based on morphological characteristics were uncertain. Molecular sequence […]

Acceleration mechanism responsible for the formation of the new radiation belt during the 2003 Halloween solar storm
Read more of: Acceleration mechanism responsible for the formation of the new radiation belt during the 2003 Halloween solar stormObservations of the relativistic electron flux increases during the first days of November, 2003 are compared to model simulations of two leading mechanisms for electron acceleration. It is demonstrated that […]

Subglacial geology in Coats Land, East Antarctica, revealed by airborne magnetics and radar sounding
Read more of: Subglacial geology in Coats Land, East Antarctica, revealed by airborne magnetics and radar soundingDuring the austral summer of 2001/02 five thousand line kilometres of airborne radio echo sounding and aeromagnetic data were collected in the region of three tributaries of Slessor Glacier, East […]
