Flow law for ice in polar ice sheets
Theories of glacier flow are based commonly on the assumption that ice is not a newtonian fluid, but has a non-linear stress-dependent viscosity1–5. Here we re-examine the spreading of Antarctic […]

Degradation of internal organic matter is the main control on pteropod shell dissolution after death
Read more of: Degradation of internal organic matter is the main control on pteropod shell dissolution after deathThe potential for preservation of thecosome pteropods is thought to be largely governed by the chemical stability of their delicate aragonitic shells in seawater. However, sediment trap studies have found […]

Dwarf brooder versus giant broadcaster: combining genetic and reproductive data to unravel cryptic diversity in an Antarctic brittle star
Read more of: Dwarf brooder versus giant broadcaster: combining genetic and reproductive data to unravel cryptic diversity in an Antarctic brittle starPoecilogony, or multiple developmental modes in a single species, is exceedingly rare. Several species described as poecilogenous were later demonstrated to be multiple (cryptic) species with a different developmental mode. […]

Trace elements in Antarctic air and snowfall
Read more of: Trace elements in Antarctic air and snowfallMeasurements of trace elements in snow and ice are frequently used to describe past atmospheric composition although there is no firm basis for assuming a direct connection. Trace-element concentrations have […]

The diet of the Southern rockhopper penguin Eudyptes chrysocome chrysocome at Beauchene Island, Falkland Islands
Read more of: The diet of the Southern rockhopper penguin Eudyptes chrysocome chrysocome at Beauchene Island, Falkland IslandsThe diet of the Southern rockhopper penguin at Beauchene Island, Falkland Islands, was studied in the early chick‐rearing period by quantitative analysis of adult stomach contents. Juvenile squid (Teuthowenia sp.) […]

Fur seal diving behaviour in relation to vertical distribution of krill
Read more of: Fur seal diving behaviour in relation to vertical distribution of krillQuantitative studies of predator-prey interactions depend on a knowledge of their spatial dynamics and behaviour. Studies on marine vertebrates have hitherto been precluded by the difficulty of acquiring the relevant […]
