Downslope föhn winds over the Antarctic Peninsula and their effect on the Larsen Ice Shelves
Read more of: Downslope föhn winds over the Antarctic Peninsula and their effect on the Larsen Ice ShelvesMesoscale model simulations are presented of a westerly föhn event over the Antarctic Peninsula mountain ridge and onto the Larsen C ice shelf, just south of the recently collapsed Larsen […]

Surface-water iron supplies in the Southern Ocean sustained by deep winter mixing
Read more of: Surface-water iron supplies in the Southern Ocean sustained by deep winter mixingLow levels of iron limit primary productivity across much of the Southern Ocean. At the basin scale, most dissolved iron is supplied to surface waters from subsurface reservoirs, because land […]

Marine moult migration of the freshwater Scaly-sided Merganser Mergus squamatus revealed by stable isotopes and geolocators
Read more of: Marine moult migration of the freshwater Scaly-sided Merganser Mergus squamatus revealed by stable isotopes and geolocatorsScaly-sided Mergansers Mergus squamatus breed on freshwater rivers in far eastern Russia, Korea and China, wintering in similar habitats in China and Korea, but nothing was known of their moulting […]

Foraging zones of the two sibling species of giant petrels in the Indian Ocean throughout the annual cycle: implication for their conservation
Read more of: Foraging zones of the two sibling species of giant petrels in the Indian Ocean throughout the annual cycle: implication for their conservationWe studied the year-round distribution and at-sea activity patterns of the sibling species, northern giant petrel Macronectes halli and southern giant petrel M. giganteus. Loggers combining light-based geolocators and immersion […]

What shall I do now? State-dependent variations of life-history traits with aging in Wandering Albatrosses
Read more of: What shall I do now? State-dependent variations of life-history traits with aging in Wandering AlbatrossesAllocation decisions depend on an organism’s condition which can change with age. Two opposite changes in life-history traits are predicted in the presence of senescence: either an increase in breeding […]

Modelling the coupling of flood discharge with glacier flow during jökulhlaups
Read more of: Modelling the coupling of flood discharge with glacier flow during jökulhlaupsWe explore a mathematical model that couples together a thermomechanically evolving subglacial channel, distributed cavity drainage, and basal sliding along a subglacial flood path fed by a jökulhlaup lake. It […]

Millennial timescale regeneration in a moss from Antarctica
Read more of: Millennial timescale regeneration in a moss from AntarcticaMosses, dominant elements in the vegetation of polar and alpine regions, have well-developed stress tolerance features permitting cryptobiosis. However, direct regeneration after longer periods of cryptobiosis has been demonstrated only […]

Areas of importance for seabirds tracked from French southern territories, and recommendations for conservation
Read more of: Areas of importance for seabirds tracked from French southern territories, and recommendations for conservationSeabirds are increasingly threatened worldwide, with population declines for many species that are faster than in any other group of birds. Here the Important Bird Area (IBA) criteria recommended by […]

First optical observations of energetic electron precipitation at 4278 Å caused by a powerful VLF transmitter
Read more of: First optical observations of energetic electron precipitation at 4278 Å caused by a powerful VLF transmitterA summary is presented of experimental optical observations at 4278 Å from close to a powerful (~150 kW) VLF transmitter (call-sign JXN) with a transmission frequency of 16.4 kHz. Approximately […]

Terrestrial and submarine evidence for the extent and timing of the Last Glacial Maximum and the onset of deglaciation on the maritime-Antarctic and sub-Antarctic islands
Read more of: Terrestrial and submarine evidence for the extent and timing of the Last Glacial Maximum and the onset of deglaciation on the maritime-Antarctic and sub-Antarctic islandsThis paper is the maritime and sub–Antarctic contribution to the Scientific Committee for Antarctic Research (SCAR) Past Antarctic Ice Sheet Dynamics (PAIS) community Antarctic Ice Sheet reconstruction. The overarching aim […]
