The radiative effect of a fir canopy on a snowpack
Models of snow processes in areas of possible large-scale change need to be site independent and physically based. Here, the accumulation and ablation of the seasonal snow cover beneath a […]

Foraging dynamics of macaroni penguins Eudyptes chrysolophus at South Georgia during brood-guard
Read more of: Foraging dynamics of macaroni penguins Eudyptes chrysolophus at South Georgia during brood-guardWe used satellite telemetry methods to study macaroni penguins at South Georgia to determine how they ranged from their colonies during the early part of their breeding season at a […]

Bacterioplankton composition in the Scotia Sea, Antarctica, during the austral summer of 2003
Read more of: Bacterioplankton composition in the Scotia Sea, Antarctica, during the austral summer of 2003Physical ocean processes (ice-melt, island run-off and upwelling of nutrients) were hypothesised to affect the bacterioplankton composition in the surface mixed layer of the Scotia Sea during the austral summer […]

The Greenland Ice Core Chronology 2005, 15–42 ka. Part 2: comparison to other records
Read more of: The Greenland Ice Core Chronology 2005, 15–42 ka. Part 2: comparison to other recordsA new Greenland Ice Core Chronology (GICC05) based on multi-parameter counting of annual layers has been obtained for the last 42 ka. Here we compare the glacial part of the […]

Polyphasic study of Antarctic cyanobacterial strains
Read more of: Polyphasic study of Antarctic cyanobacterial strainsWe isolated 59 strains of cyanobacteria from the benthic microbial mats of 23 Antarctic lakes, from five locations in two regions, in order to characterize their morphological and genotypic diversity. […]

Divergence time estimates for major cephalopod groups: evidence from multiple genes
Read more of: Divergence time estimates for major cephalopod groups: evidence from multiple genesThis is the first study to use both molecular and fossil data to date the divergence of taxa within the coleoid cephalopods (octopus, squid, cuttlefish). A dataset including sequences from […]

Bounce-averaged diffusion coefficients for field-aligned chorus waves
Read more of: Bounce-averaged diffusion coefficients for field-aligned chorus wavesWhistler mode chorus emissions in the Earth’s magnetosphere extend from the plasmapause to the boundary of trapping. Knowledge of the pitch angle and energy scattering rates is essential for accurate […]

The large-scale freshwater cycle of the Arctic
Read more of: The large-scale freshwater cycle of the ArcticThis paper synthesizes our understanding of the Arctic’s large-scale freshwater cycle. It combines terrestrial and oceanic observations with insights gained from the ERA-40 reanalysis and land surface and ice-ocean models. […]
