Low frequency variability of Southern Ocean jets
Both observations and high resolution numerical models show that the Southern Ocean circumpolar flow is concentrated in a large number (approximately 8 to 12) of narrow filamentary jets. It is […]

Cephalopods in marine predator diet assessments: why identifying upper and lower beaks is important
Read more of: Cephalopods in marine predator diet assessments: why identifying upper and lower beaks is importantCephalopods are components of the diet of many predators worldwide. They are identified mainly using their chitinized upper and lower beaks, but because it has been assumed that the number […]

Sexual segregation in distribution, diet and trophic level of seabirds: insights from stable isotope analysis
Read more of: Sexual segregation in distribution, diet and trophic level of seabirds: insights from stable isotope analysisConsiderable attention has focused on inter- and intraspecific variation in trophic niches of marine predators. Although this has revealed evidence for sexual segregation in distribution in some species, few studies […]

Extracellular hydrolase enzyme production by soil fungi from King George Island, Antarctica
Read more of: Extracellular hydrolase enzyme production by soil fungi from King George Island, AntarcticaVarious microbial groups are well known to produce a range of extracellular enzymes and other secondary metabolites. However, the occurrence and importance of investment in such activities have received relatively […]

Reduced survival of Antarctic benthos linked to climate-induced iceberg scouring
Read more of: Reduced survival of Antarctic benthos linked to climate-induced iceberg scouringThe West Antarctic Peninsula (WAP) is a hotspot of recent rapid regional warming and ice loss1. The WAP sea surface freezes each winter to form a ‘fast-ice’ skin that can […]

Recent developments in the radiation belt environment model
Read more of: Recent developments in the radiation belt environment modelThe fluxes of energetic particles in the radiation belts are found to be strongly controlled by the solar wind conditions. In order to understand and predict the radiation particle intensities, […]

Centennial- to millennial-scale ice-ocean interactions in the subpolar Northeast Atlantic 18-41 kyr ago
Read more of: Centennial- to millennial-scale ice-ocean interactions in the subpolar Northeast Atlantic 18-41 kyr agoIn order to monitor the evolution of the British-Irish Ice Sheet (BIIS) and its influence in surface ocean structure during marine isotopic stages (MIS) 2 and 3, we have analyzed […]

The diet of toothfish species Dissostichus eleginoides and Dissostichus mawsoni with overlapping distributions
Read more of: The diet of toothfish species Dissostichus eleginoides and Dissostichus mawsoni with overlapping distributionsThe diets of Antarctic toothfish Dissostichus mawsoni and Patagonian toothfish Dissostichus eleginoides were examined around the South Sandwich Islands in the Southern Ocean, one of few regions with overlapping populations […]

Movements and wintering areas of breeding age Thick-billed Murre Uria lomvia from two colonies in Nunavut, Canada
Read more of: Movements and wintering areas of breeding age Thick-billed Murre Uria lomvia from two colonies in Nunavut, CanadaThe non-breeding movements of marine birds were poorly known until recently, but this information is essential to understanding the risk to different geographical populations from events on the wintering grounds.
