Antarctic marine biology
Antarctica is a continent of extremes: on average it is the highest, windiest, coldest and driest land mass on Earth. It also has the largest ice-mass, with less than 1% […]

Flow at ice-divide triple junctions: 1. Three-dimensional full-Stokes modeling
Read more of: Flow at ice-divide triple junctions: 1. Three-dimensional full-Stokes modelingIce domes are either axisymmetric, high points along ridges, or ridge triple junctions. We model time-dependent isothermal flow near triple junctions, solving the full set of mechanical equations with a […]

A technique for the examination of polar ice using the scanning electron microscope
Read more of: A technique for the examination of polar ice using the scanning electron microscopeThe microstructure and location of impurities in polar ice are of great relevance to ice core studies. We describe a reliable method to examine ice in the scanning electron microscope […]

Invasions by marine life on plastic debris
Read more of: Invasions by marine life on plastic debrisColonization by alien species poses one of the greatest threats to global biodiversity1. Here I investigate the colonization by marine organisms of drift debris deposited on the shores of 30 […]

Hermit crabs, humans and crowded house markets
Read more of: Hermit crabs, humans and crowded house marketsThere is a complex and dynamic interrelationhip between hermit crabs, humans and the coastal environment. Hermit crab homes (shells) are often hard to come by, but humans are helping out […]

Clade perseverance from mesozoic to present: a multidisciplinary approach to interpretation of pattern and process
Read more of: Clade perseverance from mesozoic to present: a multidisciplinary approach to interpretation of pattern and processTwo clades of marine bryozoans, cyclostomes and cheilostomes, exemplify the benefits of applying a multidisciplinary approach to the interpretation of long-term evolutionary patterns. The cyclostome bryozoans were dominant in the […]

Seasonal and interannual variation in foraging range and habitat of macaroni penguins Eudyptes chrysolophus at South Georgia
Read more of: Seasonal and interannual variation in foraging range and habitat of macaroni penguins Eudyptes chrysolophus at South GeorgiaIn marine ecosystems, characterisation of the foraging areas and habitats of predators is a key factor in interpreting their ecological role, We studied the foraging areas of the macaroni penguin […]

Provisioning behaviour of macaroni penguins Eudyptes chrysolophus
Read more of: Provisioning behaviour of macaroni penguins Eudyptes chrysolophusUnderstanding how parental expenditure reflects food availability and influences reproductive output is a key part of studies of breeding performance. Provisioning behaviour is an important aspect of parental expenditure. We […]

Data report: Composite depths and spliced sections for Leg 178 Sites 1095 and 1096, Antarctic Peninsula continental rise
Read more of: Data report: Composite depths and spliced sections for Leg 178 Sites 1095 and 1096, Antarctic Peninsula continental riseDuring Leg 178, multiple advanced piston corer holes were drilled at our sites (1095, 1096, 1098, and 1099). Cores from the holes were correlated on board to produce composite depths […]

Antarctic glacial history and sea-level change
Read more of: Antarctic glacial history and sea-level changeThe Pacific margin of the Antarctic Peninsula was drilled during Ocean Drilling Program (ODP) Leg 178 to understand the past 10 m.y. of its glacial history and to test a […]

Length-at-age in juvenile Patagonian toothfish (Dissostichus eleginoides)
Read more of: Length-at-age in juvenile Patagonian toothfish (Dissostichus eleginoides)We used the otoliths from a sample of Dissostichus eleginoides pre-recruits, whose length density was distinctly polymodal, to see whether ages estimated by reading otoliths were congruent with the length […]
