Territoriality and breeding behaviour of adult male Antarctic fur seal, Arctocephalus gazella
Read more of: Territoriality and breeding behaviour of adult male Antarctic fur seal, Arctocephalus gazellaThe social organization and behaviour of 35 individually recognizable territorial male Antarctic Fur seals (Arctocephalus guzellu), were studied during the breeding season at South Georgia. Adults of both sexes remain […]

Stabilization of dense Antarctic water supply to the Atlantic Ocean overturning circulation
Read more of: Stabilization of dense Antarctic water supply to the Atlantic Ocean overturning circulationThe lower limb of the Atlantic overturning circulation is resupplied by the sinking of dense Antarctic Bottom Water (AABW) that forms via intense air–sea–ice interactions next to Antarctica, especially in […]

Read more of: The penultimate deglaciation: protocol for Paleoclimate Modelling Intercomparison Project (PMIP) phase 4 transient numerical simulations between 140 and 127 ka, version 1.0The penultimate deglaciation (PDG, ∼138–128 thousand years before present, hereafter ka) is the transition from the penultimate glacial maximum (PGM) to the Last Interglacial (LIG, ∼129–116 ka). The LIG stands out as […]
