Magnetic local time‐resolved examination of radiation belt dynamics during high speed solar wind speed triggered substorm clusters
Read more of: Magnetic local time‐resolved examination of radiation belt dynamics during high speed solar wind speed triggered substorm clustersParticle observations from low Earth orbiting satellites are used to undertake superposed epoch analysis around clusters of substorms, in order to investigate radiation belt dynamical responses to mild geomagnetic disturbances.

Temporal variability in foraminiferal morphology and geochemistry at the West Antarctic Peninsula: a sediment trap study
Read more of: Temporal variability in foraminiferal morphology and geochemistry at the West Antarctic Peninsula: a sediment trap studyThe West Antarctic Peninsula (WAP) exhibits strong spatial and temporal oceanographic variability, resulting in highly heterogeneous biological productivity. Calcifying organisms that live in the waters off the WAP respond to […]

Morphology and dynamics of ice rises
Read more of: Morphology and dynamics of ice risesProfile surveys are presented of four ice rises on the east coast of the Antarctic Peninsula. On Butler Island velocity measurements were also made. The ice rises behave as miniature […]

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 […]

Population structure and social organization of southern elephant seals, Mirounga leonina (L.)
Read more of: Population structure and social organization of southern elephant seals, Mirounga leonina (L.)The population structure and social organization of the Southern Elephant Seal, Mirounga leonina, were studied at South Georgia principally by extensive field census work and determination of age and reproductive […]

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 […]

Physiological and thylakoid ultrastructural changes in cyanobacteria in response to toxic manganese concentrations
Read more of: Physiological and thylakoid ultrastructural changes in cyanobacteria in response to toxic manganese concentrationsIn this study, two cyanobacterial strains (morphologically identified as Microcystis novacekii BA005 and Nostoc paludosum BA033) were exposed to different Mn concentrations: 7.0, 10.5, 15.7, 23.6 and 35.4 mg L−1 for BA005; […]

The penultimate deglaciation: protocol for Paleoclimate Modelling Intercomparison Project (PMIP) phase 4 transient numerical simulations between 140 and 127 ka, version 1.0
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 […]

Applying science to pressing conservation needs for penguins
Read more of: Applying science to pressing conservation needs for penguinsMore than half of the world’s 18 penguin species are declining. We, the Steering Committee of the International Union for Conservation of Nature Species Survival Commission Penguin Specialist Group, determined […]
