Evidence for an extended reconnection line at the dayside magnetopause
Read more of: Evidence for an extended reconnection line at the dayside magnetopauseWe report in-situ detection by two spacecraft of oppositely directed jets of plasma emanating from a magnetic reconnection site at the Earth’s dayside magnetopause, confirming a key element inherent in […]

Rates of assay success and genotyping error when single nucleotide polymorphism genotyping in non-model organisms: a case study in the Antarctic fur seal
Read more of: Rates of assay success and genotyping error when single nucleotide polymorphism genotyping in non-model organisms: a case study in the Antarctic fur sealAlthough single nucleotide polymorphisms (SNPs) are increasingly being recognized as powerful molecular markers, their application to non-model organisms can bring significant challenges. Among these are imperfect conversion rates of assays […]

Feeding, metabolism and growth in the Antarctic limpet, Nacella concinna (Strebel 1908)
Read more of: Feeding, metabolism and growth in the Antarctic limpet, Nacella concinna (Strebel 1908)Post-prandial increases in metabolism, the specific dynamic action of feeding (SDA), were evaluated in the Antarctic limpet Nacella concinna. O2 consumption rose to a peak value 2.3 times higher than pre-feeding […]

Geochemical tracing of Pacific-to-Atlantic upper-mantle flow through the Drake passage
Read more of: Geochemical tracing of Pacific-to-Atlantic upper-mantle flow through the Drake passageThe Earth’s convecting upper mantle can be viewed as comprising three main reservoirs, beneath the Pacific, Atlantic and Indian oceans. Because of the uneven global distribution and migration of ridges […]

Co-variation of crenarchaeol and branched GDGTs in globally-distributed marine and freshwater sedimentary archives
Read more of: Co-variation of crenarchaeol and branched GDGTs in globally-distributed marine and freshwater sedimentary archivesTwo major types of glycerol dialkyl glycerol tetraethers (GDGTs) are commonly used in paleoecological and paleoclimatological reconstructions: isoprenoidal and branched GDGTs. In aquatic environments, it was originally assumed that isoprenoidal […]

On the winding of auroral spirals: Interhemispheric observations and Hallinan’s theory revisited
Read more of: On the winding of auroral spirals: Interhemispheric observations and Hallinan’s theory revisitedAuroral spirals are the largest vortex structures that appear in auroral arcs. Their diameters vary from tens to hundreds of kilometers. We have collected an all-sky camera data set of […]

Age and origin of coeval TTG, I- and S-type granites in the Famatinian belt of NW Argentina
Read more of: Age and origin of coeval TTG, I- and S-type granites in the Famatinian belt of NW ArgentinaThree granitoid types are recognised in the Famatinian magmatic belt of NW Argentina, based on lithology and new geochemical data: (a) a minor trondhjemite–tonalite–granodiorite (TTG) group, (b) a metaluminous I-type […]

Using tephrochronology to date temperate ice: correlation between ice tephras on Livingston Island and eruptive units on Deception Island volcano (South Shetland Islands, Antarctica)
Read more of: Using tephrochronology to date temperate ice: correlation between ice tephras on Livingston Island and eruptive units on Deception Island volcano (South Shetland Islands, Antarctica)Tephra layers are interstratified in the ice caps of the South Shetland Islands. Although previously poorly investigated, they are potential targets for the application of tephrochronology and, hence, may provide […]
