Decay of whistler-induced electron precipitation and cloud-ionosphere electrical discharge Trimpis: observations and analysis
Read more of: Decay of whistler-induced electron precipitation and cloud-ionosphere electrical discharge Trimpis: observations and analysisThere are two distinctly different causes of phase and amplitude perturbations of subionospheric VLF transmissions (termed “Trimpis”): (1) ionization enhancement in the ionospheric D region due to whistler-induced electron precipitation […]

Rutford Ice Stream, Antarctica
Read more of: Rutford Ice Stream, AntarcticaRutford Ice Stream is in many ways a typical Antarctic outlet glacier. Constrained by a subglacial-bed trough to the east of the Ellsworth Mountains, it drains an area of 49,000 […]

Palaeo-climatic and -biogeographical implications of Oligocene Ostracoda from CRP-2/2A and CRP-3 drillholes, Victoria Land basin, Antarctica
Read more of: Palaeo-climatic and -biogeographical implications of Oligocene Ostracoda from CRP-2/2A and CRP-3 drillholes, Victoria Land basin, AntarcticaA total of eighteen species of marine ostracods, in at least twelve genera, have been recovered from Early and Late Oligocene glacio-marine sediments from boreholes CRP-3 and CRP-2/2A in the […]

Drilling for Antarctic Cenozoic climate and tectonic history at Cape Roberts, southwestern Ross Sea
Read more of: Drilling for Antarctic Cenozoic climate and tectonic history at Cape Roberts, southwestern Ross SeaSince the early 1990s, the Cape Roberts Project has been working to document, through sediment drilling, the proximal record of Antarctic ice sheet history and climate for the southwestern part […]

High genetic diversity within Epimeria georgiana (Amphipoda) from the southern Scotia Arc
Read more of: High genetic diversity within Epimeria georgiana (Amphipoda) from the southern Scotia ArcDNA barcoding revealed four well-supported clades among amphipod specimens that keyed out to Epimeria georgiana Schellenberg, 1931, three clades with specimens from the southern Scotia Arc and one clade with […]

Schmidt Hammer studies in the maritime Antarctic: Application to dating Holocene deglaciation and estimating the effects of macrolichens on rock weathering
Read more of: Schmidt Hammer studies in the maritime Antarctic: Application to dating Holocene deglaciation and estimating the effects of macrolichens on rock weatheringIn order to contribute to the reconstruction of the deglaciation history of the Marguerite Bay area (~ 68°S, Maritime Antarctic) and to estimate the rock weathering rate in this Antarctic […]

The tectonic history of the Ellsworth Mountains, West Antarctica: reconciling a Gondwana enigma
Read more of: The tectonic history of the Ellsworth Mountains, West Antarctica: reconciling a Gondwana enigmaEarly Paleozoic orogenesis has been recognized along the southern African (Saldanian orogeny) and East Antarctic (Ross orogeny) sectors of the Gondwana paleo- Pacific margin. However, the absence of a contemporaneous […]

Taxonomic diversity gradients through geological time
Read more of: Taxonomic diversity gradients through geological timeThere is evidence from the fossil record to suggest that latitudinal gradients in taxonomic diversity may be time-invariant features, although almost certainly not on the same scale as that seen […]
