Observations on the distribution and relative abundance of the scyphomedusan Chrysaora hysoscella (Linne, 1766) and the hydrozoan Aequorea aequorea (Forskal, 1775) in the northern Benguela ecosystem
Read more of: Observations on the distribution and relative abundance of the scyphomedusan Chrysaora hysoscella (Linne, 1766) and the hydrozoan Aequorea aequorea (Forskal, 1775) in the northern Benguela ecosystemObservations on the abundance of medusae at the surface were conducted in the northern Benguela ecosystem, over the period August 1997–June 1998. The results suggest that Chrysaora hysoscella is found […]

A quantitative estimate of the ducted whistler power within the outer plasmasphere
Read more of: A quantitative estimate of the ducted whistler power within the outer plasmasphereFrom a statistical study of ductedwhistlers observed at Halley, Antarctica, in 1996, which had propagated on paths in the range L=2.5–4.5, we report mean occurrence rates, numbers of components per […]

Whistler observations of the plasmasphere/plasmapause from stations of the British Antarctic Survey
Read more of: Whistler observations of the plasmasphere/plasmapause from stations of the British Antarctic SurveyVLF whistler observations from Eights Station, Antarctica were crucial to the discovery and exploration of the plasmapause (”Carpenter’s knee”) by Don Carpenter in the mid-1960s. The Weddell Sea sector of […]

Geochemical characteristics and geotectonic setting of early Ordovician basalt lavas in the Ballantrae Complex ophiolite, SW Scotland
Read more of: Geochemical characteristics and geotectonic setting of early Ordovician basalt lavas in the Ballantrae Complex ophiolite, SW ScotlandThe consensus of several geochemical studies is a polygenetic origin for the basic volcanic sequence within the Ballantrae Complex ophiolite. This overall agreement masks differences of opinion regarding local geochemical […]

Lithofacies Architecture and Construction of Volcanoes Erupted in Englacial Lakes: Icefall Nunatak, Mount Murphy, Eastern Marie Byrd Land, Antarctica
Read more of: Lithofacies Architecture and Construction of Volcanoes Erupted in Englacial Lakes: Icefall Nunatak, Mount Murphy, Eastern Marie Byrd Land, AntarcticaMount Murphy is a large Miocene shield volcano flanked by several small basaltic satellite centres that were erupted beneath a thick (> 200 m) ice sheet. Three empirical models illustrating […]

History of Oligocene erosion, uplift and unroofing of the Transantarctic Mountains deduced from sandstone detrital modes in CRP-3 drillcore, Victoria Land basin, Antarctica
Read more of: History of Oligocene erosion, uplift and unroofing of the Transantarctic Mountains deduced from sandstone detrital modes in CRP-3 drillcore, Victoria Land basin, AntarcticaDetrital modes determined on 68 sandstone samples from CRP-3 drillcore indicate a continuation of the dynamic history of uplift-related erosion and unroofing previously documented in CRP-1 and CRP-2/2A. The source […]

Physical, chemical and biological processes in Lake Vostok and other Antarctic subglacial lakes
Read more of: Physical, chemical and biological processes in Lake Vostok and other Antarctic subglacial lakesOver 70 lakes have now been identi®ed beneath the Antarctic ice sheet. Although water from none of the lakes has been sampled directly, analysis of lake ice frozen (accreted) to […]
