Palaeontological studies for CRP-3: introduction
The drillhole at CRP-3 was the deepest of the project and offered early hopes of retrieving a long plalaeontological record. However, the reality was that the fossil content dropped off […]

Methyl bromide, other brominated methanes, and methyl iodide in polar firn air
Read more of: Methyl bromide, other brominated methanes, and methyl iodide in polar firn airWe report measurements of brominated, bromochlorinated, and iodinated methanes in air extracted from deep firn at three polar locations (two Antarctic and one Arctic). Using a firn diffusion model, we […]

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 […]

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 […]
