Microbial and enzymatic activities were measured during the 49-day austral summer of 1991 in two fellfield soil polygons (WW-5 and WW-18) at Signy I. In 0-2.5 cm cores, microbial counts […]
Seventeen species of decapod crustaceans have been described from Campanian through Paleocene rocks in the Santa Marta, López de Bertodano, and Sobral Formations of the James Ross Basin, Antarctica. Of […]
A series of observations, using a dual-frequency calibrated echosounder operating at 38 and 120 kHz, of a patch of Euphausia superba close to South Georgia in 1986 is described. Sea […]
On South Georgia, two recently introduced species of predatory beetle,Oopterus soledadinus andTrechisibus antarcticus (Coleoptera, Carabidae), were studied in the period November 1991–April 1992. The study area comprised the coastal area […]
The nature of the coupling between the solar wind and magnetosphere on the dayside of the Earth, and the response of the ionosphere to this coupling are currently topics of […]
Antarctica is probably the least known of the world’s regions. Intensive research by over 20 nations during the past 30 years has demonstrated increasingly the integral and often critical role […]
Within the stable political context of the Antarctic Treaty regime, science has flourished, achieving considerable prominence and an increasing global relevance. Issues such as stratospheric ozone depletion and enhanced ultraviolet […]
Mass accumulations of belemnite rostra (‘belemnite battlefields’) are common in Mesozoic sediments, and accumulations of belemnoids are also known from older rocks. Many Recent teuthid species suffer mortality immediately after […]
The Mesozoic forearc of Alexander Island, Antarctica, is one of the few places in the world where the original stratigraphic relationship between a forearc basin and an accretionary complex is […]
