The silicon isotope composition (δ30Si) of dissolved silicon (DSi) and biogenic silica (BSi) provides information about the silicon cycle and its role in oceanic carbon uptake in the modern ocean […]
Rapid climatic changes in the western Antarctic Peninsula (WAP) have led to considerable changes in the meteoric freshwater input into the surrounding ocean, with implications for ocean circulation, the marine […]
The Byers Group, exposed on Byers Peninsula, Livingston Island and Snow Island, Antarctica, is a mudstone-dominated sequence deposited in a fore-arc setting. Palynological studies on parts of the Byers Group […]
In this paper we briefly describe the processes which lead to the formation of the Antarctic ozone hole, the attributes of the 1994 hole in comparison with previous years and […]
Dimethyl sulfide, methane sulfonate, non-sea-salt sulfate and sulfur dioxide concentrations in air were obtained during a cruise between the U.K. and the Antarctic during the period October 1992–January 1993. In […]
Carbon fixation under controlled conditions was measured in three mosses from the maritime Antarctic using an infra-red gas analysis system. Gas exchange parameters were determined during each season in 1993 […]
The light climate within wet and dry samples of ten mosses from the maritime Antarctic was determined using a computer-controlled optical microprobe system. Irradiances decreased with increasing depth within the […]
Fractal dimensions (D) of image perimeters of 4 macroalgae (Macrocystis pyrifera, Desmarestia menziesii, Schizoseris condensata, Palmaria georgica) collected at South Georgia, Southern Ocean were established over a wide scale range. […]
South Georgia, an extremely isolated island within the Antarctic Convergence, was covered by an extensive icecap until ~10,000 years ago. In consequence the depauperate intertidal fauna is of recent origin […]
