Interannual variation in aspects of the breeding biology of Antarctic prions was studied for three summers (1989–1992) at Bird island, South Georgia. Egg size, mass and incubation period remained constant. […]
Visible spectra of the zenith-sky were recorded at Faraday in Antartica during 1990. Line-of-sight NO2 amounts were deduced by fitting laboratory cross-sections to the spectra. A new procedure was used […]
From at least the Early Jurassic to the Miocene, eastward subduction of oceanic crust took place beneath the Antarctic Peninsula. Magmatism associated with the subduction generated a N-S linear belt […]
The effects of cytochalasin B and dimethyl sulphoxide (DMSO) on ciliate ingestion and growth were investigated in laboratory cultures of the freshwater ciliate Tetrahymena pyriformis and the marine ciliate Uronema […]
The abundance and biomass of marine planktonic ciliates in Borge Bay, Signy Island, were determined at monthly intervals between April 1990 and June 1991. At least 24 different ciliate taxa […]
The diet composition and feeding intensity of mackerel icefish Champsocephalus gunnari around Shag Rocks and the mainland of South Georgia was analyzed from ca 8700 stomachs collected in January/February 1985, […]
We present eddy-correlation measurements of heat and water vapour fluxes made during the Antarctic winter. The surface layer was stably stratified throughout the period of observation and sensible heat fluxes […]
