Global climate is critically sensitive to physical and biogeochemical dynamics in the subpolar Southern Ocean, since it is here that deep, carbon-rich layers of the world ocean outcrop and exchange […]
A procedure is described for the determination without preconcentration of Cd, Cu, Pb and Zn in Antarctic snow, based on differential pulse anodic stripping voltammetry at a rotating glassy carbon […]
The Voyager missions have revealed that jovian kilometric radiation (emanating from Jupiter’s magnetosphere) is beamed away from the zenomagnetic equator. Results from GEOS 1 show that terrestrial non-thermal continuum or […]
During palaeobotanical studies in the Antarctic Peninsula in February 1979, late Cretaceous or younger fossil angiosperm leaves were found within volcaniclastic rocks widely believed to be of late Jurassic age1. […]
Lobes of Xanthoria elegans are shown to be engulfed by more rapidly growing neighbouring lobes, thereafter ceasing to grow, and the rate of lobe engulfment increases with thallus age. Similarly, […]
The lakes of Signy Island (60° 43′S, 45° 38′W), South Orkney Islands, Antarctica, provide a unique laboratory for the study of many processes including natural eutrophication. Current relationships between the […]
