An evaluation of differential pulse anodic stripping voltammetry at a rotating glassy carbon electrode for the determination of cadmium, copper, lead and zinc in antarctic snow samples
Read more of: An evaluation of differential pulse anodic stripping voltammetry at a rotating glassy carbon electrode for the determination of cadmium, copper, lead and zinc in antarctic snow samplesA 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 […]

Latitudinal beaming of planetary radio emissions
Read more of: Latitudinal beaming of planetary radio emissionsThe 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 […]

Lobe growth and marginal zonation in crustose lichens
Read more of: Lobe growth and marginal zonation in crustose lichensLobes 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, […]

Characteristics and classification of the lakes of Signy Island, South Orkney Islands, Antarctica
Read more of: Characteristics and classification of the lakes of Signy Island, South Orkney Islands, AntarcticaThe 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 […]
