Spectral UV measurements over Europe within the Second European Stratospheric Arctic and Midlatitude Experiment activities

1 January, 1997 by Peter Kirsch

In the frame of the Second European Stratospheric Arctic and Midlatitude Experiment an intensive program of spectral measurements of global solar UV radiation was organized at several European sites, extending…

The pteridophyte Ashicaulis livingstonensis(Osmundaceae) from the Upper Cretaceous of Williams Point, Livingston Island, Antarctica

1 January, 1997

The presence of Ashicaulis livingstonensis sp. nov. in the Upper Cretaceous Williams Point Beds of Livingston Island, Antarctica, represents an important new record of the Osmundaceae in the southern high…

Quasiperiodic ∼5–60 s fluctuations of VLF signals propagating in the Earth-ionosphere waveguide: a result of pulsating auroral particle precipitation?

1 January, 1997

Subionospheric very low frequency and low-frequency (VLF/LF) transmitter signals received at middle-latitude ground stations at nighttime were found to exhibit pulsating behavior with periods that were typically in the ∼5–60…

Measurements of calcium and phosphorus concentrations in the neonatal dentine of Weddell and crabeater seals using energy-dispersive x-ray analysis

1 January, 1997

Concentrations of calcium and phosphorus were measured in the neonatal dentine of 11 crabeater and 11 Weddell seal postcanine teeth with an energy-dispersive x-ray analyser. The extent of variation in…

Individual and population level dispersal of black-browed albatrosses Diomedea melanophris and grey-headed albatrosses D. chrysostoma in response to Antarctic krill

1 January, 1997

Two congeneric albatrosses, Black-browed Diomedea melanophris and Grey-headed Albatrosses D. chrysostoma that nest at South Georgia have diets that differ mainly with respect to the amount of Antarctic Krill Euphausia…

Taxonomic investigations of palynomorphs from the Byers group (Upper Jurassic‐Lower Cretaceous), Livingston and Snow islands, Antarctic Peninsula

1 January, 1997

Two new palynomorph taxa are described, and several existing taxa are discussed from the Upper Jurassic‐Lower Cretaceous Byers Group of Livingston and Snow islands, South Shetland Islands, Antarctic Peninsula. Oligosphaeridium…

Validation of the surface energy balance over the Antarctic ice sheets in the U.K. Meteorological Office Unified Climate Model

1 January, 1997 by John King

Surface radiation measurements and other climatological data were used to validate the representation of the surface energy balance over the East Antarctic Ice Sheet in the U.K. Meteorological Office Unified…

Precautionary measures for a new fishery on Martialia hyadesi (Cephalopoda, Ommastrephidae) in the Scotia Sea: an ecological approach

1 January, 1997 by Paul Rodhouse

In anticipation of the development of a new fishery for the ommastrephid squid Martialia hyadesi in the Scotia Sea, this paper presents a revision of annual consumption of the species…
