The reconfiguration of both the receiver dipole array and the pulse set used by the National Oceanic and Atmospheric Administration (NOAA) HF radar enables all ambiguity in polarization to be […]
As a result of recent field work, a new lithostratigraphic group is defined on the west coast of James Ross Island, Antarctica. Characterised by comparatively coarse-grained sediments, the Gustav Group […]
VLF goniometers have been used to study the direction of plasma convection in the evening plasmasphere. The results suggest that sometimes even for L values greater than 4 the electric […]
Gonadal size and the circulating concentrations of two pituitary hormones (luteinizing hormone and prolactin) and three gonadal steroids (testosterone, progesterone and oestradiol‐17β) were measured in two closely related Diomedea albatrosses […]
The reproductive endocrinology of the Wandering Albatross Diomedea exulans was studied at South Georgia to investigate the potential endocrine correlates of biennial breeding and of the acquisition of sexual maturity. […]
Blood samples were collected from free-living incubating Diomedea albatross during single incubation shifts, both daily (wandering albatross D. exulans and every 2 days (grey-headed albatross D. chrysostoma and black-browed albatross […]
The dark respiration of field‐fresh thalli of Umbilicaria antarctica Frey et Lamb is reported for temperatures from −5.5 to 19°C, and water contents from saturation to dryness. Detailed analysis of […]
