The effectiveness of the Rectangular Midwater Trawl (RMT) for sampling krill swarms was studied by observing the behaviour of swarms in the vicinity of the net using echosounders. Large scale […]
Immediate-energy-supply pathways were analysed during burst-swimming in white muscle of the Antarctic fish Notothenia neglecta, (collected during Austral summer 1984 near Signy Island, South Orkneys). Selected enzyme activities were determined, […]
The availability of representative empirical models of the variation of the electron concentration with height in the ionosphere is one critical element in the development of practical schemes for providing […]
A simple user interactive technique that allows digital ionosonde sky map echo location data to be dealiased uniquely is described. Unambiguous tracking of large‐scale ionospheric features is thus made possible. […]
Rates of disappearance of dead material of Polytrichum alpestre and Chorisodontium aciphyllum from a moss turf community and of Drepanocladus uncinatus, Calliergon sarmentosum and Cephaloziella varians from a moss carpet […]
Bipolar bivalve genera probably existed through the greater part of late Mesozoic (i.e. late Jurassic–late Cretaceous) time. Of the various theories put forward to account for their presence, those based […]
Since 1981, the British Antarctic Survey has flown 27 000 line kilometres over Ronne Ice Shelf, during which radio-echo ice thicknesses were recorded. An earlier map of ice thickness was […]
