Observations by the Dynamics Explorer 1 satellite provide validation of the theory that terrestrial myriametric radiation is produced by the linear conversion of electrostatic upper hybrid waves to electromagnetic radiation […]
Second only to auroral kilometric radiation as the Earth’s most prominent radio emission, magnetospheric nonthermal continuum radiation has been the subject of numerous observational and theoretical investigations. It has been […]
Narrow-band jovian kilometric radiation (nKOM) is distinguishable from broad-band jovian kilometric radiation (bKOM), both discovered by the Voyager spacecraft1–3, by its generally lower intensity, its more restricted range of centre […]
Antarctic fish of the family Channichthyidae (Icefishes) lack the respiratory pigments haemoglobin and myoglobin. The morphometrics and ultrastructure of the ventricular myocardium of a benthic icefish,Chaenocephalus aceratus has been compared […]
The distribution and fine structure of muscle-fibre types has been determined for the pelagic fingerling and demersal adult stages of the antarctic teleost Notothenia neglecta Nybelin, collected from Signy Island, […]
1. Oxygen consumption, mitochondrial content and enzyme activities were determined in identified muscle fibre types of the ‘haemoglobin-less’ icefish Chaenocephalus aceratus Lonnberg. 2. Small bundles (2–12) of fast and slow […]
The two sibling species of giant petrels Macronectes halli and M. giganteus are the dominant avian scavengers in the Southern Ocean ecosystem. They breed sympatrically at a number of sub-Antarctic […]
Two types of generating mechanisms have been proposed to explain the observations of weak electrostatic waves near the local upper hybrid frequency fuh. In this paper data from the wave […]
