F-layer ionisation troughs are frequently observed in the sub-auroral and high-latitude ionospheres. We define the mid-latitude trough as the region of low plasma concentration at F-region altitudes that occurs near […]
A mathematical model of the ionosphere and plasmasphere that includes an eccentric dipole geomagnetic field has been constructed to model, in the first instance, whistler results at L = 2.5. […]
Measurements on krill from distinct swarms and echo-sounder measurements of the same swarms have been analysed using multivariate methods. The analysis has addressed the problems of whether krill swarms in […]
A technique, using Nuclepore polycarbonate membrane filters as a containing medium for very small volumes of ionic standard solutions, to produce homogeneous ice standards is described. The standards are suitable […]
The study of the “polar low episode” over the northern parts of the Norwegian Sea and the Barents Sea from 12 December 1982 to 16 December 1982 is continued. The […]
The transcurrent Gastre Fault System in central Patagonia, which is closely associated with subvolcanic granite emplacement, is recognized as a major dextral shear-zone and geological boundary. We propose its equivalence […]
The morphology of the respiratory system of the femaleVarroa jacobsoni (Oudemans, 1904) is described. The mobile, appendage-like, emergent peritreme may be ‘raised’ to lie against the ventral integument or ‘lowered’ […]
