We describe an HF antenna design and implementation intended for ground penetrating radar applications in glaciology and hydrology. The HF antenna is based on modifications of a twin terminated folded […]
The effects of freezing and thawing on a cell wall-less mutant (CW15+) of Chlamydomonas reinhardii were investigated by monitoring enzyme release, cell viability, cell ultrastructure, and lipid composition. Cells suspended […]

Chorismus antarcticus (Pfeffer, 1887) is a small benthic hippolytid shrimp which breeds seasonally, producing a batch of large, lipid-rich eggs that are brooded over winter by the female, and hatch […]
Fluctuations of the fundamental and harmonic frequencies of the Schumann (earth-ionosphere cavity) resonances measured near Tromsø, Norway, on 28 March 1979 are examined on a timescale of ≲ 20 minutes. […]
Ionograms from South Georgia (54°S, 37°W; L = 1.9) are used to investigate the influence of magnetic and solar activity upon the occurrence of the nocturnal intermediate layer. The diurnal […]
