Median height distributions of electron concentration may be determined from ionograms by means of the composite ionogram technique of Wright, or by inserting tabulated parameters in the idealized model of […]
Most animal species reproduce sexually and fully parthenogenetic lineages are usually short lived in evolution. Still, parthenogenesis may be advantageous as it avoids the cost of sex and permits colonisation […]
Results of analysis of the diurnal variations of hmF2 for Argentine Islands (65°15’S, 64°16’W) and Halley Bay (75°30’S, 26°40’W) are presented. It is shown that, for summer months, the diurnal […]
A comparison has been mager between ice velocities that were measured by the radio-echo technique and by a survey method on the Devon Island ice cap, Arctic Canada (lat. 75° […]
An ice shelf is a floating ice sheet, attached to land where ice is grounded along the coastline. Nourished both by surface snow accumulation and by glaciers and ice sheets […]
