Geomagnetic modification of the mid-latitude ionosphere: Toward a strategy for the improved forecasting of ƒ0F2
Read more of: Geomagnetic modification of the mid-latitude ionosphere: Toward a strategy for the improved forecasting of ƒ0F2The reduction of maximum usable frequency (MUF) during a geomagnetic storm represents a serious hindrance to the efficient operation of HF transmission links. This paper outlines a new approach to […]

Diffusion and location of hydrochloric acid in ice: Implications for polar stratospheric clouds and ozone depletion
Read more of: Diffusion and location of hydrochloric acid in ice: Implications for polar stratospheric clouds and ozone depletionWe have carried out experiments to study the incorporation and movement of HCl within the structure of ice. These involved freezing HCl solutions, and observing them in a scanning electron […]

Aggression, incubation behaviour and egg-loss in macaroni penguins, Eudyptes chrysolophus, at South Georgia
Read more of: Aggression, incubation behaviour and egg-loss in macaroni penguins, Eudyptes chrysolophus, at South GeorgiaIn crested penguins Eudyptes spp., the first-laid (A) egg is very much smaller than the second (B) egg and, although viable, rarely survives to hatching. I tested the recent hypothesis […]
