1. Onset and development of the Drake Passage and Scotia Sea gateways and its influence on global ocean circulation and climate (IODP proposal)

   The DRAKE-SCOTIA SEA GATEWAYS is a new multidisciplinary International Ocean Discovery Program (IODP) drilling proposal aimed at determining the time of opening and pattern of development of gateways in the […]

2. Quiet daytime Arctic ionospheric D region

   Phase and amplitude measurements of VLF radio waves propagating sub‐ionospherically on long paths across the Arctic are used to determine the high latitude, daytime D region height and sharpness of […]

3. An updated model providing long-term data sets of energetic electron precipitation, including zonal dependence

   In this study 30‐ to 1,000‐keV energetic electron precipitation (EEP) data from low Earth orbiting National Oceanic and Atmospheric Administration and MetOp Polar Orbiting Environmental Satellites were processed in two […]

9. Geomagnetic modification of the mid-latitude ionosphere: Toward a strategy for the improved forecasting of ƒ0F2

   The 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 […]

10. Diffusion and location of hydrochloric acid in ice: Implications for polar stratospheric clouds and ozone depletion

    We 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 […]

11. Aggression, incubation behaviour and egg-loss in macaroni penguins, Eudyptes chrysolophus, at South Georgia

    In 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 […]
