Ray tracing of electrostatic waves in a hot plasma and its application to the generation of terrestrial myriametric radiation
Read more of: Ray tracing of electrostatic waves in a hot plasma and its application to the generation of terrestrial myriametric radiationThe first results from the program HOTRAY for ray tracing electrostatic and electromagnetic waves in a hot plasma are presented. The calculations are applied to the linear mode‐conversion window theory […]

The margins of the South Orkney microcontinent
Read more of: The margins of the South Orkney microcontinentMarine geophysical studies of the South Orkney microcontinent show two intersecting tectonic fabrics of different age. The older fabric is oriented E-W, and represents the magmatic arc and fore-arc created […]

Post-subduction alkaline volcanism along the Antarctic Peninsula
Read more of: Post-subduction alkaline volcanism along the Antarctic PeninsulaFollowing the cessation of subduction along the Antarctic Peninsula, there was a change in the character of the magmatism from calc-alkaline to alkaline. A Miocene-Pliocene suite of basanites, tephrites and […]

Confusion of place names; an example from Antarctica
Read more of: Confusion of place names; an example from AntarcticaPlace names in the Hughes Bay area, Danco Coast, Antarctica well illustrate naming problems that give rise to confusion or ambiguity. This note shows the origins of conflicting place names, […]

Interconnectivity between volume transports through Arctic straits
Read more of: Interconnectivity between volume transports through Arctic straitsArctic heat and freshwater budgets are highly sensitive to volume transports through the Arctic‐Subarctic straits. Here we study the interconnectivity of volume transports through Arctic straits in three models; two […]

The climate of the Antarctic Peninsula during the 20th century- evidence from ice cores
Read more of: The climate of the Antarctic Peninsula during the 20th century- evidence from ice coresThe Antarctic Peninsula (AP) is a region of special climatological interest. The late twentieth century has been a period of warming surface temperatures, enhanced mass loss from melting glaciers and […]

Interhemispheric survey of polar cap aurora
Read more of: Interhemispheric survey of polar cap auroraThis study investigates the interhemispheric nature of polar cap auroras via ultraviolet imaging, combined with particle data, to determine whether they occur on open or closed field lines. Data from […]
