Tectonomagmatic controls on Gondwana break-up models: Evidence from the Proto-Pacific Margin of Antarctica
Read more of: Tectonomagmatic controls on Gondwana break-up models: Evidence from the Proto-Pacific Margin of AntarcticaGeochemical and isotopic data are presented that suggest the existence of a large, Middle Jurassic subduction‐related magmatic province common to both the Antarctic Peninsula and southern South America. We argue […]

The use of tiltmeters to study the dynamics of Antarctic ice-shelf grounding lines
Read more of: The use of tiltmeters to study the dynamics of Antarctic ice-shelf grounding linesNew tiltmeter data are presented from Doake Ice Rumples on Ronne Ice Shelf, Antarctica. Five sites which showed a tidal ice-shelf flexure have been analysed using an elastic beam model […]

Magnetic storm effects on the mid-latitude plasmasphere
Read more of: Magnetic storm effects on the mid-latitude plasmasphereWhistler mode group delays observed at Faraday, Antarctica (65°S, 64°W) decrease after the onset of magnetic storms, and slowly recover to normal levels in 1 or 2 days. This is […]
