Plasmaspheric storm time erosion
Read more of: Plasmaspheric storm time erosionUnusually low whistler mode group delay times are observed by VLF Doppler receivers at both Faraday, Antarctica, and Dunedin, New Zealand, following magnetic storms. These are typically caused by plasmaspheric […]

The state and future of Mars polar science and exploration
Read more of: The state and future of Mars polar science and explorationAs the planet’s principal cold traps, the martian polar regions have accumulated extensive mantles of ice and dust that cover individual areas of ∼106 km2 and total as much as […]

Spatial patterns of diversity in the sea: bryozoan species richness in the North Atlantic
Read more of: Spatial patterns of diversity in the sea: bryozoan species richness in the North Atlantic1. We have examined large-scale geographical patterns in species richness for continental shelf bryozoan assemblages in the North Atlantic. Bryozoans are common and often abundant benthic organisms, but they have […]

High-time resolution conjugate SuperDARN radar observations of the dayside convection response to changes in IMF By
Read more of: High-time resolution conjugate SuperDARN radar observations of the dayside convection response to changes in IMF ByWe present data from conjugate SuperDARN radars describing the high-latitude ionosphere’s response to changes in the direction of IMF By during a period of steady IMF Bz southward and Bx […]

Poleward‐moving HF radar flow bursts in the cusp: Transient changes in flow speed or direction?
Read more of: Poleward‐moving HF radar flow bursts in the cusp: Transient changes in flow speed or direction?Poleward‐moving line‐of‐sight velocity “flow bursts” have been observed in the cusp by two southern hemisphere SuperDARN HF radars with overlapping fields‐of‐view. This has allowed the estimation of unambiguous two‐dimensional velocity […]

A new macroflora from the South Orkney Islands, Antarctica: evidence of an Early to Middle Jurassic age for the Powell Island Conglomerate
Read more of: A new macroflora from the South Orkney Islands, Antarctica: evidence of an Early to Middle Jurassic age for the Powell Island ConglomerateA macroflora from John Peaks, Powell Island, contains Sagenopteris nilssoniana, Cladophlebis oblonga, Brachyphyllum sp., Elatocladus confertus, and Sphenopteris sp. The macroflora is best correlated with the Botany Bay Group flora, […]
