1. The state and future of Mars polar science and exploration

   As 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 […]

2. Spatial patterns of diversity in the sea: bryozoan species richness in the North Atlantic

   1. 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 […]

5. High-time resolution conjugate SuperDARN radar observations of the dayside convection response to changes in IMF By

   We 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 […]

6. 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 […]

8. A composite gazetteer of Antarctica

   Publication of the Composite gazetteer of Antarctica by the SCAR Working Group on Geodesy and Geographic Information is a major milestone in the evolution of Antarctic toponymy. It has taken […]

9. A petrified cycad trunk from the Late Cretaceous of the Larsen Basin, Antarctica

   Cetricycas antarcticus gen. et sp. nov. occurs in the Late Coniacian to Campanian Lachman Crags Member of the Santa Marta Formation, Marambio Group, James Ross Island, Antarctica. The petrified trunk […]

10. A new macroflora from the South Orkney Islands, Antarctica: evidence of an Early to Middle Jurassic age for the Powell Island Conglomerate

    A 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, […]

12. Temporal plankton dynamics in an oligotrophic maritime Antarctic lake

    1 The population density, diversity and productivity of the microbial plankton in an oligotrophic maritime Antarctic lake were studied for a 15-month period between December 1994 and February 1996. 2 […]
