2. Cretaceous-Tertiary high-latitude palaeoenvironments, James Ross Basin, Antarctica: Introduction

   The James Ross Basin, at the northern tip of the Antarctic Peninsula, provides the thickest and best-exposed onshore Cretaceous and Early Tertiary sedimentary succession in Antarctica. When compared with other […]

6. Temporal variability of the descent of high-alitutude NOx inferred from ionospheric data

   In this study we investigate periods of enhanced ionization in the mesosphere during Northern Hemisphere wintertime. Long-lasting ionization enhancements (days) are typically produced by solar proton events or by the […]

7. An alternative explanation of PMSE-like scatter in MF radar data

   There have been reports in the literature that spaced-antenna MF radars may provide a source of data on Polar Mesospheric Summer Echoes (PMSE). Even though the expected scatter from PMSE […]

8. Radiation belt electron precipitation fluxes associated with lightning

   In this study we consider the dependence of precipitation fluxes arising from whistler-induced radiation belt losses on the strength of the associated lightning’s return stroke current. As a result of […]

9. Coniacian ammonites from James Ross Island, Antarctica

   The Cenomanian-Santonian biostratigraphy of the James Ross Basin, north-eastern Antarctic Peninsula is in need of comprehensive revision. This is being achieved by the systematic re-investigation of a series of key […]

10. A new aspidostomatid bryozoan from the Cape Melville Formation (Lower Miocene) of King George Island, West Antarctica

    Fragments of large, bilamellar aspidostomatid bryozoan colonies occur in Early Miocene glaciomarine sedimentary sequences of the Cape Melville Formation, King George Island, South Shetland Islands, West Antarctica. Investigation of the […]

11. Evolution and diversity of the benthic fauna of the Southern Ocean continental shelf

    The modern benthic fauna of the Antarctic continental shelf is characterized by the lack of active, skeleton-breaking (durophagous) predators such as crabs, lobsters and many fish, and the dominance in […]

12. Maastrichtian stratigraphy of Antarctica

    Application of a strontium isotope stratigaphy to the Late Cretaceous sedimentary succession of Antarctica has provided the impetus for a comprehensive strati-graphical revision of the terminal Maastrichtian Stage. Both the […]
