1. Exploring former subglacial Hodgson Lake, Antarctica Paper I: site description, geomorphology and limnology

   At retreating margins of the Antarctic Ice Sheet, there are a number of locations where former subglacial lakes are emerging from under the ice but remain perennially ice-covered. This paper […]

2. Mechanisms of Holocene palaeoenvironmental change in the Antarctic Peninsula region

   The Antarctic Peninsula is one of the three fastest warming regions on Earth. Here we review Holocene proxy records of marine and terrestrial palaeoclimate in the region, and discuss possible […]

3. Holocene relative sea-level change and deglaciation on Alexander Island, Antarctic Peninsula, from elevated lake deltas

   Field data constraining the rate and spatial pattern of deglaciation and relative sea-level (RSL) change on the Antarctic Peninsula (AP) are relatively sparse, but are needed to improve regional ice […]

4. Exploring former subglacial Hodgson Lake, Antarctica. Paper II: palaeolimnology

   Direct exploration of subglacial lakes buried deep under the Antarctic Ice Sheet has yet to be achieved. However, at retreating margins of the ice sheet, there are a number of […]

5. Systematic Metastable Atmospheric Regime Identification in a AGCM

   In this study the authors apply a recently developed clustering method for the systematic identification of metastable atmospheric regimes in high-dimensional datasets generated by atmospheric models. The novelty of this […]

6. Zircon U-Pb dating of Mesozoic volcanic and tectonic events in northwest Palmer Land and southwest Graham Land, Antarctica

   New whole rock Rb-Sr and zircon U-Pb geochronological data and Sm-Nd isotopic data are presented from the central magmatic arc domain of the Antarctic Peninsula in the area of northwest […]

7. Oithona similis in a high latitude ecosystem: abundance, distribution and temperature limitation of fecundity rates in a sac spawning copepod

   In this study we report the abundance, fecundity and an index of mortality of Oithona similis across a large latitudinal and temperature range within the Southern Ocean. The abundance of […]

8. Trends in the sources and sinks of carbon dioxide

   Efforts to control climate change require the stabilization of atmospheric CO2 concentrations. This can only be achieved through a drastic reduction of global CO2 emissions. Yet fossil fuel emissions increased […]

9. Palaeoproterozoic to Palaeozoic magmatic and metamorphic events in the Shackleton Range, East Antarctica: Constraints from zircon and monazite dating, and implications for the amalgamation of Gondwana

   A comprehensive set of new geochronological data from different parts of the Shackleton Range in East Antarctica, comprising U–Pb single zircon and Th–U–Pb single and multi-grain monazite data, combined with […]

10. Energetic electron precipitation from the outer radiation belt during geomagnetic storms

    Relativistic electron precipitation changes the chemistry of the upper atmosphere and depletes ozone, but the spatial and temporal distributions are poorly known. Here we survey more than 9 years of […]

11. FIRST ANTARCTIC CLIMATE EVOLUTION SYMPOSIUM Workshop on Amundsen Sea Embayment: Tectonic and Climatic Evolution Programme and Abstracts

    The Amundsen Sea Embayment is the most rapidly changing sector of the West Antarctic Ice Sheet and contains enough ice to raise global sea level by 1.2 m. Over the […]

12. Hidden Archaean and Palaeoproterozoic crust in NW Ireland? : evidence from zircon Hf isotopic data from granitoid intrusions

    The presence of major crystalline basement provinces at depth in NW Ireland is inferred from in situ Hf isotope analysis of zircons from granitoid rocks that cut structurally overlying metasedimentary […]
