1. An Arctic and Antarctic perspective on recent climate change

   We contrast recent climatic and environmental changes and their causes in the Arctic and the Antarctic. There are continuing increases in surface temperatures, losses of sea ice and tundra, and […]

2. A new supercontinent self-destruct mechanism: evidence from the Late Triassic–Early Jurassic

   We present a new conceptual model where supercontinents, by focusing subduction on narrow areas of the 670 km mantle discontinuity, trigger superplume events and initiate their own fragmentation. This supercontinent-triggered […]

4. Mapping ionospheric backscatter measured by the SuperDARN HF radars – Part 2: Assessing SuperDARN virtual height models

   The Super Dual Auroral Radar Network (SuperDARN) network of HF coherent backscatter radars form a unique global diagnostic of large-scale ionospheric and magnetospheric dynamics in the northern and southern hemispheres. […]

5. Mapping ionospheric backscatter measured by the SuperDARN HF radars – Part 1: A new empirical virtual height model

   Accurately mapping the location of ionospheric backscatter targets (density irregularities) identified by the Super Dual Auroral Radar Network (SuperDARN) HF radars can be a major problem, particularly at far ranges […]

6. Antarctic climate change over the twenty first century

   Here we present a new assessment of Antarctic climate change over the 21st century based on data from the models that were developed as part of the Intergovernmental Panel on […]

7. The Tectonothermal evolution and provenance of the Tyrone Central Inlier, Ireland: Grampian imbrication of an outboard Laurentian microcontinent?

   The Tyrone Central Inlier is a metamorphic terrane of uncertain affinity situated outboard of the main Dalradian outcrop (south of the Fair Head–Clew Bay Line) and could represent sub-arc basement […]

8. Characterizing ice sheets during the Pliocene: evidence from data and models

   The Pliocene (c. 5.3 – 1.8 Myr BP) was the last epoch of geological time in which global temperatures were generally higher than modern. It is important if we are […]

9. Remote sensing of the spatial and temporal structure of magnetopause and magnetotail reconnection from the ionosphere

   Magnetic reconnection is the most significant process that results in the transport of magnetised plasma into, and out of, the Earth’s magnetosphere-ionosphere system. There is also compelling observational evidence that […]

10. Elevated UV-B radiation modifies the extractability of carbohydrates from leaf litter of Quercus robur

    We examined the influence of elevated UV-B radiation on the extractability of carbohydrates from leaf litter of Quercus robur. Saplings were exposed to a 30% elevation above the ambient level […]

11. Basal conditions beneath enhanced-flow tributaries of Slessor Glacier, East Antarctica

    Radio-echo sounding data are used to investigate bed roughness beneath the three enhanced-flow tributaries of Slessor Glacier, East Antarctica. Slow-moving inter-tributary areas are found to have rough beds, while the […]

12. Circumpolar connections between Antarctic krill (Euphausia superba Dana) populations: investigating the roles of ocean and sea ice transport

    Antarctic krill, Euphausia superba Dana, has a heterogeneous circumpolar distribution in the Southern Ocean. Krill have a close association with sea ice which provides access to a critical food source […]
