1. On the association between northward turnings of the interplanetary magnetic field and substorm onsets

   We re-examine whether substorms are triggered by solar wind fluctuations or an internal magnetospheric instability by comparing the statistical associations between substorm onsets and (1) an external trigger definition, (2) […]

2. A climatology of tides and gravity wave variance in the MLT above Rothera, Antarctica obtained by MF radar

   A cumulative total of over 5 years of data from an MF radar situated at Rothera (67°S, 68°W) on the Antarctic Peninsula have been used to derive climatologies of periodic […]

3. Predator–prey interactions: why do larger albatrosses eat bigger squid?

   The relationship between predator sizes and prey sizes is well documented for terrestrial but rarely for marine ecosystems. We show that wandering albatrosses, the biggest albatross species, feed on larger […]

4. Why is it hard to predict the future of ice sheets?

   Ice sheet retreat, hypotheses of instability could be missing important processes that limit the rate or extent of retreat, or conversely, Ice sheet behavior is strongly influenced by processes at […]

5. 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 […]

6. 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 […]

8. 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. […]

9. 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 […]

10. 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 […]

11. 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 […]

12. 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 […]
