Visualising the Aurora: Embodied and Instrumental Sensing throughout the International Polar and Geophysical Years (1880-1960)
… and understood during the International Polar and Geophysical Years of 1882-1883, 1932-1933 and 1957-1958. I explore the depiction of the phenomenon, from hand-drawings to radio echoes, while paying heed to what was occluded from portrayals, the imaginative and aesthetic considerations …

A multi-scaled approach to vegetation and landscape assessment in the Barents region: Reindeer habitat in a climate of change
The circumpolar Arctic is predicted to be particularly affected by global change, including climate change. Likely ecological vulnerabilities include flora and dependent fauna. Reindeer (Rangifer tarandus), a keystone Arctic herbivore, are of particular importance, ecologically, as well as …
