Geosciences Column: Perfecting Palaeogeographic Reconstructions

We model the changes in the geographic location of continents via paleogeographic reconstructions. However, the current methodology for generating these reconstructions is not without problems! Publication of palaeogeographic reconstructions is scarce, probably resulting from the difficulties associated with generating them. Conventional reconstructions are presented as static maps which have poor ...[Read More]

Imaggeo on Mondays: Wonderings and weathering

Leaving as soon as my diploma thesis (on epiphytic lichens) was written, we set off into the distance to work and travel. We chose New Zealand as our dream destination because these two islands have so many different landscapes to offer – and this is how I ...[Read More]

Nothing better characterises the wild US West than endless landscapes of red hoodoos, spires of rock protruding from the bottom of an arid drainage basin or badland. Found mainly in desert and dry, hot areas, hoodoos are distinctive from similarly-shaped formations, such as spires or pinnacles, because their profiles vary in thickness throughout their length. Their distinctive colour bands are the ...[Read More]

It is separated from Greenland only by the Nares Strait, a major pathway for sea ice flushing out of the High Arctic. Belonging to the Canadian territory of Nunavut, Ellesmere’s perman ...[Read More]
