Desert dune landscapes have fascinated and inspired writers and artists from Shelley's Ozymandias to Tatooine in the opening scenes of Star Wars. The reality is no less bizarre and wonderful. Desert dunes are uniquely dynamic landscapes which reveal further mysteries as fast as progress in science is made. The story takes us from the pioneering work of Brigadier Ralph Bagnold (who found time to research and write a seminal textbook whilst deep behind enemy lines in the Sahara during WWII), via Antarctica, chaos theory and climate change... to Saturn's icy moon Titan where methane rain sometimes falls on the giant equatorial dunes.

Dr Matt Telfer is a lecturer of Physical Geography at Plymouth University and his interests include desert geomorphology, environmental change and relaxing around the campfire amongst the dunes after a good day's fieldwork

Plymouth Scibar is brought to you by the Plymouth Branch of the British Science Association.
