The British Arctic Air Route Expedition (BAARE) of 1930-31 was a privately funded expedition to the east coast and interior of Greenland. The expedition, led by Gino Watkins, aimed to draw improved maps and charts of poorly understood sections of Greenland’s coastline, and to gather climate data from the coast and interior icecap during the north polar winter.
The official account is in F. Spencer Chapman’s Northern Lights.
The expedition is described in Jeremy Scott’s book Dancing on Ice: A Stirring Tale of Adventure, Risk and Reckless Folly
Further background and many photos from the expedition are available at on the Scott Polar Research Institute’s website: http://www.spri.cam.ac.uk/library/pictures/catalogue/baare/
There is material on the history and the team on http://www.icecapstation.com/ a site dedicated to an expedition by Chloe Courtauld, the great niece of one of the original team members – August Courtauld, to retrace the expeditions steps.
Gino Watkins by J.M. Scott is a biography of Gino Watkins, leader of the British Arctic Air Route Expedition.
