Exploring about the North Pole of the Winds La navigation aérienne transatlantique

Abstract

(1) PROF. HOBBS'S book is a well-illustrated and entertainingly written account of three expeditions under his leadership between 1926 and 1929 to the south-west coast of Greenland. The expeditions were organised as a University of Michigan enterprise, and were for the purpose of studying the wind system controlled by the Greenland ice-sheet. An aerological station was established on Mt. Evans at a little above 1000 feet, some distance inland from Holstenborg in about latitude 67° N., and functioned uninterruptedly for two years. The staff of the observatory had to be changed at intervals, and though the latter has now been closed, everything has been left in readiness for a resumption of activity in the future. A large number of balloon ascents were made from here and at encampments elsewhere in this part of Greenland in addition to the usual ground observations, and several sledge journeys were conducted to the inland ice-sheet.
