High altitude cosmic radiation measurements near the north geomagnetic pole
During the summer of 1937, a scientific expedition to Baffin Bay, led by Mr J. M. Wordie (1937, 1938) in the specially chartered Norwegian sealer, Isbjørn , had as its principal object the measurement of cosmic radiation at great altitudes near the north geomagnetic pole in North-West Greenland.
