Abstract
Bomb-produced radioactive fall-out layers are evident in the firn at the top of the Devon Island ice cap and also lower down in a zone where accumulation is in the form of re-frozen melt-water. This allows 1963–1974 snow accumulation (positive balance) gradients for the same period to be determined on sub-polar ice caps in Canada.Keywords
