ARCTIC Exceptionally Large Icebergs and Ice Islands in Eastern Canadian Waters: A Review of Sightings from 1900 to Present
ABSTRACT. A review of post-1900 sightings of ice islands and exceptionally large icebergs in eastern Canadian waters between Baffin Bay and the Grand Banks demonstrates that current estimates of the maximum expected iceberg lengths are below many of the reported values. Analysis of these sightings r...
