回顾1900年后在加拿大东部巴芬湾和大浅滩之间水域发现的冰岛和特大型冰山，表明目前对冰山最大预期长度的估计低于许多报告的值。对这些目击事件的分析表明，在本世纪上半叶，北纬55度以南地区的目击事件频率和报告的最大长度比1950-90年期间要多。然而，1991年的最近目击表明，在为大浅滩或拉布拉多大陆架设计固定近海结构时，仍应考虑特大型冰山。关键词：冰山、冰岛、拉布拉多海、大浅滩、近海石油
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 reveals that for the area south of 55 N the frequency of sightings and the maximum reported lengths were greater during the first half of this century than during the period 1950-90. However, recent sightings in 1991 demonstrate that exceptionally large icebergs should still be considered when designing fixed offshore structures for the Grand Banks or Labrador Shelf.
