摘要:

The article discusses the distribution of icebergs reported on the basis of visual observations and radar “sightings”; duringVladivostok'ssouthward and northward passages during her voyage to rescueMikhail Somovin July‐August 1985. A total of 828 icebergs were recorded on the southbound passage and 1090 during the northbound passage. In terms of latitude the distribution displays a sharp decrease in numbers of icebergs as one moves north from the coast of Antarctica. An interesting feature, on both passages, was a sharp decrease in sightings of icebergs between 69° and 70° S; this latitude corresponds to a major center of a cyclonic gyral located at about this latitude. The dominant shapes of the icebergs were pyramidal, tilted, or overturned, i.e., shapes indicative of disintegration.
