It proved to be an excellent tool for the detection of both icebergs and sea ice, and provided 97 percent of the 1983 iceberg sightings. The iceberg population was greater than normal this year due, in part, to lower than normal temperatures recorded throughout Newfoundland and Labrador which hindered the melting process of the sea ice and extended its limits farther south. A combination of northerly winds in the Labrador Sea combined with generally southwesterly and westerly winds off the Newfoundland coast also hindered the breakup of the sea ice, which protected the icebergs, allowing them to drift farther south and in larger numbers.
