The chances of seeing icebergs in a particular area depend on the number of bergs, wind direction, oceans current and temperatures, and the amount of sea ice, or pack ice. John's, but these numbers can vary greatly from year to year. Only about 400-800 make it as far south as St. How many icebergs are there?Įvery year about 40,000 medium- to large-sized icebergs break off, or calve, from Greenland glaciers. Would you believe most are 10,000 years old? It’s true. Their sheer size will amaze you, and that's without seeing the ninety-percent still below the surface of the ocean. Roughly 90% of icebergs seen off Newfoundland and Labrador come from the glaciers of western Greenland, while the rest come from glaciers in Canada's Arctic. Once they head south, they rarely last more than one year. After slipping into the ocean, the bergs float in frosty arctic bays melting slowly, if at all, until passing through the Davis Strait and into the Labrador Current which carries them south into Iceberg Alley. The glaciers of western Greenland flow at speeds of up to seven kilometres a year, among the fastest moving in the world. Glaciers then "flow" or "creep" towards the ocean under their own weight, and eventually slip in. Each layer of snow compresses those below until, 60 to 70 metres down, glacial ice forms. Glaciers form on land by snow building up over thousands of years. Icebergs are edges of glaciers that have broken off and slipped into the ocean. What are icebergs and where do they come from?
