AbstractThe typical retreat of the sea ice cover from the late winter to late summer is shown on this map. Sea ice is any form of ice that is found at sea and has originated from the freezing of seawater. Melting of sea ice begins in spring in the Gulf of St. Lawrence and East Newfoundland, retreating northward towards the Labrador coast. In June openings appear in Baffin Bay and the Beaufort Sea, while clearing is already underway in Hudson Bay. Break-up continues throughout the summer months, reaching a minimum extent around mid-September. The map shows the typical retreat of the sea ice cover from late winter (mid-March) to late summer (mid-September) on a bi-weekly basis. The dates shown in the legend of the map indicate the extent of the sea ice cover at those dates.
Summary(Plain Language Summary, not published)
The map was originally published online in the Atlas of Canada, 6th Edition as an interactive digital map derived from a shapefile and mapped online using MapServer, a platform for publishing spatial data to the web. In order to preserve the geographical content of this Edition during its publication from 1999 to 2009 all the maps have been converted from their online interactive form to a raster and made available in PDF and JPEG.
