The mission of the CIS is to provide the most timely and accurate information possible about ice in Canada's navigable waters. In support of this, its two main objectives are to ensure the safety of Canadians, their property and their environment by warning them of hazardous ice conditions in navigable Canadian waters, and to provide present and future generations of Canadians with sufficient ...
The Laurentide ice sheet (LIS) was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glaciation epochs, from 2.58 million years ago to the present.
The formation of 3 to 4 km (1.9 to 2.5 mi) thick ice sheets equate to a global sea level drop of about 120 m (390 ft) The Quaternary glaciation , also known as the Pleistocene glaciation , is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma (million years ago) and is ongoing.
Off the charts “crazy” heat in the North Atlantic ocean and record-smashing Antarctic sea ice lows last year are far more severe than what Earth’s supposed to get with current warming levels.
An unusually warm winter in Canada this year has delayed the opening of a 400-kilometer (250-mile) ice road that is rebuilt every year as the main conduit for Rio Tinto, Burgundy Mines , and De ...
Map of Labrador Current. The Labrador Current is a cold current in the North Atlantic Ocean which flows from the Arctic Ocean south along the coast of Labrador and passes around Newfoundland, continuing south along the east coast of Canada near Nova Scotia. Near Nova Scotia, this cold water current meets the warm northward moving Gulf Stream.
Deglaciation is the transition from full glacial conditions during ice ages, to warm interglacials, characterized by global warming and sea level rise due to change in continental ice volume. [1] Thus, it refers to the retreat of a glacier , an ice sheet or frozen surface layer, and the resulting exposure of the Earth 's surface.
Greenland ice sheet as seen from space. An ice sheet is a body of ice which covers a land area of continental size - meaning that it exceeds 50,000 km 2. [4] The currently existing two ice sheets in Greenland and Antarctica have a much greater area than this minimum definition, measuring at 1.7 million km 2 and 14 million km 2, respectively.
