Extending our outer limits: Canada’s 2019 Arctic Ocean continental shelf submission to the United Nations

The Arctic Ocean is a vast, cold, isolated and utterly fascinating part of the northern hemisphere. Beneath its surface, thousands of metres below, is an extension of our country known as the continental shelf. And now, based on massive amounts of geoscientific data measuring the seafloor, an additional 1.2 million square kilometres could be added to Canada’s land area of 9.98 million km2.

Studying Permafrost in the Canadian Arctic (Byte-Sized Science)

Permafrost scientists Stephen Wolfe and Peter Morse travelled to the western Canadian arctic to observe permafrost conditions along the Inuvik to Tuktoyaktuk highway. The highway must be constantly maintained to ensure safe driving conditions over the permafrost. Stephen explains the type of geological studies he and Peter conducted to better understand permafrost conditions.

Measuring Lake Ice Thickness From Space (Byte-Sized Science)

Research scientist Joost Van der Sanden explains how his team is developing a method to map the thickness of lake ice cover from space by analyzing a combination of radar satellite imagery and fieldwork data. Information on lake ice thickness supports the operation of seasonal roads that facilitate valuable land transport to isolated Canadian sites (e.g., communities, mines) and can be used as an indicator of climate change.
