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.


Science at Work: Defining Canada’s Continental Shelf Program

Canada is party to an international agreement called the United Nations Convention on the Law of the Sea that recognizes that coastal states can obtain rights and jurisdiction over their continental shelf beyond 200 nautical miles. Natural Resources Canada, Fisheries and Oceans Canada and Global Affairs Canada, with the help of other federal departments and agencies, are working on Canada’s submission to the United Nations, as part of a review process to clearly define our country’s offshore boundaries.
