Exploring for Minerals by Following the Path of Glaciers

Research scientist Roger Paulen and his colleagues are “Ore Detectives”! By studying how glaciers impacted the land surface of Canada, they provide framework information to help industry locate buried mineral deposits. Find out how they use mapping and sampling of the surficial sediments to increase exploration success in northern Canada.

Why are researchers interested in an earthquake that occurred over 300 years ago?

Hint: it’s the largest earthquake that ever hit eastern North America. So why the interest? It’s quite simple. By collecting and dating samples of wood and organic material buried in the debris of ground movements, the researchers can determine whether there have been other major quakes and thus measure the threat of earthquakes in the area.

Working the Line: Maintaining the border in Canada’s wilderness (photo gallery)

As a surveyor for the International Boundary Commission, Joe Harrietha “works the line” in locating and maintaining the vast Canada–United States border. The Canadian section of the Commission is part of Natural Resources Canada, and he’s worked in some of the most remote and scenic areas in Canada for more than 25 years. These photos are from some of his expeditions.

A global information highway to meet the challenges of a fragile Arctic ecosystem

OTTAWA - Climate change affects the Arctic in different ways. Regional impacts include coastal erosion, evolving ocean currents and temperatures, shifting migration patterns over land and sea, and melting permafrost that heaves buildings and roads.

Learning from Tragedy – The 1929 Tsunami (Ask NRCan)

Marine geoscientist Calvin Campbell joins us to talk about the importance of a specific underwater landslide that caused a massive tsunami in Newfoundland back in 1929. Calvin is part of a team studying this historical landslide, and shares with us recent findings that changed our perception of the event.
