Nunavut archaeological sites threatened by climate change may be saved thanks to new high-tech equipment, says the territory's director of culture and heritage.

Doug Stenton said new 3D technology and a ground-penetrating radar system can be used to quickly map the surface and sub-surface, and could be used to deal with sites affected by coastal erosion and melting permafrost.

The University of Manitoba has received funding to buy the technology and plans to use it in the Arctic.

"It will help us identify areas that need special attention...and help us plan strategies to protect the site, [such as] stabilization methods," Stenton said....
