The cold saline springs at Gypsum Hill (GH) and Colour Peak (CP) in the Canadian high Arctic are rare examples of perennial flows in thick continuous permafrost. We surveyed the microbial diversity of the springs by analyzing clone libraries of the small subunit rRNA gene. Half of the bacterial clon...
