Rivers in the Northwest Territories draining the Canadian Shield in the zone of continuous permafrost have sulfate yields ranging from 3 to 6 meq m −2 yr −1 . Stable isotope ratios of sulfate sulfur from these rivers range from −0.91 to +7.01%. The negative value obtained for the Quoich River may indicate the presence of reduced sulfur compounds in its watershed. Results for the Tree. Ellice and Back Rivers may have been influenced by seasalt. Results for the other rivers are very similar to those obtained for surface waters at lower latitudes (47°N), indicating that the processes affecting the isotopic ratios of sulfate sulfur in surface waters operate similarly at 65°N and at 47°N.
