Mackenzie River
At , the Mackenzie River drainage basin encompasses nearly 20 percent of Canada. About , or 54 percent of the basin, lies above Great Slave Lake. Permafrost underlies about three-quarters of the watershed, reaching up to deep in the Mackenzie Delta. As a whole, the Mackenzie basin receives only meager to moderate rainfall, averaging over the entire basin, though mountain areas experience much higher precipitation, and areas near and north of the Arctic Circle receive much lower precipitation.

Saanich Inlet, at the southern end of Vancouver Island, Canada, is a naturally hypoxic basin. A shallow sill (70 m) at the mouth isolates the deep basin (215 m) that experiences seasonal deep-water anoxia as a result of high primary productivity and subsequent degradation of sedimented organic matter. The Saanich Inlet network consists of cabled arrays of instruments in Mill Bay, Patricia Bay and an autonomous mooring at the entrance (sill) to the inlet. Two cabled surface buoys are connected to the Patricia Bay installation, supporting a technology testbed facility (Patricia Bay) and a full water column observation station (Coles Bay). Patricia Bay installations include:
