Decreasing river discharge in northern Canada
[1] Freshwater discharge to high-latitude oceans in 64 Canadian rivers is investigated. The mean annual discharge rate attains 1252 km3 yr1 for an area of 5.6 106 km2, equating to a sink of 225 mm yr1 in the surface water budget of northern Canada (excluding the Arctic Archipelago where insufficient...
