The hydrology of subarctic northern watersheds is
changing in response to recent anthropogenic global warming [Hinzman et al., 2005]. Climate model results predict
the intensification of the hydrological cycle and increased
river discharge in subarctic and arctic regions [Milly et al.,
2005]. Increasing annual flows to the Arctic Ocean have
been detected in Eurasian rivers [Peterson et al., 2002;
McClelland et al., 2006]. However, decreasing annual flows
to the Arctic Ocean have been shown for rivers discharging
into Hudson, James and Ungava Bays [De´ry et al., 2005];
and basically unchanged annual flow to the Arctic Ocean
shown for northern Canadian rivers [De´ry and Wood, 2005].
