Impact of permafrost degradation on the extreme increase of dissolved iron concentration in the Amur river during 1995–1997 ...
Abstract Primary production in the Sea of Okhotsk is largely supported by dissolved iron (dFe) transported by the Amur river, indicating the importance of dFe discharge from terrestrial environments. However, little is known about the mechanisms of dFe discharge into the Amur river, especially in te...
