Eurasian river spring flood observations support net Arctic Ocean mercury export to the atmosphere and Atlantic Ocean [Earth, Atmospheric, and Planetary Sciences]

Midlatitude anthropogenic mercury (Hg) emissions and discharge reach the Arctic Ocean (AO) by atmospheric and oceanic transport. Recent studies suggest that Arctic river Hg inputs have been a potentially overlooked source of Hg to the AO. Observations on Hg in Eurasian rivers, which represent 80% of freshwater inputs to the...
