Short summary

We measured rare earth element concentrations in sediment of the Mackenzie River Delta during winter and fall to understand how seasons affect their mobility. Winter conditions showed nearly one hundred times more dissolved rare earth elements than fall, driven by organic matter that binds and mobilizes these elements under ice. Since spring floods may flush this winter buildup into the Arctic Ocean, changing ice cover patterns could alter how rivers deliver trace elements to coastal waters.
