The Li isotope ratios of samples nearer to the coast appear to be similar to that of seawater (d7Li = +31 per mil). Have you considered marine aerosols as a possible source of Li in this system?
I cannot calculate the atmospheric inputs of Li because the samples were acidified when collected and couldn’t analyze them for anions. Other published literature use [Cl] to calculate the atmospheric input. However, I have sea salt deposition data at each catchment and plotted against d7Li. There was no correlation at all. The study conducted in the Mackenzie River Basin with a similar environmental setting compared to the Yukon River Basin, the highest atmospheric input to riverine Li, was less than 1%. Therefore, I would say the lithium isotopic values of ~+31 per mil are not derived from marine aerosol inputs but from other sources, possibly lithology of the rivers draining in.

Dear Myunghak, congrats ! very nice job. Is this work already published ? Best regards Romain Millot
I read your paper on the Mackenzie Basin so many times!! Thank you. I'm writing my thesis now, my supervisor and I plan to publish it afterwards.
