Conclusion-ish
• Mostly a sink of methylmercury definitely an overall sink of water
• Sometimes a sink of THg, seasonally• Particulate THg is dominant fraction
• We need to know mooooooore about mercury
QUESTIONS andTHANKS!
• Many thanks to the Mercury group, Julianna Manning, Dave Bosworth, and Carol DiGiorgio

Conclusion-ish
• Mostly a sink of methylmercury and organic carbon and definitely an overall sink of water
• Sometimes a sink of THg• Particulate THg is dominant fraction• Total Suspended Solids and THg (particulate mostly) were seasonal• DOC and filtered MeHg were not correlated, TSS and particulate THg
and MeHg were correlated• Concentrations between ebbs and floods were not significantly
