Maps showing concentrations of particulate methylmercury

Maps showing concentrations of particulate methylmercury (pMeHg) based on 3-day mapping transects in the Delta during October 2019 and January 2020, using turbidity and turbidity and latitude as proxies, respectively. Red circles indicate fixed stations where continuous in-situ data are collected, and where total Hg and MeHg forms are sampled over tidal cycles.
