![]() Dissolved and particulate matter and chlorophyll-a (representing phytoplankton) correlate with optically active water-quality constituents. Data gathered from this combination of methods enables researchers to map surface-water total Hg and MeHg forms within the Delta at temporal and spatial resolution never before achievable.Ĭonceptual model of the proposed work. This project combines traditional field-based sampling and continuous fixed-station monitoring with high-speed boat traverses and satellite RS, focused on the Sacramento – San Joaquin Delta. Now, with the availability of new tools such as remote-sensing (RS) platforms, in-situ optical sensors, and flow-through systems deployed on high-speed watercraft, scientists have the opportunity to gain a better understanding of the spatial and temporal dynamics of Hg forms and their transport and fate in this complex aquatic system. However, there is widespread recognition of the need for more comprehensive monitoring of both Hg and MeHg than is practical with traditional field-sampling methods. The formation, fate, and transport of methylmercury (MeHg), a particularly toxic organic form of Hg that readily bioaccumulates in wildlife, has been studied extensively throughout the system. ![]() ![]() Mercury (Hg) is a contaminant of significant concern in the San Francisco Bay-Delta estuary and watershed (Bay-Delta).
