Groundwater quality in the North San Francisco Bay shallow aquifer, California Groundwater quality in the North San Francisco Bay shallow aquifer, California
Groundwater provides more than 40 percent of California’s drinking water. To protect this vital resource, the State of California created the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The Priority Basin Project of the GAMA Program provides a comprehensive assessment of the State’s groundwater quality and increases public access to groundwater-quality information. The...

Tidally driven export of dissolved organic carbon, total mercury, and methylmercury from a mangrove-dominated estuary Tidally driven export of dissolved organic carbon, total mercury, and methylmercury from a mangrove-dominated estuary
The flux of dissolved organic carbon (DOC) from mangrove swamps accounts for 10% of the global terrestrial flux of DOC to coastal oceans. Recent findings of high concentrations of mercury (Hg) and methylmercury (MeHg) in mangroves, in conjunction with the common co-occurrence of DOC and Hg species, have raised concerns that mercury fluxes may also be large. We used a novel approach to...

Methyl mercury dynamics in a tidal wetland quantified using in situ optical measurements Methyl mercury dynamics in a tidal wetland quantified using in situ optical measurements
We assessed monomethylmercury (MeHg) dynamics in a tidal wetland over three seasons using a novel method that employs a combination of in situ optical measurements as concentration proxies. MeHg concentrations measured over a single spring tide were extended to a concentration time series using in situ optical measurements. Tidal fluxes were calculated using modeled concentrations and bi

From deposition to erosion: Spatial and temporal variability of sediment sources, storage, and transport in a small agricultural watershed From deposition to erosion: Spatial and temporal variability of sediment sources, storage, and transport in a small agricultural watershed
The spatial and temporal variability of sediment sources, storage, and transport were investigated in a small agricultural watershed draining the Coast Ranges and Sacramento Valley in central California. Results of field, laboratory, and historical data analysis in the Willow Slough fluvial system document changes that transformed a transport-limited depositional system to an effective...
