This data release is in partial fulfillment of an agreement between the U.S. Geological Survey and the University of California, Merced, related to a study funded through the California Department of Fish and Wildlife (PROPOSAL #: P1896056-01, TITLE: High Resolution Temporal and Spatial Mapping of Mercury in Surface Waters of the San Francisco Bay Delta), as part of the California Proposition 1 Water Quality, Supply, and Infrastructure Improvement Act of 2014. The overarching goal of this study was to develop models that can estimate surface-water concentrations of four mercury species (particulate and filter-passing fractions of total mercury and methylmercury) using a trio of high-resolution water-quality data collection platforms. Turbidity and fDOM are associated with total mercury and methylmercury species concentrations in SSJRD surface waters and are the two primary optical proxies for modeling mercury species from data derived exclusively via the remote sensing (satellite) platform. The purpose of the information contained on this Child Page is to document the development of remote sensing products (as GeoTIFF files) for turbidity and fDOM throughout the SSJRD.
