Summary

The goal of this study was to develop a suite of inter-related water quality monitoring approaches capable of modeling and estimating the spatial and temporal gradients of particulate and dissolved total mercury (THg) concentration, and particulate and dissolved methyl mercury (MeHg), concentration, in surface waters across the Sacramento / San Joaquin River Delta (SSJRD). This suite of monitoring approaches included: a) data collection at fixed continuous monitoring stations (CMS) outfitted with in-situ sensors, b) spatial mapping using boat-mounted flow-through sensors, and c) satellite-based remote sensing. The focus of this specific child page is to document the temporal high-resolution (15 minute) in-situ sensor data collected [...]

Purpose

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 THg and MeHg) using a trio of high-resolution water-quality data collection platforms. The data presented on this Child Page represents that associated with the continuous monitoring station, high temporal resolution (15-minute), data collection platform.
