Geochemical data including mercury for subsamples of deep cores from the Cache Creek Settling Basin, Yolo County, California Sediment cores were collected in the Cache Creek Settling Basin (CCSB), Yolo County, California, during October 2011 at 10 locations (borehole sites) and during August 2012 at 5 other locations. Total core depths ranged from approximately 4.6 to 13.7 meters (15 to 45 feet), with penetration to about 9.1 meters (30 feet) at most locations. Detailed subsampling (3-centimeter intervals) was done at total of seven locations: six along an east-west transect in the southern part of the Cache Creek Settling Basin and at one in the northern part of the basin for analyses of total mercury; organic content; and cesium-137, which was used for dating. This data release reports results of the analyses of each subsample of these...

Clear Lake is popular for recreation and provides critical habitat to a wide variety of fish and bird species. Water quality in Clear Lake is degraded by both by mercury contamination and harmful algal blooms (HABs). The mercury contamination is largely associated with the Sulfur Bank Mercury Mine (SBMM), located on the eastern shore of the Oaks Arm in the northeastern portion of the Lake. The mine was operated intermittently from the 1870s until 1957 and is now a U.S. Environmental Protection...

In wells where adjacent formation tops are missing, no TVT value is calculated. The TVT values are a measure of vertical thickness and do not account for the structural dip of units encountered in the wellbore. In total, the dataset contains 115,789 TVT values calculated in 16,200 wells from the Williston Basin of North Dakota, South Dakota, and Montana.
