These data were collected from the TOPGUN-SODA10 2AK core collected in 2010 by LacCore (University of Minnesota), the USGS. and the University of California (U.C.) Berkeley. The 8.9 meter length core had stable isotopes of oxygen and carbon sampled every 10 millimeters or so, and diatoms samples at every 50 millimeters to 200 millimeters depending on the depth in the core. mineralogic data were collected using X-ray diffraction and grain-size analysis were done at various depths. These data are used to interpret the Holocene and late Pleistocene hydrology and paleoclimate of the lake and the region. The interpretation can be found in: Rosen, M.R., Reidy, L., Starratt, S., Zimmerman, S., in review, Middle Holocene...

Due to declining water levels and increasing salinity in the Salton Sea which may increase the hazards to wildlife, the U.S. Geological Survey and U.S. Bureau of Reclamation are re-evaluating selenium concentrations in the region. As part of this work, selenium concentrations in water and sediment samples and selected other inorganic constituents were compiled from published reports, public databases, and unpublished archives into a tabulated spreadsheet. This spreadsheet represents a rapid synthesis of available data on selenium concentrations in water and sediment in the region surrounding the Salton Sea, however it does not include all data ever published in the region. Additionally, the data compilation was...

A time series of nutrient and mean daily discharge data were used to create models of daily concentration and loads for selected streams of the Lake Tahoe watershed. A total of 15 sites have records ranging from as early as 1972 to 2017. Nutrients in the data set include nitrate, ammonium, Kjeldahl Nitrogen, orthophosphate, and total phosphorus. Total suspended sediment concentrations are also included. Discharge data are included as mean daily values in cubic meters per second. The data were used to produce daily and annual models of concentrations and loads and associated daily and annual loads of these constituents. Trends in these constituents were also calculated. The U.S. Geological Survey model, Weighted...
Water chemistry data from wells drilled by brine operations in Bristol and Cadiz Basins in San Bernardino County, California, USA. These data are used in the Journal article: Rosen, M.R., Stillings, L.L., Kane, T., Campbell-Hay, K., Vitale, M., Spanjers, R., 2020, Possible sources and mechanisms of anomalous Li and Ca enrichment in the Bristol Dry Lake brine compared to other playa brines in the Barstow-Bristol Trough, California, USA.
