Mineralogic, grain-size, biologic, and stable isotopic analyses of core TOPGUN-SODA10 2A-K from Big Soda Lake, Nevada, USA 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...

Water and surficial sediment samples were collected once at 9 locations. A sediment core (33 cm long) was extracted from Las Vegas Bay to assess changes in microplastic deposition over time. Striped bass (Morone saxatilis), common carp (Cyprinus carpio), quagga mussels (Dreissena bugensis), and Asian clams (Corbicula fluminea) were sampled at a subset of locations to assess biological uptake of microplastics. Sampling and analysis methods are described in the Processing Steps section of the metadata. All samples were...

To investigate whether environmental contaminant exposure is associated with alterations in male common carp (Cyprinus carpio) gamete quality and endocrine- and reproductive parameters, data were collected among sub-basins (n = 7) over 7 years (1999 to 2006). Endpoints included the sperm quality parameters of motility, viability, mitochondrial membrane potential, count, morphology, and DNA fragmentation; plasma components were vitellogenin (VTG),...

The data were collected for two separate projects: (1) determining the source of lithium in Bristol Dry Lake (BDL), and (2) determining the mechanism of sinter formation on Paoha Island, Mono Lake. The data from BDL were collected in collaboration with Standard Lithium Ltd. who drilled 6 new proprietary wells in 2017 and 2018 on the playa. The wells were not cored, but cuttings were available for sampling a few months after the drilling was completed. The wells were up to 1500 feet deep. Cuttings were kept in the dark in sealed plastic... Categories: Data; Tags: Bristol Dry Lake, California, Geochemistry, Mono Lake, Paoha Island, All tags...
