Trade Codes Related to the Lithium-Ion Battery Supply Chain for the United States, the European Union, and the People's Republic of China (2020-2021) Trade Codes Related to the Lithium-Ion Battery Supply Chain for the United States, the European Union, and the People's Republic of China (2020-2021)
This dataset presents information concerning 8- and 10-digit trade codes related to the rechargeable lithium-ion battery (LIB) supply chain for the People's Republic of China (PRC) and the European Union, and the United States as classified by Customs and Border Protection (CBP) rulings. Note that this dataset is not intended to be a complete or comprehensive list of trade codes for the...
Phytoplankton Community Composition and Abundance in Lake Okeechobee and the Okeechobee Waterway, Florida, USA, July and August 2019 Phytoplankton Community Composition and Abundance in Lake Okeechobee and the Okeechobee Waterway, Florida, USA, July and August 2019
This data release contains phytoplankton classification and enumeration results from two moving boat surveys conducted on July 15 - 18, 2019 and August 19 - 22, 2019. These data were collected from the Caloosahatchee River and estuary, the St. Lucie River and estuary, and Lake Okeechobee with funding provided by the USGS Priority Ecosystems Greater Everglades Program.
Isotopic ratios and element concentrations of U-Pb and Sm-Nd for scheelite petrochronology Isotopic ratios and element concentrations of U-Pb and Sm-Nd for scheelite petrochronology
Instrument, standard, and sample data from application of in situ laser ablation-inductively coupled plasma-mass spectrometry (LA-ICPMS) dating of scheelite in thin section, and sample data from isotope dilution thermal ionization mass spectrometry (ID-TIMS) scheelite dating are in this data release. Fractionation factor and ratio data in between NIST glass and natural scheelite as well...
Elemental Concentrations and Carbon and Oxygen Isotope Ratios in Mammillary Calcite from Devils Hole and Devils Hole II, Nevada, USA Elemental Concentrations and Carbon and Oxygen Isotope Ratios in Mammillary Calcite from Devils Hole and Devils Hole II, Nevada, USA
Elemental concentrations and stable oxygen and carbon isotope ratios are reported for five mammillary calcite specimens collected from the groundwater-filled fissures Devils Hole and Devils Hole II in the southern Amargosa Desert, south-western Nevada. Previous studies of these specimens yielded oxygen and carbon isotope chronologies of paleoclimatic and paleo hydrologic conditions over...
Surface-Water-Quality Data and Time-Series Plots to Support Implementation of Site-Dependent Aluminum Criteria in Massachusetts, 2018-19 (ver. 1.1, February 2023) Surface-Water-Quality Data and Time-Series Plots to Support Implementation of Site-Dependent Aluminum Criteria in Massachusetts, 2018-19 (ver. 1.1, February 2023)
This data release includes water-quality data collected at 38 sites in central and eastern Massachusetts from April 2018 through May 2019 by the U.S. Geological Survey to support the implementation of site-dependent aluminum criteria for Massachusetts waters. Samples of effluent and receiving surface waters were collected monthly at four wastewater-treatment facilities (WWTFs) and seven...
Projected future habitat, elevation change, and carbon accumulation of coastal wetlands in the Nisqually River Delta, Washington Projected future habitat, elevation change, and carbon accumulation of coastal wetlands in the Nisqually River Delta, Washington
This dataset consists of raster geotiff outputs from modeling habitat change, marsh vertical accretion, and carbon accumulation in the Nisqually River Delta, Washington, USA. These rasters represent projections of future habitat type, change in surface elevation above Mean Sea Level, and total sediment carbon accumulation since 2011 in coastal wetland habitats. Projections were generated...
