This data release provides quantitative whole rock geochemical results from The Geysers vapor-dominated geothermal field in California. The concentrations of major elements are reported in oxide weight percent by wavelength dispersive x-ray fluorescence (WDXRF), the concentrations for sixty elements are reported in elemental weight percent (pct) or parts per million (ppm) from inductively coupled plasma-optical emission spectrometry-mass spectrometry ICP-OES-MS analysis, mercury is reported in ppm by cold vapor atomic absorption spectrometry (CVAAS), and ammonium in ppm from automated colorimetry analysis. The analyses show significant enrichment of volatile elements and elements such as sulfur, boron, arsenic,...

This data release provides semiquantitative mineralogy results from X-ray diffraction (XRD) analyses of mineral scales from The Geysers vapor-dominated geothermal field in California. The mineral species and their abundances are reported in weight percent and values have been normalized to total 100 percent for each sample. The X-ray diffraction results show that the mineral samples from the wellheads are primarily composed of ammonium (NH4+) sulfate minerals and sassolite B(OH)3, whereas sulfide minerals such as cinnabar and pyrite are the most abundant minerals observed in the power plants. Mineral scales vary along the steam flow path, from the wellhead to power plants. Relatively abundant iron oxide and iron...

Climate adaptation planning provides a framework for Tribes to exercise sovereignty over wild resources important for the subsistence way of life and economic and cultural activities that are being impacted by climate change. The climate adaptation planning process includes identifying key resources that are currently being impacted by climate change, or that may be impacted in the future, as well as identifying practical and strategic steps that can be taken to mitigate or adapt to the changing circumstances. Through a partnership among the Ketchikan Indian Community, the Metlakatla Indian Community, OceansAlaska, and the University of Alaska Fairbanks this project will support Tribal- and Alaska Native-led...

This GeoPackage contains the analysis strata (“YKD_AnalysisStrata”) used in calculating population indices for ducks, loons, mergansers, grebes, gulls, and terns. This layer was created from the file (“YKD_DesignStrata”) when the existing rotating panel design was developed in 1999. This layer was originally created as an ArcInfo coverage, saved to a shapefile, and imported to SQLite Database format.

This is an SQLite GeoPackage simple feature multilinestring vector database of the Arctic Coastal Plain survey transects in coordinate reference system EPSG:4326. There is one layer for each year 2007 to 2023, although in general the there is a four panel rotation that varies each year. All years are provided because implementation of the panel design varied through time. The field”Year” given the calendar year that the transects were implemented, “Stratum” gives the strata name, “Transect” gives the transect identifier, and the “geom” field gives the simple feature Well Known Text geometry data. Note that these transect are the idealized design and are not an exact record of the true flight path or survey effort....

Provided here is a globally distributed catalog of earthquakes and nuclear explosions with calibrated hypocenters, referred to as the Global Catalog of Calibrated Earthquake Locations or GCCEL. This dataset contains more than 23,908earthquakes in 346 well distributed clusters. Currently there are more than 4M arrival times with the majority being the Pg, Pn, P, Sg, Sn and S phases. The term “calibrated” refers to the property that the hypocenters are minimally biased by unknown Earth structure and that the uncertainties are meaningful. Uncertainties are calculated using empirically determined variability of the arrival time data itself, specific to each calibrated cluster of hypocenters. The data are carefully processed...
