Data from the chemical analysis of archived stream-sediment samples, Alaska

Elemental concentration data for more than 1700 archived stream-sediment samples collected in Alaska.

Info
Reanalysis of Selected Archived NURE-HSSR Sediment and Soil Samples from Arizona, California, Idaho, Montana, Nevada, New Mexico, and Utah (ver. 3.0, October 2018)

Reanalysis, using modern methods, of nearly 60,000 NURE-HSSR archived samples collected over parts of Arizona, California, Idaho, Montana, Nevada, New Mexico, and Utah.

Info
Reanalysis of Additional Selected Archived NURE-HSSR Sediment Samples from Idaho and Montana

Reanalysis of existing samples provides more precise and accurate geochemical data because newer methods can be used. Stable isotopes of lead were also included. Data are provided in Microsoft Access, CSV, and shapefile formats.

Reanalysis of Selected Archived NURE-HSSR Sediment and Soil Samples from Alaska

New analysis of existing samples from this area, to improve precision and accuracy and consistency of the measurements with those made on newly-collected samples. Data are provided in Microsoft Access, Microsoft Excel, CSV, and shapefile formats.

Info
Legacy Geochemical Data from Hardcopy Records of Selected Past U.S. Geological Survey Projects

Geochemical data from selected USGS projects from the 1960s-1980s that were previously not published as digital data. Includes geochemical analyses from 36,498 samples of various types using analytical methods and instruments that were current when those studies were carried out. Data are provided in Microsoft Access, shapefile, and CSV formats.
