Dam impact/disturbance metrics for the conterminous United States, 1800 to 2018 Dam impact/disturbance metrics for the conterminous United States, 1800 to 2018
This metadata record describes two metrics that quantitatively measure the impact of reservoir storage on every flowline in the NHDPlus version 2 data suite (NHDPlusV2) for the conterminous United States. These metrics are computed for every 10 years from 1800 - 2015. The first metric (DamIndex_EROM.zip) estimates reservoir storage intensity in units of days based on reservoir storage in...
SUPERSEDED: Data Associated with Algal Toxin Testing of Seabirds from the Bering and Chukchi Seas, 2017 SUPERSEDED: Data Associated with Algal Toxin Testing of Seabirds from the Bering and Chukchi Seas, 2017
This data set is comprised of three tables with results of algal toxin screening for saxitoxin and domoic acid. We used enzyme-linked immunosorbent assay (ELISA) and high-performance liquid chromatography (HPLC) to screen seabirds in the Bering and Chukchi Seas, 2017.

U-Pb Isotopic Data and Ages of Zircon from the Manzano Mountains, New Mexico U-Pb Isotopic Data and Ages of Zircon from the Manzano Mountains, New Mexico
This data set contains tables containing uranium-lead (U-Pb) isotopic data and the crystallization age of zircon from a metamorphic rock from the Manzano Mountains, New Mexico, collected in 2005. The bulk sample was processed into concentrated mineral separates of zircon at the University of Texas at Austin and analyzed by U.S. Geological Survey (USGS) research scientists at the Stanford...
