Geospatial database for the spectral characteristics and mapping of lithium-rich playas in the Western U.S. Basin and Range (ver. 2.0, March 2025) Geospatial database for the spectral characteristics and mapping of lithium-rich playas in the Western U.S. Basin and Range (ver. 2.0, March 2025)

The data included here were used to evaluate the prospectivity for lithium in brines of playas of the western part of the Basin and Range Physiographic Province of the United States. Prospectivity is derived from the mappable criteria used in the descriptive deposit model published by Bradley and others (2013) and focused mainly from the remote sensing point of view. The playas in the...

Mercury Concentrations and Methylation Rate Potentials in Lake Mendota, Wisconsin, USA: 2020-2021 Mercury Concentrations and Methylation Rate Potentials in Lake Mendota, Wisconsin, USA: 2020-2021

This dataset describes mercury (Hg) concentrations and methylation rate potentials that were measured in Lake Mendota, Wisconsin, US in 2020 and 2021. This work is a collaboration between the University of Wisconsin, University of California-Davis, and the U.S. Geological Survey. Samples were collected to examine the linkages between Hg methylation, biogeochemical conditions, and...

Active channel mapping for the mainstem Willamette River, Oregon, in 2009 and 2016 Active channel mapping for the mainstem Willamette River, Oregon, in 2009 and 2016

The active channel of the Willamette River in western Oregon is the portion of the floodplain that regularly conveys water and bed-material sediment (typically sand and gravel) on an annual basis (Wallick and others, 2013). The active channel comprises features such as gravel bars, side channels, main channel and alcoves that contribute to the overall diversity of aquatic and floodplain...

Human-modified ponded features mapped within the Willamette River floodplain, Oregon, in 2018 Human-modified ponded features mapped within the Willamette River floodplain, Oregon, in 2018

The floodplains of the Willamette River and its major tributaries in western Oregon comprise a diverse array of natural and human-modified features that collectively support a wide range of habitats used by native fish and other wildlife. Like other large alluvial rivers, the Willamette River floodplain has many water bodies disconnected from the main river channel throughout most of the...
