Data

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...

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...

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...

This data set collects, from peer-reviewed and openly available research, values of sea surface temperature (SST) that occurred at select sites across the Earth during a brief period of the lower- Zanclean. SST data reported here represent, for each site, an average of SSTs, derived from alkenone analysis. The data collected are centered on two time slices. The PRISM5.1 time slice at 4...

The USGS collected water level time series data sets using a submersible pressure transducer at FORGE WELL 58B-32 during an aquifer test from February 12 to February 16, 2024. Transmissivity of the pumped aquifer was estimated to be 37,520-55,080 square feet per day using a Theis solution for unconfined aquifers provided by AQTESOLV software. The hydraulic conductivity of the aquifer was...

This dataset represents the network-adjusted results of relative- and absolute-gravity surveys performed from 2020 to 2023 in and near the city of Phoenix, Arizona. Relative surveys were done using a Zero Length Spring, Inc. Burris relative-gravity meter. Absolute-gravity surveys were done using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. The effect of solid Earth tides and...
