Impacts of bird predation on the detection of acoustic telemetry tags in fish Impacts of bird predation on the detection of acoustic telemetry tags in fish
Note: this data release has been superseded by version 2.0, available here: https://doi.org/10.5066/P14P7RT6. This data release contains the methodology and results of two field experiments performed in 2024 to better understand how predation impacts detection efficiency of acoustic tags. The first experiment was a static approach focusing on how different tag types, tag power, depth...
Repeat microgravity data from Rio Rancho, New Mexico, 2019-2023 Repeat microgravity data from Rio Rancho, New Mexico, 2019-2023
This dataset represents the network-adjusted results of relative- and absolute-gravity surveys performed from 2019 to 2023 in Rio Rancho and Bernalillo County, New Mexico. Relative surveys were conducted using a Zero Length Spring, Inc. Burris relative-gravity meter. Absolute-gravity surveys were conducted using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. The effect of solid...
Geospatial dataset of hydrologic characteristics of the Big Sioux aquifer near Sioux Falls, South Dakota Geospatial dataset of hydrologic characteristics of the Big Sioux aquifer near Sioux Falls, South Dakota
The city of Sioux Falls, in southeastern South Dakota, is the largest city in South Dakota. The U.S. Geological Survey (USGS), in cooperation with the city of Sioux Falls, completed a groundwater-flow model to use for improving the understanding of groundwater-flow processes, estimating hydrogeologic properties, and analyzing groundwater and surface-water interactions for the Big Sioux...
Scientific studies that document plant material sourcing and selection in the interior central and western United States from 1994 to 2024 Scientific studies that document plant material sourcing and selection in the interior central and western United States from 1994 to 2024
These data were compiled for a literature review exploring science that informs plant material sourcing and selection in the interior central and western United States. Objectives of our study were to compile and summarize scientific literature that informs plant material selection to synthesize the state of knowledge relevant to decision-making. These data represent scientific studies...
Water classification of the Colorado River Corridor, Grand Canyon, Arizona, 2021—Data Water classification of the Colorado River Corridor, Grand Canyon, Arizona, 2021—Data
These data are a surface water classification map of surface water in the riparian corridor of Grand Canyon between Glen Canyon and Pearce Ferry, Arizona, published in ESRI shapefile format. The map was classified from 0.2 m resolution, multispectral imagery (Sankey and others, 2024) and are the same spatial resolution as the imagery. In order to differentiate between the boundary...
Water-quality data including mercury and methylmercury at selected sites in the Cache Creek watershed, Yolo County, California Water-quality data including mercury and methylmercury at selected sites in the Cache Creek watershed, Yolo County, California
This dataset includes water-quality and sediment data for 647 environmental samples collected at 53 surface-water sites in Cache Creek (Cache C) watershed, Yolo County, California, between December 2009 and April 2019, and data for 190 associated quality-control samples (replicates and blanks). About 90 percent of the samples were collected at the following six primary sites that were...
