Data

The data are a set of fluorescent images that were generated to support the development of a machine learning model. The approach combines fluorescence imaging, deep learning, a mobile application, and a data management system for automated and real-time oil spill assessment. The dataset is comprised of 1,530 fluorescence images from two distinct oil types, a napthalenic crude oil (NACO)...

This data release presents model inputs and outputs to support an investigation of occurrence and temporal changes of imidacloprid from the U.S. Geological Survey National Water Quality Network spanning 77 sites between 2013 and 2022. Imidacloprid is a neonicotinoid insecticide used to control a wide range of agricultural and non-agricultural insect pests. The Seasonal Wave and...

We monitored breeding birds at Whiskey Island, Louisiana between March through July from 2015 to 2020. We surveyed all available habitat by foot, using high-powered spotting scopes and binoculars to search for and identify nesting birds. We documented species, abundance, habitat, location, and breeding behavior for each bird that we observed to be breeding. We modeled the counts of...

The data were collected to examine the impact of thiamine deficiency and replacement with thiamine on the swimming ability of American eels.

Note: this data release has been superseded by version 2.0, available here: https://doi.org/10.5066/P14P7RT6.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...

NASA’s lunar exploration objectives, which include both robotic and human missions to the surface, require data products with high spatial resolution and accuracy. Using rigorous photogrammetric methods, we have co-aligned thousands of high-resolution images from the Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) [Robbinson et al. 2010] of the lunar north and south...

These field data such as first floor elevation and bathymetric surveys were collected to support development of coastal mapping products and advance storm response and recovery in Alaskan coastal communities. The data consists of essential community infrastructure elevation data to better understand flood exposure and support analysis of flood mitigation solutions, bathymetric surveys to...

This dataset contains measurements of in situ benthic biofilms from rivers of northwest Alaska during summer and fall 2016-2019. Measurements were made using a Benthotorch (bbe Moldaenke, Kiel, Germany) hand-held fluorometer, which distinguishes taxa (cyanobacteria, green algae, diatoms) and provides estimates of standing biomass.

Major, minor, and trace element data, as well as backscattered electron images, were collected for clinopyroxene crystals in alkaline silicate rocks (phonolite, tephriphonolite, latite, phonotephrite, and pyroxenite) of the Bear Lodge and Mineral Hill alkaline complexes, Wyoming. Samples of alkaline rocks thought to represent early and later stages of magmatism, based on observed...

This data release comprises geochemical point analyses of magnetite by electron probe microanalyzer (EPMA) and sample imagery acquired by a combination of scanning electron, reflected light, and transmitted light microscopy. Analyzed elements include Fe, Ti, Al, Mn, Mg, V, Si, Ni, Cr, and Ca. Samples are from the Taurus porphyry Cu-Mo(-Au) deposit in the Yukon-Tanana upland of eastern...

This data release includes fluorometer measurements of Rhodamine WT dye concentration and turbidity acquired during a tracer experiment performed on the Big Piney River near St. Robert, Missouri on August 25 - 26, 2021. The primary goal of this experiment was to perform a conservative tracer injection to better understand transport and dispersion processes related to environmental DNA...

A reach of the Sacramento River near Glenn, California, was selected as a field site to test the performance of a software-defined radar (SDRadar) developed by the University of Southern California. The SDRadar can be deployed from an uncrewed aircraft system (UAS) and is designed to measure river depth. This data release contains measurements of river depth collected with two different...
