Data

This data release contains discrete chlorophyll data, specifically corrected chlorophyll a, uncorrected chlorophyll a, and pheophytin pigments, from inland waters in the Illinois River Basin for 1981–2023. These data are discrete samples (collected in the field and analyzed in the laboratory) of plankton (suspended algae) and periphyton (benthic algae) from lakes, streams, rivers, canals...

These data utilize existing land cover products and elevation information to provide information on changes on barrier islands and barrier shorelines along the north central Gulf of Mexico coast. Specifically, this data release includes information on changes in subaerial land, habitat types, and high-tide flooding for barrier islands and barrier shorelines along the north central Gulf...

This dataset consists of Structure-from-Motion (SfM) - derived point clouds and highly detailed orthomosaic images of four roadcut exposures covering the upper part of the Harrell Shale, the full Brallier Formation, the full Foreknobs Formation, and the lower part of the Hampshire Formation at Baker, West Virginia. For each roadcut exposure, two datasets are published: an orthomosaic...

This data release includes uranium-lead isotopic data collected from metaplutonic rocks of the New Hampshire Plutonic Suite and metasedimentary rocks of the New Hampshire Sequence. Rock samples were collected by Arthur Merschat, Greg Walsh, and Ryan McAleer. Samples were processed and analyzed by Arthur Merschat and Ryan McAleer. Uranium-lead isotopic data was collected using a sensitive...

The U.S. Environmental Protection Agency (EPA) National Coastal Condition Assessment (NCCA) is a nationwide survey of coastal and estuarine water quality. During the 2015 EPA NCCA, samples were collected at 732 sites for analysis of algal toxins and cyanotoxins at the Organic Geochemistry Research Laboratory (OGRL) at the U.S. Geological Survey Kansas Water Science Center (KSWSC) by...

These tabular data are the summarization of land use/land cover related variables within the Delaware River watershed at the 1:24,000 scale using the xstrm methodology. Variables being counted as land use/land cover related include all land use and land cover data. Outputs consist of tabular comma-separated values files (CSVs), and parquet formatted files for both the local catchment and...

These tabular data are the summarization of natural environment related variables within catchments of the Delaware River watershed at the 1:24,000 scale using the xstrm methodology. Variables being counted as natural environment related include soils/geology, lithology, elevation, slope, landform (geomorphon) and others. Outputs include tabular comma-separated values files (CSVs) and...

Groundwater discharge points to coastal waters can be identified and quantified using natural electrical and temperature data. In August 2022, U.S. Geological Survey (USGS) collected water-borne electromagnetic induction and temperature along selected transects within Hen Cove on Cape Cod, Massachusetts, following a spatial survey of bed sediment temperature. Handheld thermal infrared...

This dataset contains 253 samples from 11 occurrences of Chloropyron molle subsp. molle, and 3 occurrences of Chloropyron molle hispidum. Genomic markers were generated from ddRAD loci and analyzed using the Stacks v2.60 pipeline. The genotypes for all samples are provided in a VCF file with 40,707 independent loci . A companion sample data file is provided with sample names, and...

The Rare Plant Occurrences geodatabase is an element occurrence data system with about 10,000 records of rare plant observations on the 6 northernmost California Channel Islands. It is a live database created with the purpose of bringing together in one space all discoverable historic and current information on the localities of about 180 rare and sensitive plants of the northern Channel...

This dataset includes information on detections of Bachman's Sparrow, Northern Bobwhite, and Red-cockaded Woodpecker at 161 locations in Georgia, USA. In addition to detections of birds and corresponding detection covariates (date, time, temperature, and observer), habitat metrics derived from satellite imagery and on-the-ground vegetation measurements are included.

The products presented here document conditions at the Little Saint Francis River chat pile restoration site near Fredericktown, Missouri in July 2019. Imagery was collected shortly after the initiation of restoration actions. Images were collected using low-altitude flights of unoccupied aerial systems (UAS, or “drones”) and processed using structure-from-motion techniques to generate...
