Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Velocity surveys and three-dimensional point measurements of basic water-quality constituents in nearshore Lake Erie in the vicinity of Villa Angela Beach and Euclid Creek, Cleveland, Ohio, June 10–12, 2019, and August 19–21, 2019 Velocity surveys and three-dimensional point measurements of basic water-quality constituents in nearshore Lake Erie in the vicinity of Villa Angela Beach and Euclid Creek, Cleveland, Ohio, June 10–12, 2019, and August 19–21, 2019
Water velocities and water-quality constituents were measured along planned survey lines, which were generally perpendicular to the shoreline and spaced 100 meters apart, over an approximately 2.3-mile section of nearshore Lake Erie on June 10-12, 2019 (survey 1), and August 19-21, 2019 (survey 2), using a 1200 kHz acoustic Doppler current profiler (ADCP), a YSI 6920 V2 multiparameter...
Data on Zerene silverspot butterfly and early blue violet responses to herbicide treatments from 2018-2019 greenhouse experiments Data on Zerene silverspot butterfly and early blue violet responses to herbicide treatments from 2018-2019 greenhouse experiments
Herbicide treatments were applied to Zerene silverspot (Speyeria = Argynnis zerene zerene) post-diapause larvae and early blue violets (Viola adunca), the larval host plant of the Zerene silverspot butterfly, in two greenhouse experiments in 2018-2019. Treatments included distilled water for untreated (U), Agri-Dex (A), Nu Film IR (N), clopyralid (C), clopyralid with Agri-Dex (CA)...
Novel genetic resources for Clubshell freshwater mussels (Pleurobema clava, P. oviforme) for enhanced conservation Novel genetic resources for Clubshell freshwater mussels (Pleurobema clava, P. oviforme) for enhanced conservation
Here we provide public access to two mitochondrial DNA sequence alignments, multi-locus microsatellite DNA genotypes, morphometric measurements and details on all specimens utilized in Morrison et al., 2021 (In press).
Code associated with analysis and modeling of benthic and pelagic inorganic nutrient processing rates at the interface between a river and lake Code associated with analysis and modeling of benthic and pelagic inorganic nutrient processing rates at the interface between a river and lake
In this data release the authors have code and 'data' that are used to model how sediment flux and water column processing of soluble reactive phosphorus (SRP), ammonium (NH4/NHX) and nitrate (NOX). The file 'README.md' contains background information on how to access and use the data and code files.
Modeled estimates of altered hydrologic metrics for all NHDPlus v21 reaches in the Chesapeake Bay watershed Modeled estimates of altered hydrologic metrics for all NHDPlus v21 reaches in the Chesapeake Bay watershed
Data are modeled estimates of flow status (inclined, diminished, or indeterminant) for 12 published hydrologic metrics (HMs) that characterize main components of flow regimes (duration, frequency, magnitude, timing, and rate of change). Model estimates came from random forest models independently built for each HM that predict flow status category using drainage area and previously...
