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.

Vertical profiles of water-quality data from two sites in Milford Lake, Kansas, August 24-25, 2017 Vertical profiles of water-quality data from two sites in Milford Lake, Kansas, August 24-25, 2017
This U.S. Geological Survey (USGS) Data Release provides vertical profiles of water-quality data collected from two sites in Milford Lake, Kansas, August 24-25, 2017. Data are rounded to USGS significant figures. A multiparameter water-quality sonde was used to measure water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll fluorescence, phycocyanin...
Western Gulf Coastal Plain Louisiana Land Use and Land Cover ground truth observations from 2016 to 2017 Western Gulf Coastal Plain Louisiana Land Use and Land Cover ground truth observations from 2016 to 2017
Collaborative landscape conservation planning is largely limited by the quality of spatial data which can be applied to decision support tools to inform conservation decisions. Conservation entities across the Western Gulf Coastal Plain are taking a collaborative, strategic, landscape scale approach to conservation planning. This effort encourages communication and implementation of...
Earthquake geology inputs for the U.S. National Seismic Hazard Model (NSHM) 2023, version 1.0 Earthquake geology inputs for the U.S. National Seismic Hazard Model (NSHM) 2023, version 1.0
This Data Release contains preliminary versions of two related databases: 1) A fault sections database ("NSHM2023_FaultSections_v1"), which depicts the geometry of faults capable of hosting independent earthquakes, and 2) An earthquake geology site information database ("NSHM2023_EQGeoDB_v1"), which contains fault slip-rate constraints at points. These databases were prepared in...
Regional flood skew for parts of the mid-Atlantic region (hydrologic unit 02) in eastern New York and Pennsylvania Regional flood skew for parts of the mid-Atlantic region (hydrologic unit 02) in eastern New York and Pennsylvania
This data release contains annual peak-flow data through the 2013 water year, specification and output files from flood-frequency analysis of the annual peak-flow data in USGS PeakFQ software, a GIS shapefile of the basin polygons with attributes of site information, basin characteristics, results of flood-frequency analysis, and results of B-WLS/B-GLS analysis of skewness of the annual...
Greenhouse observations of plant herbivore interactions on Lepidium draba to test effects of ontogenic variability Greenhouse observations of plant herbivore interactions on Lepidium draba to test effects of ontogenic variability
Data were collected from an experimental greenhouse study in which Lepidium draba plants were grown from root cuttings to create plants at different ontogenic stages. Plants were arranged in mixed-age and single-age stands and exposed to the Lepidopteran herbivore, diamondback moth caterpillars. The success (biomass gain and surivival) of herbivores, the amount of feeding, and the growth...
Seine Collection Data Along the Michigan Shoreline of the St. Clair-Detroit River System Seine Collection Data Along the Michigan Shoreline of the St. Clair-Detroit River System
These data contain counts of fish species collected with a 1.83 m x 9.14 m bag seine constructed of 1.6 mm Delta nylon mesh. When permitted, five consecutive 15.25 m hauls were made parallel to the shoreline. Sites with smaller shorelines were sampled to the greatest extent possible and distance recorded. The seine was pulled in the upstream direction to allow the net to stay open during...
