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.

Concentrations of pesticides in silicone bands as passive samplers and sediment in Pinnacles National Park and Bureau of Land Management lands in San Benito County, California, 2019-2021 Concentrations of pesticides in silicone bands as passive samplers and sediment in Pinnacles National Park and Bureau of Land Management lands in San Benito County, California, 2019-2021
To better understand the potential pesticide exposure, samples were collected from locations along two creeks in Pinnacles National Park and four creeks in nearby Bureau of Land Management (BLM) lands. Silicone bands were used as passive sampling devices (PSD) staked in the creek and above in the air (above the water line). Sampling was conducted in the summer from 2019 to 2021. PSDs...
Great Lakes tributary pharmaceutical water samples from water year 2018 Great Lakes tributary pharmaceutical water samples from water year 2018
This data release provides water chemistry results and quality assurance data for samples collected from Great Lakes tributaries in the states of Minnesota, Wisconsin, Michigan, Indiana, Ohio, and New York. In total, 158 chemicals were analyzed which are primarily pharmaceuticals. Between one and four water samples were collected at 37 sampling locations between November 2017 and July...
Tagging date, site, turtle size, and migration and foraging behavioral data for loggerheads (Caretta caretta) nesting at three sites in the Gulf of Mexico from 2011–2019 Tagging date, site, turtle size, and migration and foraging behavioral data for loggerheads (Caretta caretta) nesting at three sites in the Gulf of Mexico from 2011–2019
Tagging information, including migration and foraging behavioral data, for female reproductive loggerhead marine turtles (Caretta caretta) that were satellite tagged at nesting beaches at Gulf Shores (Alabama [AL]), Dry Tortugas National Park (DRTO, Florida [FL]), and Everglades National Park (ENP, FL) from 2011–2019. Variables include the tagging date, tagging site, the curved carapace...
Urban landcover differentially drives day and nighttime air temperature across a semi-arid city Urban landcover differentially drives day and nighttime air temperature across a semi-arid city
Semi-arid urban environments are undergoing an increase in air temperatures, both in average temperatures and in the frequency and intensity of extreme heat events. Within cities, different varieties of urban landcovers (ULC) and their densities influence local air temperatures, either mitigating or increasing heat. Currently, understanding how various combinations of ULCs influence air
An Unvegetated to Vegetated Ratio (UVVR) for coastal wetlands of the Conterminous United States (2014-2018) An Unvegetated to Vegetated Ratio (UVVR) for coastal wetlands of the Conterminous United States (2014-2018)
This USGS Data Release represents geospatial data sets which were created to produce an Unvegetated to Vegetated Ratio (UVVR) for coastal wetlands of the conterminous United States (2014-2018). The following listed image products were generated 1) Annual spatial datasets (rasters) from 2014 to 2018 each containing 4 bands (Band 1: Unvegetated land fraction; Band 2: Vegetated land...
