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.

Evaluating regulations and surveillance as risk-mitigation to the emerging amphibian pathogen Bsal- Data release Evaluating regulations and surveillance as risk-mitigation to the emerging amphibian pathogen Bsal- Data release
Results of a literature search performed December 1, 2020. The tables in this document summarize the publications fitting in this search criteria and are split into the publications that update the list of international species that could carry Bsal (Appendix 1 Table S1). Number of individual live amphibians imported in categories of urodelan (salamander, newt, and related taxa) species...
ObsNetQW---Assessment of a water-quality aquifer monitoring network ObsNetQW---Assessment of a water-quality aquifer monitoring network
The establishment of an efficient aquifer water-quality aquifer monitoring network is a critical component in the assessment and protection of groundwater quality. A periodic evaluation of the monitoring network is mandatory to ensure effective data collection and possible redesigning of existing network. This package assesses the efficacy and appropriateness of an existing water-quality...
Cortisol Concentration Data from Polar Bear (Ursus maritimus) Hair Collected in the Bering, Chukchi, and Beaufort Seas, Alaska, 1983-1989, 2004-2006, and 2008-2016 Cortisol Concentration Data from Polar Bear (Ursus maritimus) Hair Collected in the Bering, Chukchi, and Beaufort Seas, Alaska, 1983-1989, 2004-2006, and 2008-2016
This data release contains one table which includes the concentration of cortisol from polar bear (Ursus maritimus) hair and morphometric data from some of the captured bears. We assayed concentration of cortisol in hair (HCC) from polar bears captured in the Alaska Beaufort, Bering and Chukchi seas during 1983-1989 and 2004-2016. Fields include the individual polar bear identifier...
NHD-RC: Extension of NHDPlus Version 2.1 with high-resolution river corridor attributes NHD-RC: Extension of NHDPlus Version 2.1 with high-resolution river corridor attributes
This hybrid medium-resolution national hydrography dataset with river corridor attributes (NHD-RC) for the conterminous United States (CONUS) was created by merging lentic and lotic attributes from the high-resolution NHDPlus (U.S. Geological Survey, 2020) into the medium-resolution NHDPlus Version 2.1 (U.S. Geological Survey, 2016). NHD-RC includes attributes from an additional 5.4...
Date for Methane gas ebullition dynamics from different wetland vegetation communities in Big Cypress National Preserve (Florida) are revealed using a multi-method, multi-scale approach Date for Methane gas ebullition dynamics from different wetland vegetation communities in Big Cypress National Preserve (Florida) are revealed using a multi-method, multi-scale approach
Methane emissions from peat soils are highly variable both in space and time and are influenced by changes in certain biogeochemical controls (i.e. organic matter availability; redox potential) and/or other environmental factors (i.e. soil temperature; water level). Consequently, hot spots (areas with disproportionally high emissions) in wetlands may develop where biogeochemical and...
Radiometric Ages and Descriptive Data for Holocene Corals From Southeast Florida Radiometric Ages and Descriptive Data for Holocene Corals From Southeast Florida
This data release compiles descriptive information (location, water depth, etc.) and radiometric ages from corals collected through the Southeast Florida Continental Reef Tract (SFCRT; fig. 1). The database includes data from studies published between 1977 and 2015 as well as previously unpublished data. The samples were originally collected using coral-reef coring or other geologic...
