Geochemical analyses of rock samples collected from the Dora Bay peralkaline igneous complex, Prince of Wales Island, southeastern Alaska Geochemical analyses of rock samples collected from the Dora Bay peralkaline igneous complex, Prince of Wales Island, southeastern Alaska
This data release presents the major and trace element chemistry of rock samples collected by the U.S. Geological Survey (USGS) from surface exposures of the Dora Bay igneous complex (DBIC), located in the southern part of Prince of Wales Island, southeastern Alaska. The DBIC is Early Jurassic in age (Bala and others, 2014) and is U-Th-heavy rare earth element (HREE)-enriched like the...
National Streamflow Statistics (NSS) Application National Streamflow Statistics (NSS) Application
The National Streamflow Statistics (NSS) Application is an online computer application that provides a simple method for applying regional flood-peak streamflow estimates and low flow frequency/duration streamflow estimates.
Enhanced Terrain Imagery of the Allentown 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution Enhanced Terrain Imagery of the Allentown 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution
This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Allentown 30 x 60 minute quadrangle in Pennsylvania and part of New Jersey. It also covers part of the Delaware River Basin. The source data used to construct this imagery consists of 1-meter and 2-meter resolution Lidar-derived digital elevation models (DEMs). The lidar source data were compiled from...
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...
