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...

An Updated Vs30 Map for California with Geologic and Topographic Constraints An Updated Vs30 Map for California with Geologic and Topographic Constraints

This data release provides a map of the time-averaged shear-wave velocity in the upper 30 m (Vs30) for California using the method described by Thompson and others (2014). There are two adjustments to the algorithm described by Thompson and others (2014), which is built on the geology-based Vs30 map by Wills and Clahan (2006). In this data release, we use the Wills and others (2015)...

This repository contains code for the analysis of Wamboldt JJ, Nelson JE, Thomas LM, Steiner JN, Hebert JL, Erickson RA, Putnam JG. Quantitative method development to determine feed consumption using a dye. North American Journal of Aquaculture The purpose of the repository is to document what analysis was run for publication and is intended for an archive rather than a production or...

Analytical and diagnostic validation of a molecular test to detect and discriminate IHNV genogroups U and M Analytical and diagnostic validation of a molecular test to detect and discriminate IHNV genogroups U and M

Infectious hematopoietic necrosis virus (IHNV) is an acute pathogen of salmonids in North America, Europe and Asia that is phylogenetically classified into five major virus genogroups (U, M, L, E and J). The geographic range of the U and M genogroup isolates overlap in the North American Columbia River Basin and Washington Coast region, where these genogroups pose different risks...

Annotated bibliography of grazing effects on amphibians and their habitats (ver. 2.0, February 2022) Annotated bibliography of grazing effects on amphibians and their habitats (ver. 2.0, February 2022)

This database contains literature citations and associated summaries pertaining to livestock grazing effects on amphibians and their habitats, with an emphasis on the Oregon spotted frog (Rana pretiosa) and other listed/sensitive wetland-breeding amphibians in the western United States. This is not meant to be an exhaustive list, nor did we perform a systematic meta-analysis; rather...

Annual (1986-2020) land-use/land cover maps of the Santa Cruz Watershed and Tucson metropolitan area, Arizona Annual (1986-2020) land-use/land cover maps of the Santa Cruz Watershed and Tucson metropolitan area, Arizona

Annual (1986-2020) land-use/land cover maps at 30-meter resolution of the Tucson metropolitan area, Arizona and the greater Santa Cruz Watershed including Nogales, Sonora, Mexico. Maps were created using a combination of Landsat imagery, derived transformation and indices, texture analysis and other ancillary data fed to a Random Forest classifier in Google Earth Engine. The maps contain...

Annual Marbled Murrelet Abundance and Productivity Surveys Off Central California (Zone 6), 1999-2021 (ver. 4.0, May 2022) Annual Marbled Murrelet Abundance and Productivity Surveys Off Central California (Zone 6), 1999-2021 (ver. 4.0, May 2022)

Since 2017, U.S. Geological Survey, Western Ecological Research Center (USGS WERC) partnered with California State Parks to continue long-term, annual at-sea surveys to estimate at-sea abundance and juvenile (i.e. hatch-year) productivity of Marbled Murrelets (Brachyramphus marmoratus) in U.S. Fish and Wildlife Service Conservation Zone 6 (central California: San Francisco Bay to...

Anthropogenic Disturbances and Natural Variables in the Conterminous United States Linked to Catchments and Buffers of the National Hydrography Dataset Plus Version 2.1 Anthropogenic Disturbances and Natural Variables in the Conterminous United States Linked to Catchments and Buffers of the National Hydrography Dataset Plus Version 2.1

This USGS data release contains landscape variables representing anthropogenic disturbances to stream habitats and natural variables summarized within local and network stream catchments of the National Hydrography Dataset Plus Version 2.1 (NHDPlusV2.1) as well as a 90 meter local and network buffer of stream reaches throughout the conterminous U.S. The source datasets compiled and...

The dataset includes specifics on liver tissue and blood plasma anticoagulant rodenticide concentrations measured using high-performance liquid chromatography-tandem mass spectrometry.

Antioch Dunes evening primrose (Oenothera deltoides subsp. howellii) juvenile and adult abundance across the known range, California, USA (2019) Antioch Dunes evening primrose (Oenothera deltoides subsp. howellii) juvenile and adult abundance across the known range, California, USA (2019)

These datasets provide information on total plant cover, Normalized Difference Vegetation Index, and Antioch Dunes evening primrose (Oenothera deltoides subsp. howellii) abundance within grids across the subspecies' extant range in California. These data support the following publication: Jones, S.F., Kennedy, A., Freeman, C.M. et al. Intensity of grass invasion negatively correlated...

Apatite and zircon U/Pb and fission track geochronologic and thermochronologic data along the Fall Line of the southeastern United States Apatite and zircon U/Pb and fission track geochronologic and thermochronologic data along the Fall Line of the southeastern United States

This data release contains apatite and zircon U/Pb and fission track data for six samples collected along the Fall Line of the southeastern United States, from Virginia to the Georgia-South Carolina border. The data resolve phases of rapid exhumational cooling in the Permo-Triassic, additional cooling in the Jurassic-Early Cretaceous and slower cooling since the middle of the Cretaceous...
