Airborne electromagnetic, magnetic, and radiometric survey of the Mississippi Alluvial Plain, Mississippi Embayment, and Gulf Coastal Plain, September 2021 - January 2022 Airborne electromagnetic, magnetic, and radiometric survey of the Mississippi Alluvial Plain, Mississippi Embayment, and Gulf Coastal Plain, September 2021 - January 2022
Airborne electromagnetic (AEM), magnetic, and radiometric data were acquired September 2021 to January 2022 along 27,204 line-kilometers (line-km) over the Mississippi Alluvial Plain (MAP), Mississippi Embayment, and Gulf Coastal Plain. Data were acquired by Xcalibur Multiphysics (Canada), Ltd. with three different airborne sensors: the 30Hz TEMPEST time-domain AEM instrument that is...

Body weight and weight change during course of study, estimates of food and brodifacoum consumption, observations of test birds during feeding trial and at necropsy, hematocrit, and prothrombin time
Attribution of stream habitat assessment data to NHDPlus V2 and NHDPlus HR catchments within the Chesapeake Bay Watershed Attribution of stream habitat assessment data to NHDPlus V2 and NHDPlus HR catchments within the Chesapeake Bay Watershed
This data release links habitat assessment sites to both the NHDPlus Version 2 and NHDPlus High Resolution Region 02 networks using the hydrolink methodology. Linked habitat sites are those compiled by the Interstate Commission on the Potomac River Basin (ICPRB) during creation of the Chesapeake Bay Basin-wide Index of Biotic Integrity (Chessie BIBI) for benthic macroinvertebrates (https...
Parasite sample voucher numbers and 28S rRNA alignment file for parasites collected from California Giant Salamander (Dicamptodon ensatus) from Webb Creek, in the Bear Creek Redwoods Preserve in Santa Clara County, California, USA Parasite sample voucher numbers and 28S rRNA alignment file for parasites collected from California Giant Salamander (Dicamptodon ensatus) from Webb Creek, in the Bear Creek Redwoods Preserve in Santa Clara County, California, USA
Multi sequence file (.msf) file used to construct a 28S rRNA phylogenetic tree of species of Euryhelmis and other heterophyid trematodes. Sequences were generated from metacercariae samples at U.S. Geological Survey National Wildlife Health Center (NWHC) and compared for base pair similarities with publicly available sequences from GenBank using BLAST (https://blast.ncbi.nlm.nih.gov...
Seasonal Blue Water Evapotranspiration 1986 – 2020 for the Croplands in the High Plains Aquifer Region Seasonal Blue Water Evapotranspiration 1986 – 2020 for the Croplands in the High Plains Aquifer Region
Estimation of irrigation water use provides essential information for the management and conservation of agricultural water resources. The blue water evapotranspiration (BWET) raster dataset at 30-meter resolution is created to estimate agricultural irrigation water consumption. The dataset contains seasonal total (1 May to 30 September) BWET time series (1986 – 2020) for the croplands...
