Historical and projected future land change and ecosystem carbon stocks for California Historical and projected future land change and ecosystem carbon stocks for California
This dataset consists of annual raster maps of ecosystem carbon stocks, land use and land cover classes, and transition probabilities for the State of California during historical (1985-2020) and projected future (2021-2100) time periods. Data are simulation model output from the The Land Use and Carbon Simulator (LUCAS; Sleeter et al. 2022) run under different climate and land...
Results of Virus Isolation and Serology testing on Influenza A Virus Samples from Lesser Scaup (Aythya affinis) and Greater Scaup (Aythya Marila) Results of Virus Isolation and Serology testing on Influenza A Virus Samples from Lesser Scaup (Aythya affinis) and Greater Scaup (Aythya Marila)
These data describe the results of virus isolation from oropharyngeal/cloacal swabs and testing of sera by a commercial blocking enzyme-linked immunosorbent assay (bELISA) and hemagglutinin (HA) specific testing by microneutralization (MN) and hemagglutination inhibition (HI) for Lesser Scaup in both the Atlantic and Pacific Flyways and Greater Scaup in the Pacific Flyway. These data...
Indiana Amphibian Pathogen Surveillance data release Indiana Amphibian Pathogen Surveillance data release
Data in this dataset were collected as a part of a surveillance project for reintroduction of a state endangered species in Indiana. This data was collected in the field by state biologists and sent to the USGS National Wildlife Health Center (NWHC) for testing of four amphibian pathogens, Batrachochytrium dendrobatidis (Bd), Batrachochytrium salamandrivorans (Bs), Ranavirus, and...
An Inventory of Past Mine Production Footprints in Alaska, Including Land Disturbance and Potential Above-Ground Resources, Derived from 2018-2023 World Imagery An Inventory of Past Mine Production Footprints in Alaska, Including Land Disturbance and Potential Above-Ground Resources, Derived from 2018-2023 World Imagery
This data release contains two vector polygon shapefile datasets that delineate footprints of land surface disturbance and waste that may represent potential above-ground resources resulting from past mining in Alaska. These footprints were mapped on 2023 World Imagery at the location of currently inactive Alaska Resource Data File sites of past mining production.
