This dataset is a single comma-delimited text file (.csv). Data include the name of lakes where sampling occurred, approximate geographic coordinates of each lake, historical dynamics of the lake, and indication of measurements taken at the lake.

This dataset is a single comma-delimited text file (.csv). Data include the name of lakes where samples were obtained, the historical dynamics of that lake, the sampled community type, and the dry mass of annual new growth. Shrub community measurements are a combination of understory mass from quadrat harvests and shrub stem mass derived from published allometric equations.

This dataset is a single comma-delimited text file (.csv). Data include the name of lakes where samples were obtained, soil pH, electrical conductivity (EC), water content (VWC), and bulk density (BD) of soil core samples within organic soil horizon in lake-margin wetland plant communities.

This data release provides seven datasets of soil and vegetation data from lake margin soils from throughout the Yukon Flats National Wildlife Refuge. Data includes multiple lakes that are defined as either stable or drying. Lake margin vegetation communities include graminoid, shrub, and forest. Sols are separated into organic and mineral layers. Microbial data includes different phospholipid fatty acids and soil enzyme activity data for multiple enzymes involved in C,N, and P cycling. Data also includes information on respiration rate constants (k) and labile substrate pool (Ao) from soil incubations. Other soil chemical attributes such as soil pH, electrical conductivity, percent C and percent N are also included.
PURPOSE: The inclusion in the National Wild and Scenic Rivers System (NWSRS) of the Lower Sheenjek River, located in northeastern Alaska, is proposed. The river is a 277-mile free-flowing, unpolluted tributary of the Porcupine River. The study area encompasses the lower 99 miles of the river flowing through the Yukon Flats National Wildlife Refuge. The river outside the study area, within the Arctic National Wildlife Refuge, is already included in the NWSRS. The entire study area is eligible and suitable for inclusion in the system, meeting the criteria for classification as wild. The area is characterized by outstandingly remarkable cultural, wildlife, scenic, and recreational values and has historically provided...

Total and organic carbon values from soil samples taken from the Yukon River Basin, Alaska. These samples were used to create a relationship between total carbon and organic carbon for samples which were only run for total carbon.

This dataset includes soil properties and microbial data from lake margin soils throughout the Yukon Flats National Wildlife Refuge. Data include multiple lakes that are defined as either stable or drying. Lake margin vegetation communities include graminoid, shrub, and forest. Sols are separated into organic and mineral layers. Microbial data includes different phospholipid fatty acids and soil enzyme activity data for multiple enzymes involved in C,N, and P cycling. Data also includes information on respiration rate constants (k) and labile substrate pool (Ao) from soil incubations.

This data package includes 481 geospatial vector polygons of historic fire perimeters associated with National Wildlife Refuges in Alaska. These polygons, originally held within the Alaska Large Fire Database (ALFD), were reviewed and found to have geospatial inaccuracies with respect to the fire they represent. They were corrected and updated based on a variety of remote sensing resources; the Monitoring Trends in Burn Severity (MTBS) database (https://www.mtbs.gov/viewer/index.html), geospatial rasters of historic fire activity derived from Landsat 1-9 imagery in the Google Earth Engine(https://earthengine.google.com) environment, and historical air photos acquired through EarthExplorer (https://earthexplorer.usgs.gov/)....
