ABoVE: Active Layer Soil Properties and Multispectral Images, Imnavait Creek AK, 2024

This dataset provides active layer soil properties measurements and multi-spectral Unmanned Aerial Vehicle (UAV)-based imagery from Imnavait Creek, Alaska, USA in 2024 in support of the NASA Arctic and Boreal Vulnerability Experiment (ABoVE) Airborne Campaign. Soil properties include active layer thickness, soil roughness height, soil organic matter, bulk density, root biomass, soil carbon and nitrogen, and mineral texture. Soil samples were collected from the top 30 cm from 2024-08-17 to 2024-08-23. A DJI Matrice 210 v2 UAV was flown on 2024-09-04 to collect optical (RGB) images, optical derived digital surface model (DSM), and multispectral images. Normalized difference vegetation index (NDVI) was calculated from multispectral images. This dataset provides a unique, comprehensive, and simultaneous characterization of the active layer, supporting analyses of fine scale heterogeneity of soil processes in the active layer in areas over permafrost and the drivers that influence topsoil organic matter in Arctic foothills tundra. The data is provided in comma separated values (CSV) and GeoTIFF formats.
