ABoVE: Land Cover, Methane Flux, and Environmental Data, Big Trail Lake, Fairbanks AK

Overview

Description

This dataset provides gridded land cover classifications for the area north of Big Trail Lake, an active thermokarst lake in Goldstream Valley (near Fairbanks, Alaska, USA) at 10 cm resolution. Land cover classifications were derived from a supervised random forest classification using RedEdgeMX and multiSPEC4C multispectral drone imagery, normalized difference vegetation index (NDVI), and the USGS 3D Elevation Program (3DEP) digital surface model (DSM) elevation data. RedEdgeMX data was collected in July 2021 on and multiSPEC4C on 2019-08-04. Additionally, gridded microtopography and slope estimates were derived at 1m resolution. Field samples were collected at 15 sites across the study area in June 2021 and August 2022. Field data include methane (CH4) and carbon dioxide (CO2) fluxes, gross primary production (GPP), SIMPER microbial community analysis, methanogen abundance, soil characteristics, and meteorological characteristics. Gridded products are provided in cloud-optimized GeoTIFF format, field data are provided in comma-separated values format, and sample location photos in JPEG format are contained within a compressed file.
