Observations and Machine-Learned Models of Near-Surface Permafrost along the Koyukuk River, Alaska, USA
This dataset contains GeoTIFs (raster) and GeoPackages (vector) that map observations of near-surface permafrost and not-permafrost from a field campaign conducted near the village of Huslia, AK along the Koyukuk River and its floodplain in July 2018. These data were collected as part of a campaign...
