Resolving the spatial and seasonal pattern of riverbank erosion on the Koyukuk River, Alaska, 2016-2022

This dataset describes measurements of inter-annual to sub-seasonal riverbank erosion rates on the Koyukuk River, Alaska, over the period 2016-2022. The data are used in the paper: “Geyman, E., Douglas, M., Avouac, J.-P. and Lamb, M. Permafrost slows Arctic riverbank erosion, in review (2024).” The dataset contains two sets of measurements: (1) riverbank displacement estimated from Sentinel-2 optical satellite imagery (10 meter (m) resolution) over the period 30-Aug-2016 to 13-Jul-2022, and (2) riverbank displacement estimated from Planet optical satellite imagery (3 m resolution) over the period 31-Aug-2016 to 01-Oct-2022. The first dataset is based on comparison of Sentinel-2 satellite acquisitions from the start and end of the study interval. The second dataset analyzes 65 PlanetScope image mosaics (for an average of 9 observations per year). The Matlab code used to analyze the Sentinel-2 and PlanetScope imagery, as well as to process the sub-seasonal displacement estimates, is included in the file “Code.zip”.
