Summary

These data comprise 505 unique geospatial raster datasets which describe persistent river ice (aufeis) occurrence within floodplains of select rivers and creeks in the 1002 Area of the Arctic National Wildlife Refuge in northern Alaska. Each raster is derived from a historical observation made by one of five Landsat satellites. Surface reflectance in the green and shortwave infrared wavelengths are used to classify the aufeis occurrence within individual pixels. Pixel values of "1" correspond to aufeis presence while "0" corresponds to its absence. Rasters are generated from cloud and snow-filtered images captured between May and September for the years 1985-2022.

Purpose

We classified aufeis features within the 1002 Area located on Alaska's North Slope using the Normalized Difference Snow Index (NDSI) derived from historical observations made by the Landsat satellite campaign (1985 and 2022) to quantify historical aufeis occurrence and seasonal trends.
