Alaska North Slope coastal plain terraced lake attributes

This dataset consists of a geopackage that has polygon bounding boxes for lakes on Alaska’s northern coastal plain, along with various attributes of the lakes. The goal of the study was to analyze the characteristics of lakes across the coastal plain, specifically focusing on spatial variability in shallow subaqueous terraces. A complete description of the methodologies can be found in Fratkin & Piliouras (in revision). Lakes were identified using the Global Surface Water data product from Pekel et al., (2016) and terraces were mapped using Otsu thresholding on Landsat 8 top of atmosphere satellite imagery with 30 m spatial resolution. Other related properties, such as the lithology around each lake, were determined by calculating zonal statistics over a 1.5 km buffer around each individual lake. Additional data sources for these properties are included in the table in the readme file.
