This repository contains CSV files summarizing tabular data associated with analyses of proglacial geomorphic change presented in Anderson and Shean (2021). The included zip file contains three CSVs summarizing volumetric change, Landsat NDVI values, and longitudinal profiles along valley floors presented in that publication. Each CSV has an associated metadata file contained in the zip file providing details of individual datasets.
This data release is a repository for data presented in Anderson and Shean (2021), a publication looking at topographic change in proglacial and glacier-marginal areas on Mount Rainier between 1960 and 2017. Datasets include all newly derived digital elevation models, shapefiles defining various areas of analysis, and tabular summaries of data presented in figures. See individual child items and original publication for more details.
Photogrammetrically Derived Digital Elevation Models of Mount Rainier Proglacial Areas, 1960 to 2017
This repository contains a suite of digital elevation models (DEMs), derived from aerial or satellite imagery, covering glacier and proglacial areas on Mount Rainier between 1960 and 2017. Data are available for the Emmons, Winthrop, Nisqually, and South Tahoma Glaciers and their associated proglacial areas. These data were used in Anderson and Shean (2021) to calculate DEMs of Difference (DoDs) and assess topographic change in these proglacial settings. Aerial lidar datasets used in that analysis are available through the Washington Department of Natural Resources lidar repository (https://lidarportal.dnr.wa.gov/). The DEMs stored here have been coregistered to the 2008 Mount Rainier aerial lidar dataset. Differencing...
Shapefiles Defining Areas of Analysis for Proglacial Sediment Studies on Mount Rainier, 1960 to 2017
This repository contains suites of shapefiles defining areas of analysis used in Anderson and Shean (2021). Three types of shapefiles are included, each bundled into a zip file: First, polygons delineating areas with elevation changes we judge to be overwhelmingly due to sediment motion (as opposed to snow or ice melt), used to calculate final volumes of change reported in Anderson and Shean (2021). File names indicate basin and DoD interval associated with a given polygon. Second, polygons defining areas used for averaging Landsat NDVI values. Third, regular valley-spanning cross sections used to calculate longitudinal profiles of the valley floors over time. Calculating the minimum elevation across these cross...
