U.S. Geological Survey researchers conducted time-series ground-penetrating radar (GPR) surveys with a Sensors and Software 500-MHz Pulse Ekko Pro system. This data release contains ground-based (ski and snowmobile) as well as airborne common-offset profiles. All profiles are linked to coincident GPS observations. Additionally, common-midpoint data was collected at specific glacier locations. Coincident in-situ data may provide calibration information, and may be composed of any of the following: snow pits and/or snow-pit/snow-core combinations, probe profiles, and ablation stake data. This supplemental information provides estimates of snow properties which may be used to calibrate radar velocity.

Lidar-derived elevation data for Goodwin Glacier, Southcentral Alaska, collected September 22, 2023, Raw Data File 2025-7, releases classified point cloud, digital terrain model (DTM), and an intensity model of Goodwin Glacier, Southcentral Alaska, during minimum snow cover conditions. The survey provides snow-free surface elevations for use in change detection following the landslide that occurred on August 10, 2023, covering a large portion of Goodwin Glacier. Aerial lidar data were collected September 22, 2023, and subsequently processed using a suite of geospatial processing software. This data collection is released as a Raw Data File with an open end-user license. All files can be downloaded from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/31519).

This data set captures changes in glacier covered area across the state of Alaska for the period 1985 to 2020.The data set includes 18 biannual shapefiles each for overall glacier covered area, supraglacial debris area, and debris-free glacier covered area.
