Photogrammetric Data Set, 1957-2000, and Bathymetric Measurements for Columbia Glacier, Alaska

By Robert M. Krimmel


Major changes in the length, speed, surface altitude, and calving rate of Columbia Glacier, Alaska have been recorded with stereo vertical photography acquired on 119 dates from 1957 to 2000. Photogrammetric analysis of this photographic record has resulted in precise measurement of these changes. From 1982 to 2000 Columbia Glacier retreated 12 kilometers, reduced its thickness by as much as 400 meters, increased its speed from about 5 to 30 meters per day, and increased its calving rate from 3 to 18 million cubic meters per day. All photogrammetric data for Columbia Glacier from 1957 to 2000 are included in this report, as well as supplemental data of ice-dammed lake surface levels, stagnant ice ablation rate, forebay bathymetry, ground control, and camera calibrations. These data are contained in 481 files, all preserved on a CD-ROM included with this report.
