New Ice Study uses Historic Citizen Science Data

1 November 2020

A new paper just published in The Cryosphere capitalizes on past citizen science data from CRREL, UAF, and NWS to understand changes in ice thickness in river and lakes across Alaska from the 1960's to present. River and lake ice thickens at varying rates geographically and from year to year.  Slower ice growth was most pronounced in northern Alaskan lakes over the last 60 years. Western and interior Alaska ice showed more variability in thickness and safe travel duration. This analysis provides a comprehensive evaluation of changing freshwater ice in Alaska.
