Overview

Data consist of ice observations from U.S. Coast Guard vessels operating on the Great Lakes and from Coast Guard shore stations reported via teletype messages and ice logging forms. Observations include ice thickness and concentration, weather conditions, and ice breaking activity. Data from 1961/1962 through 1966/1967 have been processed to a standard format and sorted by year and stations, and are available via FTP as ASCII files, one for each of the five lakes.
