Group: Summary

   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. These data were provided to NSIDC by the NOAA Great 
   Lakes Environmental Research Laboratory (GLERL), along with documentation. The 
   documentation, Great Lakes Environmental Research Laboratory Great Lakes 
   Surface Ice Reports, 1961-1966, is included here. Data from 1970/1971 through 
   1993/1994 are available on microfilm. The original ice reporting forms for 
   these years were filed as part of the ice operations files of the Ninth 
   District U.S. Coast Guard Ice Navigation Center, Cleveland, OH. Data from 
   1994/1995 through 2003/2004 are available via FTP in a single .tar file for 
   each ice season.

   Note that no editing or quality control has been performed on this data set. 
   Microfilmed records are difficult to use, as they are sorted by date and time 
   only, and contain extraneous information. The electronic data from 1994/1995 
   forward are raw teletype reports. These are not in a consistent format, and 
   also contain extraneous information. NSIDC obtained these data from a NOAA 
   National Weather Service public FTP server. The National Weather Service 
   obtained the data from the United States Coast Guard Headquarters. NSIDC was 
   unable to locate a responsible party within NOAA who could provide NSIDC with 
   a new source for the data. Therefore, the records end in 2004. Users may wish 
   to contact the U.S. Coast Guard for information on obtaining the individual 
   ship reports.
