org.nsidc:G00805 U.S. Coast Guard Unknown Great Lakes Surface Ice Reports from U.S. Coast Guard Boulder, CO USA National Snow and Ice Data Center http://nsidc.org/data/g00805.html 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. scientific research U.S. Coast Guard Unknown Great Lakes Surface Ice Reports from U.S. Coast Guard Boulder, CO USA National Snow and Ice Data Center http://nsidc.org/data/docs/noaa/g00805_surface_ice_reports/index.html 19611110 2004 publication date Complete Unknown -93 -76 49 41 NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Atmosphere > Atmospheric Temperature > Maximum/Minimum Temperature EARTH SCIENCE > Cryosphere > Snow/Ice > Ice Depth/Thickness EARTH SCIENCE > Cryosphere > Snow/Ice > Ice Extent EARTH SCIENCE > Cryosphere > Snow/Ice > Lake Ice EARTH SCIENCE > Terrestrial Hydrosphere > Snow/Ice > Ice Depth/Thickness EARTH SCIENCE > Terrestrial Hydrosphere > Snow/Ice > Ice Extent EARTH SCIENCE > Terrestrial Hydrosphere > Snow/Ice > Lake Ice NASA Global Change Master Directory (GCMD) Instrument Keywords VISUAL OBSERVATIONS NASA Global Change Master Directory (GCMD) Platform Keywords GROUND STATIONS SHIPS ISO 19115 Topic Categories climatologyMeteorologyAtmosphere inlandWaters None Climatology Freshwater Ice Ice Cover Ice Navigation IDN_NODE GSFC/NSIDC Lake Ice LAKES Seasonal Ice NASA Global Change Master Directory (GCMD) Location Keywords Continent > North America > USA Continent > North America > United States Of America Continent > North America > United States Of America > Great Lakes > Detroit River Geographic Region > Mid-latitude 7 NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Atmosphere > Atmospheric Temperature > Maximum/Minimum Temperature NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Snow/Ice > Ice Depth/Thickness NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Snow/Ice > Ice Extent NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Snow/Ice > Lake Ice NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Terrestrial Hydrosphere > Snow/Ice > Ice Depth/Thickness NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Terrestrial Hydrosphere > Snow/Ice > Ice Extent NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Terrestrial Hydrosphere > Snow/Ice > Lake Ice None None NSIDC USER SERVICES mailing
