Abstract:
These data describe pack ice characteristics in the Antarctic sea ice zone. These data are in the ASPeCt format.

Quality
Each parameter is assigned a data quality flag as defined below:
Flag 1: Error free Flag 2: Dubious. Non-specific errors Flag 3: Known errors exist that can be fixed Flag 4: Known errors exist that cannot be fixed Flag 5: No ... data - not observed Flag 6: Data in analog format only
