| Summary: | A comparison has been made between the observed ice conditions and those predicted by the Canadian Ice Service (CIS). The predicted ice conditions were obtained from ice charts prepared by the CIS, and the observed ice conditions were made by experienced Ice Observers on board various ice class vessels in different regio ns of the Arctic. The comparison showed that in most cases, the CIS ice predictions provide a reliable description of the actual ice conditions. Although there were differences between the predicted and observed conditions, there was no apparent large bias in the data. Additionally, an analysis was done to compare the Ice Numeral calculated from the observed ice conditions within a single “egg code” region of an ice chart. This analysis showed that there could be wide variation in the Ice Numeral within a single egg code region. NRC publication: Yes |
