Canadian Ice Regime System Database

摘要

Transport Canada has proposed extensive revisions to the Canadian Arctic Shipping Pollution Prevention Regulations (ASPPR 1989). In part, these changes make use of actual ice conditions, and define the conditions in which vessels can navigate in ice-covered waters. The system is based on the quantity of hazardous ice. Transport Canada approached the Canadian Hydraulics Centre of the National Research Council to assist them in developing a scientific basis for the Ice Regime System, which is at present based on operational experience. A seven-step approach was developed to do this. A major part of this process was the development of a comprehensive database that would relate ship damage to ice conditions and environmental factors. This paper describes the development, design and format of the database. It also includes a few examples of the types of queries that can be performed with the information in the database.
