Foreword

MANICE is the authoritative document for observing all forms of Sea, Lake and River Ice, as well as Ice of Land Origin. It describes the standard procedures of the Canadian Ice Service for observing, recording and reporting ice conditions.

MANICE has been prepared in accordance with internationally recommended terminology and symbology established by the World Meteorological Organization (WMO). It describes procedures that are completely compatible with World Meteorological Organization nomenclature (cf. 1), coding and observing practices, along with additional procedures, coding and symbology adapted for Canadian use or, in the case of icebergs, used in conjunction with the International Ice Patrol (IIP).

This manual has been reviewed, revised and updated by the Operations and Field Services divisions of the Canadian Ice Service. This document has been updated to reflect changes in technology, practices, colour codes and iceberg message coding. Although amendments are required and important there were not enough significant changes to publish a completely new version of the standards manual. Therefore this edition will be considered a revision of version 9 published in April 2002.
