4.1.1 Introduction

Daily ice charts were collected at the Canadian Ice Service (CIS) from February 25th through March 11th inclusive. These charts represent the best estimate of daily ice conditions at the time of issue, based on an analysis and integration of data from the most accurate available sources, such as shore-, ship- and aircraft-based visual observation and remote sensing devices in aircraft and satellites. The charts (scale of 1:2 million) describe ice conditions by predominant ice type, stage of development and form of ice, and include a 24-hour forecast of the drift of freely moving ice. The boundary lines for different ice conditions, of particular importance to navigation, are indicated by established rules. Ice information is presented in the Egg Code format.
