Let's Take the Measurements
In this area the cold Labrador Current meets the warm Gulf Stream and the temperature differences of up to 20°C / 68°F produce dense fog. The combination of icebergs, fog, storms, fishing vessels and busy trans-Atlantic shipping lanes makes this area one of the most dangerous for ships.
Navigators therefore need all the help they can get, so the International Ice Patrol uses the following size categories to identify icebergs.
