Polar shipping hazard is a term used to describe the danger of icebergs in the Arctic and Antarctic regions. Icebergs are large chunks of ice that break off from glaciers and float in the ocean, posing a risk to ships due to their size and unpredictability. They can be difficult to spot and can cause significant damage if they collide with a vessel. As such, polar shipping hazards are an important consideration for ships travelling in these regions.
