Ever since the Titanic, there has always been some element of risk when navigating ships through icebergs. Through the years, scientists have attempted to come up with ways of eliminating or highlighting icebergs so passing ships will be alerted to their danger. Since icebergs move around, and are commonly veiled by thick fog or rough seas, they can often be masked from view or a ship's radar. After trying to paint icebergs, plant radio transmitters on them, and even detonating explosives on them, they still posed a high risk to ships that have to eventually pass that route.
