After Titanic: On iceberg patrol

International Ice Patrol search for icebergs posing threats to ships

The International Ice Patrol was set up in the wake of the sinking of the Titanic 100 years ago after her collision with an iceberg. The liner was on her maiden voyage sailing from Southampton to New York. After the tragedy and the loss of more than 1,500 lives the international community was galvanised to prevent such a disaster from happening again.

In its early days the ice patrol teams used boats, but now they use planes and satellites to make sure ships crossing the ocean are safe, using their vantage point in the sky to spot icebergs posing any potential risk to shipping.

ITV Meridian reporter Nick Harper has spent time on ice patrol with a team of US Coast Guards based in St Johns in Newfoundland - a remote city in Canada, on the edge of the Atlantic.
