One of the largest icebergs in the world a hulk three times the size of Greater London will now be known as Melting Bob after a six-year-old boy won a competition to give it a name. Max Dolan, from Winchester, beat 500 entrants in a naming contest set by the Scott Polar Research Institute at Cambridge University, which has undertaken to use the name as it tracks Bob on its journey through the Southern Ocean. The 101-mile-long iceberg, which was known by its codename C19A, is expected to roam the seas for a decade as it melts from its present size of 1,985 sq miles to nothing. It is now 1,600 miles to the southwest of New Zealand.
