Victoria Strait

When the CCGS Amundsen breaks through a 10-foot (or thicker) piece of ice, it rides on top of it first, the whole front of the ship sliding onto the sheet as the boat comes to a stop. Then the ship, 100 yards long and weighing 6,000 tons, crushes down, and its sharp hull splits the ice and pushes the fragments to either side.

Fishermen off Australia who accidentally caught a whopping 6.3 metre basking shark have provided scientists with a rare opportunity to study the second - biggest fish on the planet.
