Explorers attempt to conquer Arctic Ocean

A team of American adventurers is set to begin a dangerous and unprecedented journey across the Arctic that will see them rowing from Canada to Russia over the next 30 days. The gruelling trek has billed as one of the world's last great firsts across a landscape that was covered in year-round ice just years ago. The rowers will also be collecting data on whale feeding habits and collecting samples of plankton to help researchers better understand the ecosystem in the far north. Al Jazeera's Gerald Tan has the story.
