A team of US 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 grueling 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 samples of plankton to help researchers better understand the Arctic ecosystem.
