Hurtigruten cruise line introduces a new way to see what lurks beneath the world's most remote polar waters. On its expedition ships, the company is introducing an underwater drone that streams real-time video of orcas, leopard sharks, penguins and other creatures beneath the water. Or passengers can wear masks with digital displays that may make them feel like they're on a dive deep in the ocean Hurtigruten plans to start by outfitting two hybrid-powered ships -- the Roald Amundsen and the Fridtjof Nansen -- with the new underwater drone. "[W]ith underwater drones on our ships we can take our guests to areas less explored than the surface of Mars," company Chief Executive Daniel Skjeldam said in a statement.
