Canadian Inuit hunter Jimmy Kulak from Resolute Bay, Cornwallis Island photographed by Hartley in 2011. Hartley says many of his Arctic trips pass through indigenous communities to reach the Arctic Ocean. "They all say the same thing, which is the winters are shorter and a lot warmer," he says.

Two polar bears photographed by Horvath at night on October 10. The animals were close to the ship and crew scared them away with the bang of a flare gun, for the safety of crew and the bears.

Hungarian photographer Esther Horvath has been documenting Arctic Ocean sea ice since 2015. "We live in a time where ... this environment (is) changing so fast, that if you don't do something now it will completely disappear," she says.

As icebreakers are used to help ships navigate an increasingly open Arctic Ocean, these ships will have a crucial role in the years to come.

Craig says her documentary will take more than a year to film and says she has plans to visit the Russian Arctic and the Northwest Passage (a route between the Atlantic Ocean and the Pacific Ocean around the top of continental North America). "The Arctic feels very remote," she says, "but what's happening in the Arctic is impacting everyone, everywhere."
