UNDER THIN ICE follows Canadian extreme divers and cinematographers Jill Heinerth and Mario Cyr on a journey to investigate how Arctic wildlife is adjusting to global warming.
The Arctic is a majestic world, home to wildlife rarely seen in the south: bowhead whales, polar bears, narwhals, walrus, seals, zooplankton, algae. At the end of each spring, after long months of darkness, the sun shines for 24 hours a day and all living species gather at the floe edge — where ice meets open ocean — for a feeding frenzy.
But global warming is threatening this ecosystem. Temperatures are rising and the ice sheet is melting at an alarming rate. In the last 40 years, more than 75% of the summer ice cover has disappeared.
Diving with whales, walruses and polar bears, Jill and Mario bring viewers into a majestic underwater world trying to adapt to ice loss and climate change.
Viewers will travel on ice floes with Jill and Mario to Tallurutiup Imanga (also known as Lancaster Sound) in Nunavut, Canada, where they will dive with belugas and narwhals in the open Arctic Ocean. They will follow them to Greenland's Disko Bay to explore the underside of icebergs and discover the luminescent world of algae. Back to Canada in the Naujaat region, they will swim with walruses and polar bears, the supreme predators of the Arctic.
Filmed in stunning 4K, UNDER THIN ICE brings viewers into an awe-inspiring underwater world threatened by melting ice and rapid climate change.
