Arctic Changes: Lemire and Crew Explore the Artic

Arctic Changes: Lemire and Crew Explore the Artic (4:21)

In parts of the Arctic, the sea ice is melting. Biologist Jean Lemire and his staff launch a 5-month expedition to explore the Arctic and this phenomenon on a ship called the Sedna.

Arctic Changes: The Sedna's First Battle with Ice

Arctic Changes: The Sedna's First Battle with Ice (6:09)

The first battle the crew must face is the ice concentration off the Labrador Coast of the Canadian Arctic. They must rely on all of their technology to navigate the passage.

Arctic Changes: The Importance of the Greenland Ice Cap

Arctic Changes: The Importance of the Greenland Ice Cap (2:42)

If the Greenland ice cap begins to melt it will have an effect on the Gulf Stream and the level of water in the North Atlantic.

Arctic Changes: Polar Bears and Walruses in Hudson Bay

Arctic Changes: Polar Bears and Walruses in Hudson Bay (6:53)

Polar Bears and walruses must adapt to the diminished ice cover in order to survive.

Arctic Changes: The Sedna Faces Ice at Baffin Island

Arctic Changes: The Sedna Faces Ice at Baffin Island (8:48)

At Baffin Island, the expedition will again face ice. Isabella Bay gives the biologists much to observe.

Wild Arctic: Desperate Caribou on Thin Ice

Wild Arctic: Desperate Caribou on Thin Ice (5:39)

The caribou must wait for things to freeze up before heading for the mainland. As the time grows later and later, caribou are forced out on to thin ice.

Wild Arctic: Caribou Migration and Climate Change

Wild Arctic: Caribou Migration and Climate Change (2:15)

Dolphin and Union caribou migrate in the fall. They are experts at living in the snow, but if the snow hardens due to climate change it will make their ability to find food all the more difficult.

Wild Arctic: Barren Ground Caribou on the Tundra

Wild Arctic: Barren Ground Caribou on the Tundra (3:33)

The barren ground caribou are an important part of the food web in the Arctic tundra. Increased heat from global warming means they will feed less and consequently reproduce less.

Wild Arctic: Weather Changes Invite Parasitic Infection

Wild Arctic: Weather Changes Invite Parasitic Infection (3:05)

Due to changing weather patterns, Arctic species have an increased risk of parasitic infection.

Wild Arctic: Global Warming Affecting Hudson Bay Birds

Wild Arctic: Global Warming Affecting Hudson Bay Birds (8:29)

The Canadian Wildlife Service has been studying birds in the warmest portion of the Hudson Bay. These birds are showing the effects of global warming.

Wild Arctic: Weight Loss Amongst Arctic Walruses

Wild Arctic: Weight Loss Amongst Arctic Walruses (0:55)

As the ice cover decreases, walruses are also affected. They use the ice floes as feeding platforms, but increased melting of these surfaces forces them to swim farther and longer. This has led to weight loss in the walrus population.

Wild Arctic: The Polar Bear's Plight

Wild Arctic: The Polar Bear's Plight (2:54)

The polar bears are facing a major threat from global warming. They have to swim farther between ice floes from which they hunt, and the ice floes are disappearing early.

Wild Arctic: The Caribou's Summer Calving Grounds

Wild Arctic: The Caribou's Summer Calving Grounds (1:58)

The short Arctic summer allows the caribou to travel to their calving ground at a time when the plants are most nutritious.

Wild Arctic: Global Warming and the Bowhead Whale

Wild Arctic: Global Warming and the Bowhead Whale (5:14)

The effect of global warming on the bowhead whale is discussed in this section.

Wild Arctic: Loss of Sea Ice Endangers Arctic Ecosystem

Wild Arctic: Loss of Sea Ice Endangers Arctic Ecosystem (3:39)

The Arctic ecosystem is very fragile; any change in climate will have an effect on the ecosystem. Many species live and are dependent on sea ice, which is rapidly melting.
