Video: Arctic polar bears swim in search of sea ice habitat

A new film of Alaska polar bears takes viewers on a journey that only polar bears could lead.

Arctic filmmaker Adam Ravetchsing makes compelling videos by strapping “bear cams” around polar bears’ necks. His "point of view" videos are part of a new United States Geological Survey study to understand how polar bears are responding to the loss of sea ice.

Watch as these polar bears swim for miles through Arctic seas:

Four female polar bears on sea ice north of Prudhoe Bay, Alaska, were collared with cameras in April. The first clips of their daily lives have just been released.

This new technology has the potential to help humans better understand Arctic polar bears, whose activities are difficult to study.

One fact is clear. Polar bear habitat includes sea ice, which is diminishing as a result of climate change.

Unfortunately, this may not be the only obstacle that these incredible animals are forced to face in coming years.

In the Arctic Ocean, attempts at offshore drilling are continuous - and an oil spill could be a major disaster.

Offshore spills would also threaten the coastal plain of the Arctic National Wildlife Refuge, where polar bears build dens in an area that the Alaska state government is trying to open to oil exploration.

Protection of polar bear habitat is vital in both the Arctic Ocean and the Arctic Refuge. Join us in doing what we can to help these magnificent creatures.

How you can help:

The Wilderness Society has a robust program in Alaska that is working to protect Alaska's polar bear habitat and other precious Alaska wildlands. Ways to help:

Support the work of The Wilderness Society. Your gift gives us the resources to respond to threats to Alaska's wildlands at a moment's notice. This includes defending the Arctic from frequent attempts to open more of it to oil and gas development, as well as our energy work that promotes solutions to climate change.

Sign up for WildAlerts for opportunities to weigh in on important wildlands decisions made by the federal government, both in Alaska and throughout the United States.
