Unlike dolphins, polar bears cannot swim forever. They have to come to the land eventually. Also, they use floating pieces of ice as a base from which to hunt seals. It is harder for them to hunt in the open sea. So no, polar bears would not survive in the open sea, at least, not in the long term.

Why do polar bears need open seawater?
Polar bears are chatergorized as aquatic mammals. They get most of their food from the ocean so no ocean = no food. Plus polar bears over-heat really easy because of their thick fur and a good swim helps to cool them off.
What do polar bears need to change to live in the open sea?
A polar bear would have to change: -It's body fat/hair so it wouldn't drag it down. -Webbed feet to swim better.
How far have polar bears been seen away from land in open water?
200 miles
What is a polarbears only predator?
The only natural predator of polar bears is the orca, or killer whale. While adult polar bears are apex predators in their Arctic habitat, orcas can occasionally prey on cubs or young bears, particularly when they venture into open water. However, this predation is relatively rare, as polar bears are formidable hunters themselves.
Why can't polar bears be in the sunny areas?
That's really not true. Polar bears can be in sunny areas without any adverse effects whatsoever. As a matter of fact, much of where they live is out in the open and exposed to the sun.
How old is the polar bear before they can see?
Polar Bears generally can see at the age of 10 months old. This can vary from each individual bear but generally the average age is 10 months
Why do polar bears have small jaws?
They have small jaws because their "cheek skin" stretches and although their jaw is small, they could open it wide. Therefore, they mix in and the polar bear could open it's mouth wide.
In what kind homes do polar bears live?
Polar bears do not usually live in any sort of shelter. However, a pregnant polar bear female digs a den and enters a state similar to hibernation, which she remains in until the cubs are born and developed enough to travel with her while she hunts for food. When it is very windy, polar bears dig a shallow depression to sleep in so that they can shelter themselves from some of the wind.
Why wouldn't a polar bear survive in the open sea?
Because it needs to land our a iceburg to catch fish off
Could polar bears emigrate to England?
It all depends on how quickly the arctic ice cap melts. So far only a couple of polar bears have hitched a ride on Greenland Ferry's, but they went back when they saw unemployment rates in Scotland. The Jury is still open on this one.
Is the killer whale a predator of the polar bear?
Yes. Remains of polar bears and other large animals have been found in the Orca's (killer whale's) stomach. Orca whales have been known to come onto beaches and polar bears also swim in the ocean.Polar bears have indeed been found in the stomachs of killer whales. Polar bears are often seen swimming in open water, there is nothing stopping a killer whale from taking it as a prey item. See related link below, for more information on the killer whales, diet and eating habbits.
How can polar bears swim during global warming?
A 6-year-long study recently found that polar bears can swim for great distances. GPS collars were attached to 20 female bears, some with cubs. The swims documented lasted from 17 hours to nearly 10 days and covered between 33 and 427 miles (54 and 687 kilometers) in the southern Beaufort Sea. There are no earlier studies on polar bear swims, but there was not enough open water in recent years for bears to swim such distances. Polar bears rely on sea-ice in the Arctic to hunt their prey, seals, but this ice is melting earlier every year. Scientists fear that cubs especially will not survive long swims. Twelve of the 20 bears had cubs when the collars were fitted, but when 10 of the 12 were recaptured a year later, only 6 had cubs. U.S. Geological Survey (link below).
