Polar bear's epic nine day swim in search of sea ice

Image

A polar bear swam continuously for over nine days, covering 687km (426 miles), a new study has revealed.

Scientists studying bears around the Beaufort sea, north of Alaska, claim this endurance feat could be a result of climate change.

Polar bears are known to swim between land and sea ice floes to hunt seals.

But the researchers say that increased sea ice melts push polar bears to swim greater distances, risking their own health and future generations.

    • Interesting story, but it's probably best to dismiss the BBC's interpretation instantly due to their extreme bias towards anything linked to "global warming".
      So I found the article in some other websites. The Alaska Dispatch has a more detailed article, and it doesn't take too long before some interesting things slap you in the face.

      How often does one particular scaremonger in this forum scream, "it's NOW we're concerned about - NOW"!!! Ok, so read the article, "With data collected over a two-month period in 2008", the article says. So this bear did its epic swim in 2008, not 2010/11. Notice how the BBC doesn't tell you this happened in 2008, I wonder why not?

      The article continues, "By the time scientists caught up with the polar bear again in October 2008..." So remember, the bear was tracked for two months, therefore it was probably caught in August - the time when Arctic sea ice is at its lowest, and they're surprised to find a polar bear swimming across open water?
      Polar bears have been spotted well over a hundred miles from land/ice. Reports suggest they have been seen a couple of hundred miles from land, and while this may have been an 'epic' journey, it is probably not that unusual. The article itself states, "Our observation confirms that yes, indeed, polar bears are capable of, they have the ability to undergo these extraordinary behaviors such as long distance swimming." Exactly, maybe that's why the polar bear's Latin name is "Ursus Maritimus"

      What's more, can anyone say this is unusual, a first, unprecedented? No, because, as the article states "No one else has been able to provide data like this before," Durner said in an interview from his Anchorage office Tuesday."

      Why do so many people just see what they want to see in an article?

      Good points and research. Should earn you negative votes. The villagers just love to light those torches. Reminds me of God and Noah "How long can you tread water, Noah?" Then again, what is a normal swim for a polar bear? And is this a new worlds record? And can we generalize from an single observation? Sorta like correlating the sale of ice cream with murders. There is a correlation. Just not cause and effect.

      Nice one IceKat!

      It reminds me of the article that was run last year on all the mainstream outlets of a with photos of a male polar bear with a dismembered cub's head in it's mouth.

      The article screamed "POLAR BEARS RESORT TO CANNABALISM", possibly due to climate change/and or global warming of course (ie: you and I are causing this to happen).

      Oh dear the photos were something gruesome, but what the article didn't say was that this is common behaviour of male predators; to kill the cubs so that there will be less competition for food and also to that the female will be ready to mate more quickly.

      Just like you pointed out, it's not so much what they say, it's how they report what they say, and more importantly it's what they don't report.

      Infanticide

      Infanticide is a common practice in most mammals. Male lions use infanticide to get rid of offspring in a newly acquired pride that are not genetically related to the male coalition. Solitary males are also capable of killing the offspring of an encountered pride (Packer 1983). Female lions have also been observed to kill cubs from a rival pride, but they would never kill cubs from their own pride. The dead offspring are sometimes consumed as an energy source and other times they are simply just eradicated for the sake of it. Older cubs and sub-adults have a better chance of being able to escape incoming infanticidal males than younger cubs (Urban 2002).

      Infanticide is very advantageous to incoming males in that they are getting rid of offspring that do not carry their genes (Packer 1983). The other advantage of killing the offspring of the former owners of the pride is that a female will quickly enter estrous following the infanticidal event. As a result, the incoming males are then capable of copulating very soon after overtaking the pride (Viljoen 2003). However, following the takeover it usually takes a lioness 6-9 estrous cycles in order to become impregnated again. Packer hypothesizes that this duration of time is caused by the female adapting to the new male’s sperm rather than the female being infertile (Packer 1983).

      "...and more importantly it's what they don't report." exactly right, it's bias by omission.

      People read between the lines; polar bear + ice + climate change = "oh, this must be bad, really bad". People are indoctrinated into believing that the Arctic is melting. It is, and does at regular intervals and varying amounts, but it is not the downward spiral people are led to believe. The ice will 'recover', probably sooner than most people think.
      Thanks for your comment.

      Do you think Greenland's ice is going to recover as well? Sooner being 10 years, 100 years? Most Americans or most of the rest of the world? Climate change is looking pretty fucked up from what I see and hear reported about record heat and cold and rain and snow. These new sweetheart storms that drop a month of normal rain in just days seem to state that major change is in the works.

      Are you saying that humans have no affect on the climate so don't trouble our little heads? When I was a kid, in the seventies, the Ice in the north pole was impenetrable. Now not so much. Maybe the earths core is the problem, or the sun?

    • treewolf39:

      I agree. But there is no evidence that suggests this is a unique event. The animal did lose body weight during it's trip which does indicate a traumatic period, but not all wild animals have the luxury of a regular meal and losing body weight is not unheard of.

      Polar bears eat the blubbery, fat parts of seals, and little protein. Their water comes from the process of breaking down the fat - they don't need to drink from pools of water like some other animals do.
      To say the bear was swimming all that time may be misleading too. There was no mention of currents and how far the bear may have drifted.

      Actually yes, polar bears float pretty well, better than you or I would, because of the layers of blubber they have. Again, I'm not saying this polar bear's epic journey was a walk in the park, but it may not be all that unusual.

      Absolutely not, humans do have an impact on the climate in many ways.
      I'm not concerned about Greenland, it isn't about to turn into a green and pleasant land whilst flooding the rest of the world - you'll see.

      --------" Why do so many people just see what they want to see in an article?"------

      Despite all your blathering about the earth cooling, and temperatures being lower than normal for this 7 day period, or that 2 min. period blah blah blah-------

      What I see is an article about about a polar bear that had to swim nearly 500 miles to reach ice floes that are it's normal habitat and lost it's cub in the process.

      Polar bears are dying. And all you care about is your stupid greed and ego.

      What I see in this article is that you are lying to people----and the article is proof.

      I hope you are happy Dr. DoNothing.

      It is all about ego with you----you just HAVE to make everyone agree with you no matter what the cost. Well, here is the cost.

      This is not about making the whole human race feel guilty-----this is about a few people who SHOULD feel guilty-----but have no conscience at all. People like you.

      Good for you, old man. Getting that off your chest probably did you the world of good.
      But just because you're sucked in by an article that doesn't quite tell things as they were, it doesn't mean everyone else is, or that those who are more intelligent than you are greedy, in the pay of someone, or egotistical.
      Polar bears are dying, but not at the rate the scaremongers like Greenpeace and the WWF want you to believe. If one of those organisations were to tell people Polar bears are not in danger just imagine the money they'd lose. Oh but only "deniers" are in this for the money, aren't they? Wake up man!!!

      Well, you do seem to be totally uneducated on this subject.

      And it isn't "ONE polar bear," either. Perhaps if you read or watched news that's authentic, you'd be able to quickly learn -- and hopefully even FEEL -- how devastating this all is, not only for our endangered polar bears, but for all the other hundreds (possibly thousands) of endangered or soon-to-be species.

      And, pretty soon, we can add "human being" to that endangered list, unless everyone starts learning, then doing something ABOUT, these true horrors.

      The scientific community seems to have reached a consensus => that believes when species die other species fill in their emptied place. So, if you want to convince the population that Evolution is Real one great way to do that is to kill off some species FORCING others to fill in.

      Your compassion does not trump their agenda. You can cry alone or we could all join you in a nationwide group cry but neither will stop the ball from reaching the pins.

You could easily achieve that by making them as smaller interlocking blocks (for transport to locution area).

    • Ahem..".there's no difference between human species and animal species"? And they want to legalize marijuana? I suppose that nut job abortionist Kermit whatshisname who was recently charged with 8 counts of murder would be one of your heroes? We are much different than the animals, mind you. (but sometimes I wonder.....) It is this devaluing of life that gave us Hitler, Stalin, Mao, Castro, etc. Folks like Peter Singer, who believe as you do, openly advocate infanticide. Sick. EthicalVegan, it is very easy to excuse human life as mere commodity, and when that happens, human life is disposed of like the trash. We are stewards of the earth, and of the animals we must treat with care and dignity, never abusing them, always showing them concern and care. But to say we're no better than animals? I beg to differ.

      Animals know how to treat the planet? WTF?
      I'm sensing a bit of delusional idealism here. The primary genetic drive of all life seems to be dominance and expansion.
      You can see that with ANY species that is no longer confined by natural barriers and limits that they can't overcome: All the so-called "weed" and "pest" species.

      Any life form that gets the chance will use up as much resources as it is able to. Humans are no different to any other form of life in that respect.

      -Hopefully we'll use our vaunted "intelligence" to put limits on our primitive, purely "natural" drive to use everything up.

      Yes, animals know how to treat the planet. They don't destroy in their greed to get more money to get more things to be "better" than their neighbor. They operate on instinct and survival. They were here before we were, and I suspect they'll be here after we're gone; unless we manage to obliterate the earth.

      Unfortunately, I have yet to see much in the way of evidence that the humans with the power have any intention to even attempt to put limits on our destructive ways.

A polar bear chomps down on a baby seal to feed itself for survival - humans beat down on a baby seal for profit. A bit of a difference. So I suppose the comment about "loving ourselves to death" is very prophetic.

      Brazilians, Venezuelans and probably THEIR TWO YEAR OLDS make better car fuels. Russians make mutually wonderful agreements with the Chinese while we hand them the keys to the car no questions asked.

      I hate to say it, but I'm so much more concerned with the well-being of my fellow man than a polar bear, especially since the bear is clearly designed by nature to swim long distances in search of food and shelter.

      Hell, at least the polar bear survived. Just sayin...

      There's no "buzz" to kill here. The point of the polar bear story is that it's the canary in the coalmine.
      The fact that the bears have to travel so far for food and land means that the area of the icecaps are in serious decline and this will continue to affect animal life all down the line. This is just the very beginnings of the problem.

      Humans are next, as you yourself note: Northern hemisphere winters are already a lot more icy due to all that freed up cold seawater flowing down from the north.

    • Only people who get anywhere from tree to six months of below 30 temps deny the global warming theories. Funny thing on -40 degree days most everyone around here denies it. The thing is I watched the animal channel about a polar bear momma who they said would kill her 1 or 2 cubs if she didn't catch a seal which she did. What a relief. And what's more on them hot summer days in Winnipeg I always felt bad for the polar bears because they want it cool. I saw a story about some zoo that installed a huge pool for the polar bears during the sumner months & I thoughts all zoos should be forced to do the same if they have polar bears.

    • This situation has BUSINESS OPPORTUNITY pasted all over it. What is needed is FAKED ICE for the bears. It would also restore reflection of solar radiation. Win~Win => two birds, one stone. Hmm. If there was a chemical that could be added to ocean water that would assist the H2O to freeze at a higher temperature say 40 degrees... the polar bears would be In Like Flint.

      Perhaps something that would increase ocean water bonding but only on the surface (as in in contact with air i.e. needing air as its catalyst; that way it wouldn't do its "freeze effect" on deeper waters) PLUS the miracle chemical would turn the surface water a white color.

    • Oh but wait, didn't you hear, the ice isn't melting. It is all one big giant conspiracy.

      http://www.alaskadispatch.com/dispatches/arctic/8473-polar-bear-swims-across-arc...

      Excerpt:

      "Along the way, during the swimming journey that went on far longer than scientists have to-date recorded, she lost her cub. Durner suspects it died from exhaustion during the long, 426-mile swim from land to pack ice, but there's no way to know for sure.

      The floating ice pack was farther off shore than usual -- a trend attributed to melting sea ice and climate change. And it was over deep waters which aren't as food-rich as the shallower continental shelf, over which summer pack ice in years past has been found.

      By the time scientists caught up with the polar bear again in October 2008, she had traveled hundreds of miles eastward toward Canada. Her cub was gone, she had stopped lactating and she had lost a lot a weight.

      In the past, polar bears haven't had to swim as far to reach the ice, Durner said, adding that the mother bear probably had no idea what she was getting herself into."

      And just to add on edit:

      Don't be fooled by the oil loving AGW deniers who will post links like this to take this all out of context. The message remains the same: the Arctic ice is melting at an excelerated pace and polar bears are having to swim farther then usual to find ice because of that fact. It wasn't the fact that the bear was swimming, but how far she had to swim looking for ice because it wasn't there that cost the life of her cub and perhaps her own. The fact that polar bears can swim is a DUH to those of us who know about polar bears. Don't be distracted by the smoke and mirrors to once again divert from the serious crisis we face in this world that is not only affecting polar bears, but walrusus, seals and penquins in these areas as well.

    • It is tragic what we have done to our environment. Today--it's the polar bears who suffer. Tomorrow --it will be US scrambling to find a rocky crag to hang onto.

      Destroying the planet is giving mankind the Hate Energy it needed to go on to new & great inventions. Had we not polluted the waters as we have would we now have REVERSE OSMOSIS water filtering systems?

      If we hadn't 3/4 destroyed this planet where would the impetus come from for building Hubble telescopes and such to search us out another planet?

      What's been done, had to be done. The longer our collective necks stay on the guillotine looking UP at the big blade the more & better inventions we get. Were we to wait for inventions to naturally occur it would be a THOUSAND YEARS for new inventions to amble along and fall on Newton's head.

      The Polar bear bacon is toast but it is for a great purpose. US.
