Arctic Ice Retreat Creates Giant Swells For The First Time

The Beaufort Sea in Arctic Ocean is usually frozen. The water is covered with ice most of the time. But researchers have recorded giant waves, as high as 16 feet, just north of Alaska. Swells of that size have stunned the scientists because they have the potential to break up Arctic ice much faster than expected, thanks to rapid global warming. The North is changing, and it’s changing fast as the sea ice retreats due to global warming.

The largest single wave in Arctic Ocean was 29 feet

Jim Thomson of the University of Washington recorded the wave measurements with the help of sensors. The house-size waves were measured during a September 2012 storm. Thomson told The Washington Post that 16 feet swells were the average. The biggest single wave was about 29 feet. Findings of the study appeared in the Geophysical Researchers Letters recently.

Until recently, the Arctic Ocean remained ice-covered throughout the summer, so there were no waves to measure. But the area of open water is increasing. Thomson said the Arctic ice never retreated more than 100 miles during summer in the past. But in 2012, it retreated well over 1,000 miles. The expanded ice retreat leaves much of the Beaufort Sea ice-free by the end of summer.

Arctic Ocean could soon see ice-free summer

Wind blowing across the open water creates whitecaps, which slowly turn into small waves. These small waves consolidate into giant waves that carry more energy in a single punch. The size of swells increases with the travel distance over the open water. An increased expanse of open water means bigger waves. Giant swells would increase the pace of ice breakup in the Arctic Ocean, eventually causing an “ice-free summer.” It will have wide-ranging implications for the ice-water-air system.

Thomson and his colleagues are conducting a large project this summer to assess the relative importance of the ice retreat compared to melting. They have to use sensors beneath the surface because satellites provide only a rough estimate of wave heights. Satellites don’t give precise measurements for storm events.

  1. Cool I just found out arctic sea ice extent is exactly the same as 1974.

    Your prayers to Gaea worked! Bless you for caring so much!

    BTW your 3% of scientific community was based on a falsified study. Just make up facts and present them.

    Actually climate realists are the ones that believe in climate change. The climate changes all the time – it can’t be denied. What is in doubt and has been shown false by the data so far is that adding CO2 to the atmosphere will create massive temperature increases due to positive feedbafeedbacks of dubious nature. And of course alarmists don’t believe in climate change at all. They believe the world should be static.

    How unscientific you religious zealots are.

  2. Over the past 30 years Arctic ice ( 15% or more ice) has varied from about 5 million km2 in the summer to 15 million km2 in the winter. Winter ice has varied less than 10% in that time.
    Check out the NOAA sea surface temperature map. The northern oceans are much warmer than normal the southern colder this is the one and only reason for the ice variation at the poles.

  3. One of the 3% of the international scientific community who believes climate change is a hoax, are you? Or just a blowhard Republican. Alas. Bantering with idiots.

  4. You might want to learn the difference between surface ice and permanent ice. I doubt if learning is one of your strong points. Related to ostriches, are you?

  5. I guess now I need to recommend reading comprehension classes. Didn’t I mention per official government records Arctic is at a 10 year high and well above average for this time of year? Hmm – yes I did. The Antarctic stiff was just an aside , so was the global ice extent- but to have near record global ice extent does not portend good things for you global warming religion.

    So to summarize: brush up on google skills, learn to read charts and take reading comprehension at the local high school extension.

  6. The arctic is not the antarctic; but I guess your charts and google forgot to tell you. I repeat, you can’t fix stupid. Have fun at the Tea Party convention.

  7. You might to fix your stupid by looking at some government ice extent charts. Arctic ocean is currently at a 10 year high and well above the 30 year average. I guess those waves didn’t cause all the ice to go away.

    Antarctic (recently reconfirmed by NASA amid reports of data problem) is at record high since we have startednto take measurements. Overall ocean ice extent is now 3rd highest ever recorded. None of this is Fox news. You just have to learn how to use google and really government stats and charts.

  8. There are whores in my home town that take pictures of their shaven stretched out butthole and they show the picture to their potential john, then they stand there asking their potential john if they want it or not.

  9. I am no man-made global warming believer but the people below talking about the Antarctic ice being at a 10 year high are at the wrong end of the globe. The arctic ice… is north. Antarctic… is south.

  10. You might to fix your stupid by looking at some government ice extent charts. Arctic ocean is currently at a 10 year high and well above the 30 year average. I guess those waves didn’t cause all the ice to go away.

  11. You know if he arctic ice extent is currently at a 10 year high? Antarctic is at record levels since measurements started. Where did this dinasaur of an article come from?

  12. It took two years to get around to reporting this? The global hystericals must be searching for needles in their haystack of lies to come up with this one.

  13. You likely get your science from Fox And Friends. Alas. You can’t fix stupid. Do you believe science is there for profit/entertainment?
