Arctic Ocean freshwater bulge detected


www.bbc.co.uk

UK scientists have detected a huge dome of fresh water that is developing in the western Arctic Ocean.

The bulge is some 8,000 cubic km in size and has risen by about 15cm since 2002.

The team thinks it may be the result of strong winds whipping up a great clockwise current in the northern polar region called the Beaufort Gyre.

This would force the water together, raising sea surface height, the group tells the journal Nature Geoscience.

The most amazing thing this tell me (a mere layman) is that it is possible that the Arctic Ocean "stores" freshwater.

"In the western Arctic, the Beaufort Gyre is driven by a permanent anti-cyclonic wind circulation. It drives the water, forcing it to pile up in the centre of gyre, and this domes the sea surface," explained lead author Dr Katharine Giles from the Centre for Polar Observation and Modelling (CPOM) at University College London.


I think kudos are due for the ESA (European Space Agency) for the data it managed to obtain with it's Polar observation satellite, the Cryosat-2:




"What we seen occurring is precisely what the climate models had predicted," said Dr Giles.

"When you have clockwise rotation - the fresh water is stored. If the wind goes the other way - and that has happened in the past - then the fresh water can be pushed to the margins of the Arctic Ocean.

"If the spin-up starts to spin down, the fresh water could be released. It could go to the rest of the Arctic Ocean or even leave the Arctic Ocean."

If the fresh water were to enter the North Atlantic in large volumes, the concern would be that it might disturb the currents that have such a great influence on European weather patterns. These currents draw warm waters up from the tropics, maintaining milder temperatures in winter than would ordinarily be expected at northern European latitudes.


Well, there is always something to worry about here... those ice caps kept this eventuality contained I suppose.

We live on a planet that's 70% water... is there any doubt that water would be the most vital thing to understand if we want to predict climate effects.

Thanks for reading!

Am I the only one that clicked the "Play Animation" button in the picture in the second post. LOL I actually clicked it a few times before i realized it was just a screen capture.

Haha, I clicked it too.


Good thread topic though. I was unaware of this strange predicament.

I am really curious about how this system works. Hmmm.

In explanation....

This is a Breaking News item, and many of our members, while interested, do not frequent the Fragile Earth Forum... hence the idea that two threads may exist on the same topic under such circumstances. Had I run across this article next week, i would not have posted it because it is no longer within the 36-hour window of opportunity for breaking News here.

Thanks for the redirect link.... it leads to valuable input for our members who focus on such topics.

The model showed a raise in water level to 5cm - I would have thought fresh water is due to ice melt - but I am no expert. I know fresh water seperates from sea water due to the salt content - Much salt content is that which has been leached from the land over time.

Bulge in the Arctic?

Maybe it's just happy to see you!


Just kidding, it is a very interesting find.
I wonder what would happen if all that freshwater made its way into the ocean currents?
Would it really be enough to cause the heating/cooling cycles to stop?

Most of what goes on to create the variety of systems we find man living in and with is a very very complex subject ..The mechanics of it all doesn't reside under one roof of thought ..Our fairly recent ability to accurately collect data sets still falls short of giving us the answers to the whole picture.. and yet we have some people like Al Gore that would make a movie and claim the science is settled ...Unified Theory of Climate: Reply to Comments wattsupwiththat.com... ..So we have a lot of info, and we have a lot of questions, but I think we fall way short on having enough answers to claim, the science is settled .. thanks op interesting subject ..peace
