I came across this article awhile back i wonder if the process is still going on in the Beaufort.
Thanks for posting that.
I am going to try and look into it some more.
One thing is for sure after looking at hundreds of these buoys profiles. The technology and resolution has gotten much better. But another more striking and obvious thing is this layer of warm water between the fresh water(surface) and the higher salinity water(surface) really started to show up after 2003(expecially in the beaufort). You can see ITP32 ran from Oct 5th 2009 to Feb 9th 2010.
You can see the fresh water layer thicken as the cold season went on, even as the buoy moved south. The Surface layer actually goes all the way down to 175M or so over this region. That warm layer is just trapped warm water below the fresh water surface, either from another region, the summer sun, or possibly just recycled warmth trapped from prior summers.Below is one from September 7th 2006 to roughly early September 2007.
You can see The river of warmth under neath the ice. This is also the same 2007 summer that the Navy reportedhttp://imb.crrel.usa...mil/buoysum.htm
That is the site that has the buoy recording the huge jumps in bottom ice melt that started in 2007.
Summer ice melt has been measured at 26 sites, since the International Geophysical Year in 1957. Measurements were made in the summers of 1958, 1959, 1976, 1998, and every year since 2000. The locations of these sites during the summer melt season is illustrated in the map below. The sites can be grouped into three broad geographic regions; the Beaufort Sea, the North Pols, and Intermediate. Both surface and bottom melting is consistly larger in the Beaufort Sea than near the North Pole. Bottom melt in the Beaufort Sea has increased dramatically in recent years.
this is just the tip of the iceberg so to speak. The Russians already released scientific data that came from the ministry of science or whatever they had going. But they are now releasing all of the military data, the British are doing it as well.
We can see just in the small samples of 1957, 58, 59 that melt in those summers was very low. Which also indicates a different kind of arctic then.
One more:(From April 11th to December 23rd 2011), this is my favorite. Because it is in the central arctic basin. You can see the water was around -1.8F while the salinity was pretty high. It is also neat how the surface layer is not as deep That warm water you see there, did not come from solar insolation, that is far to deep. But the surface profile is deep and cold.
