This is reported at the UIUC site. Included is this:

"One week after dipping below 4 million square kilometers Northern
Hemisphere sea ice area and setting the new historic record NH sea ice
minimum, there is currently 3.58 million sq. kilometers sea ice area. This
new minimum is almost 11% lower than the previous historic minimum. "

There are still a few weeks of melting before the autumn freeze starts.



Any idea why the measurement of the area of ice is so different as that at
NSIDC - 5.26? They both agree it's a record but can't agree on the value.
NSIDC tends to overestimate the amount of ice - it still shows ice in
Hudson Bay and Siberian rivers, for example - but I don't see this as being
enough to account for the difference.
