In 2007, the minimum extent was 1.59 million square miles, he said.
In short, this year's higher sea ice extent is merely due to the fact that last year's minimum extent was record-shattering, and the weather was not as optimal for sea ice loss this summer.
Usually the minimum ice extent is not reached until September, suggesting that further ice loss is likely.
In the case of membrane interfacial proteins whose extents do not cover the lipid bilayer, a minimum protein extent is set to Z = 20 Å and Z = −20 Å.
By comparison, the actual minimum ice extent was 18 percent less than the previous record set in 2007.
Thus the scientific data and literature indicate that this year's minimum Arctic sea ice extent is not just the 6th-lowest in the past 34 years, but most likely the 6th-lowest in at least the past few thousand years.
Now the minimum extent has been nearly reached and the sea is starting to refreeze.
The system is amendable to any crop that can be grown in low bulk density substrates where the emphasis is on transpiration and plant size, while root volume or extent is of minimum concern.
Nine of the lowest years on the satellite record for Arctic sea ice minimum extent have been in the last decade.
Most theories begin with melting sea ice14,32,53,54, as the past 10 years have exhibited the lowest minimum sea-ice extents since satellite observations began, and sea-ice extent is a relatively easy variable to manipulate in models.
