It usually reaches its minimum extent in mid-September.
There is simply no question that Arctic sea ice is in the midst of a rapid decline, at rates and to minimum extents unseen in millennia.
Here's one snippet from the center's helpful release: The six lowest seasonal minimum ice extents in the satellite record have all occurred in the last six years 2007 to 20122).
Nine of the lowest years on the satellite record for Arctic sea ice minimum extent have been in the last decade.
The DS procedures for the last two fields are presented in a minimum extent and thus, we did not involve them into next analyses.
The epidisc should carefully overlap, even if in a minimum extent, all the intact epithelium edge around the perforation (Fig. 2).
Summer 2012 saw a spectacular fall in sea ice extent: "The Arctic sea ice September minimum extent reached a new record low in 2012 of 3.41 million square kilometers, 44percentt below the 1981-2010 andrage, and 16percentt below the previous record in 2007".
As indicated in Figure S1, the minimum extent of the lesions always included at least 40% of the BLA while in a small percentage of cases the maximal lesion extension occupied adjacent medial and basal areas.
In 2007, the minimum extent was 1.59 million square miles, he said.
