Onderaan een foto van de polynya (gat in 't ijs) in de Beaufort Zee. Hogere resolutiefote te vinden in de link (let op groot!!).
Vanop de NSIDC-website (sorry, geen tijd om het te vertalen):
Interestingly, while the chances seem low that September 2006 will set a new record for ice extent, it is close to upsetting 2002 as the record low in terms of ice area. Ice extent is based on summing all regions with at least 15% ice concentration (15% ice and 85% open water). Ice area is the total area of ice once open water areas are removed from the calculation. In other words, ice area can be thought of as the total area of ice if it were squished together so there were no gaps.
A new record low for sea ice area would indicate that the ice pack as a whole is spread out. Much of this diffuse, low-concentration ice is in the vicinity of the polynya. See Figure 3, below, for more details on the polynya.
More on the Unusual Polynya
The polynya mentioned in our previous reports, is extremely unusual. The only time we've seen a similar polynya was in 2000. However, the 2000 formation was much smaller and closer to the ice edge, barely enclosed with ice.
