Mini­mum record of drift ice in the arc­tic

The Nor­we­gi­an Meteo­ro­lo­gi­cal insti­tu­te is fol­lo­wing the drift ice deve­lo­p­ment in the arc­tic sin­ce 30 years now, and simi­lar insti­tu­ti­ons in other arc­tic nati­ons do the same with simi­lar results: the­re has never been less ice than the­re is now. Even in Sep­tem­ber 2007, the mini­mum year so far, the­re was more ice than now. The­re are about 3 mil­li­on squa­re kilo­me­t­res ice less than in 1979, an area 8 times lar­ger than Nor­way (wit­hout Spits­ber­gen).

It is not only the area that is lost, but also the chan­ge in qua­li­ty that makes experts worry. In the past, arc­tic sea ice used to be lar­ge­ly of lar­ge, strong, thick floes mul­ti-year ice. The­se have lar­ge­ly dis­ap­peared. Now, most of the ice con­sists of much thin­ner one-year ice, which does not compa­re to the stron­ger, older ice in thic­k­ness, sta­bi­li­ty and as a habi­tat for the arc­tic eco­sys­tem.

The drift ice is curr­ent­ly far north from any coast in the Spits­ber­gen archi­pe­la­go, but the ice loss is far more dra­ma­tic on the other side of the arc­tic, north of wes­tern arc­tic Cana­da, Alas­ka and Sibe­ria.
