Daily Arctic Sea Ice from August/September 2007
In 2007, Arctic summer sea ice reached its lowest extent on record - nearly 25% less than the previous low set in 2005. At the end of each summer, the sea ice cover reaches its minimum extent and what is left is what is called the perennial ice cover which consists mainly of thick multi-year ice floes. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. But the 2007 minimum, reached on September 14, is far below the previous record made in 2005 and is about 38% lower than the climatological average. Such a dramatic loss has implications for ecology, climate and industry as new shipping lanes open.
This visualization shows 2007 daily Arctic sea ice from from 1 August through 19 September.

Toleo jipya la uonekano huu inapatikana. Mwezi wa Agosti na Septemba 2007 barafu ya bahari ya Aktiki ilifikia kiwango chake cha chini kabisa katika rekodi - karibu 25% chini ya kiwango cha chini cha awali kilichowekwa mnamo 2005. Mwishoni mwa kila majira ya joto, barafu ya bahari hufikia kiwango chake cha chini na kile kinachobaki ni kile kinachoitwa barafu ya kudumu ambayo inajumuisha barafu nzito ya miaka mingi. Kwa mfano, eneo la barafu ya kudumu limekuwa likipungua kwa kasi tangu rekodi za satelaiti zilipoanza mnamo 1979, kwa kiwango cha karibu 10% kwa muongo mmoja. Kiwango cha chini cha mwaka 2007 kilipatikana Septemba 14, na ni chini sana ya rekodi ya awali iliyowekwa mnamo 2005 na ni karibu 38% chini ya wastani wa hali ya hewa. Uharibifu huo mkubwa una athari kwa ikolojia, hali ya hewa na viwanda wakati njia mpya za usafirishaji zinafunguliwa. Hii ni picha ya barafu ya bahari ya Arctic ya kila siku ya 2007 kuanzia 1 Agosti hadi 19 Septemba. "Kutoka tarehe 1 Agosti 2007 hadi 19 Septemba 2007: ""Siku ambazo zimeunganishwa na zinaweza kuunganishwa kwenye picha ya barafu, tafadhali weka sifa kwa hii: NASA, Goddard Space Flight Center, Studio ya Visual ya Sayansi, Shukrani kwa Rob Gersten (GSFC) kwa kutoa data." Data zilizotumiwa katika taswira hii DMSPID: 11 zilizokusanywa na SSM-I 08-01-2007-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09-09
