            "description": "Scientists watched the Arctic with particular interest in the summer of 2012 when the areal extent of Arctic sea ice set a new record low. The behavior of sea ice following such a low extent also interests scientists, but as Arctic sea ice was advancing in the autumn of 2012, so was polar darkness. Fortunately, the VIIRS DNB on the Suomi NPP satellite can see in the dark and acquired this nighttime view of sea ice north of Russia and Alaska on October 30, 2012. During polar darkness (i.e., winter months), VIIRS DNB data allow scientists to observe sea ice formation and snow cover extent at the highest latitudes and to identify clear water where ships can safely navigate.",
