The annual cycle starts with the maximum extent reached on March 15, 2012. Every summer the Arctic ice cap melts down to its minimum extent before colder weather builds the ice cover back up. This new ice generated on an annual basis is called \"first-year\" ice and is thinner than the older sea ice. The perennial ice is the portion of the ice cap that spans multiple years and represents its thickest component. On September 13, 2012, the sea ice minimum covered 3.439 million square kilometers, that is down by more than 3.571 million square kilometers from the high of 7.011 million square kilometers measured in 1980. The annual maximum extent for 2013 reached on February 28 reached an extent of 15.09 million square kilometers. || ", "hits": 43 }, { "id": 3390, "url": "https://svs.gsfc.nasa.gov/3390/", "result_type": "Visualization", "release_date": "2007-03-17T12:00:00-04:00", "title": "AMSR-E Sea Surface Temperature", "description": "This animation is part of an NSF-funded, international project, Exploring Time.

It can also be used to create on-demand, regional-scale assessments of invasive species patterns and vulnerable habitats. Tamarisk (Salt Ceder) is an invasive plant that typically grows near water and crowds out native species. Tamarisk reflective properties differ from those of its neighboring vegetation throughout the annual life cycle. These different reflective properties can be seen by the naked eye (as in the accompanying seasonal photographs), and can also be seen by satellite sensors. Current Tamarisk infestations and suitable habitats for future growth can be derived from various data sets, including EVI, NDVI, and land cover classifications. || ", "hits": 12 } ] }
