The new results, based on data from a NASA Earth-orbiting spacecraft, provide further evidence for the rapid, ongoing transformation of the Arctic's ice cover. pdboyer Tue, 14 Jul 2009 14:31:55 GMT http://books.nap.edu/catalog.php?record_id=12631&utm_medium=etmail&utm_source=National%20Academies%20Press&utm_campaign=NAP+mail+new+7.21.09&utm_content=Downloader&utm_term= During the 1990s, a government program brought together environmental scientists and members of the intelligence community to consider how classified assets and data could be applied to further the understanding of environmental change. As part of the Medea program, collection of overhead classified imagery of sea ice at four sites around the Arctic basin was initiated in 1999, and two additional sites were added in 2005. Collection of images during the summer months at these six locations has continued until the present day. Several hundred unclassified images with a nominal resolution of 1 meter have been derived from the classified images collected at the 6 Arctic sites. To assist in the process of making the unclassified derived imagery more widely ... pdboyer Thu, 23 Jul 2009 15:51:23 GMT http://www.arcus.org/ArcticAlive/index.html Arctic Alive! is a distance-learning environment for learners to be transported virtually to unique and remote locations within the arctic region. Arctic Alive! is not an information Internet site but an interactive, real-time, and unique web-based education program. It uses a variety of delivery methods and e-learning strategies to deliver arctic research to the classroom. pdboyer Sun, 31 Jan 2010 17:37:39 GMT
