00:13sea ice. Dr. Krumpen is with Germany's Alfred Wegener Institute, the world's leading polar
00:20research organization. His mission is to determine the thickness of sea ice. They check it twice
00:36a year in winter and summer. The team flies east from Greenland towards Svalbard Island.
00:46They spend long, cold days tracing a grid pattern over the Fram Strait. They call the
00:53tethered torpedo they trail an iceberg. It shoots laser beams at the ice surface to calculate
01:00its thickness. And the goal is to get very long transects of survey data and to get more
01:08or less a representative idea about this thickness at a certain location.
01:14Over the past two decades, the iceberg has seen a definite thinning of sea ice. It
01:20is 20% less now in summer than it was in the year 2000.
01:24every one you have government that really means a whole is not the matter that it is because
01:24you can't be afraid of it until you reach a distance. It wants you to see something different
