Satellite‐based estimates of monthly sea ice volume exports through Fram Strait for the years 2003 to 2008 are presented. These obtained from individual satellite observations thickness, area, and drift. First, freeboard is inferred ICESat laser altimeter then converted thickness estimates. Sea area drift derived AMSR‐E 89 GHz data. Retrieved compare within 0.5 m with few ULS data available in Strait. The mean, minimum, maximum observed export amounts 217, 92, 420 km 3 /month, respectively. In comparison former during 1990s our slightly smaller (−33 /month) but natural variability no significant change total amount can be observed.
