We estimate the winter sea ice export through the Fram Strait using ice motion from satellite passive microwave data (IceMotionSPM).  Sea ice motion (October-May) is obtained by tracking the displacement of common features in sequential 85 and 37 HGz brightness temperature fields.  The average winter area flux over the 18-year record (1978-1996) is 670,000 km², ~ 7% of the area of the Arctic Ocean.  The winter area flux ranges from the minimum of  450,000 km² in 1984 to a maximum of 906,000 km² in 1995.  The daily, monthly, and interannual variabilities of the ice area flux are high.   There is upward trend in the ice area flux over the 18 year record.  The average winter volume flux over the winters of October 1990 through May 1995 is 1745 km³ ranging from a low of 1275 Km3 in the 1990 flux to a high of 2791 km³ in 1994.   The sea level pressure gradient across the Fram Strait explains more than 80% of the variance on the ice flux over the 18 year record.
