Fram Strait sea ice export variability over the last 80 years Smedsrud, Lars Henrik; Halvorsen, Mari H; Kloster, Kjell https://doi.pangaea.de/10.1594/PANGAEA.868944

Short summary

Export of Arctic sea ice area southwards through the Fram Strait from 1935 to 2014 is calculated based on satellite radar images and surface pressure observations. The annual mean export is 880 000 km², representing 10 % of the Arctic sea ice area. In recent years the export has been above 1 million km², and there are positive trends over the last 30 years. Increased ice export during spring and summer contributes to more open water in September, and this correlations has increased over time.
