On large outflows of Arctic sea ice into the Barents Sea
Winter outflows of Arctic sea ice into the Barents Sea are estimated using a 10-year record of satellite ice motion and thickness. The mean winter volume export through the Svalbard/Franz Josef Land passage is 40 km(3), and ranges from - 280 km(3) to 340 km(3). A large outflow in 2003 is preconditio...

Winter outflows of Arctic sea ice into the Barents Sea are estimated using a 10-year record of satellite ice motion and thickness. The mean winter volume export through the Svalbard/Franz Josef Land passage is 40 km(3), and ranges from - 280 km(3) to 340 km(3). A large outflow in 2003 is preconditioned by an unusually high concentration of thick perennial ice over the Nansen Basin at the end of the 2002 summer. With a deep atmospheric low situated over the eastern Barents Sea in winter, the result is an increased export of Arctic ice. The Oct-Mar ice area flux, at 110 x 10(3) km(2), is not only unusual in magnitude but also remarkable in that > 70% of the area is multiyear ice; the ice volume flux at similar to 340 km(3) is almost one-fifth of the ice flux through the Fram Strait.
