“…The RSD of ice drift is 0.50 which is the largest contributor. Consistent with previous studies, such as Ricker et al (2018) and Bi et al (2018), the ice drift with maximal RSD is more likely to affect variations in sea ice volume flux.…”

“…Therefore, the CMST data which assimilates CS2 and SMOS sea ice thickness and SSMIS sea ice concentration simultaneously have more advantages in calculating sea ice volume and extent export. Ricker et al (2018) and Bi et al (2018), gave their averaged freezing season volume export that are of 1711 km 3 and 1463 km 3 , respectively, based on the CS2 thickness data and different ice drift data over a similar period and outflow gates. Our average estimate of QEX,CMST,CMST (e.g., M2) based on the CMST ice thickness and drift is 1575 km 3 while the QEX, CMST, OSISAF (e.g., M1) derived from CMST thickness and OSI SAF drift is 1599 km 3 in the freezing season.…”

“…Variations of satellite-based Arctic sea ice volume and sea ice export through the Fram Strait have been estimated by numerous studies (Bi et al, 2018;Kwok and Cunningham, 2015;Ricker et al, 2018;Ricker et al, 2017;Spreen et al, 2009). Nevertheless, with respect to the volume flux, the primary focus of these studies are the variations during the winter season (October-April).…”

“…And the variation of the melt season ice volume flux through the Fram Strait still remains a query owing to the fact that sea ice thickness observations are sparse in the melt season, and so does the yearly total amount of ice volume flux. In terms of sea ice volume flux, Ricker et al (2018) and Bi et al (2018) point out that the variation of ice drift plays the major role in determining the annual and interannual ice volume export variability. Due to thermodynamic growth and deformation, the sea ice thickness on the other hand drives the increase in the seasonal cycle of exported volume.…”

Abstract. Sea ice volume export through the Fram Strait plays an important role on the Arctic freshwater and energy redistribution. The combined model and satellite thickness (CMST) data set assimilates CryoSat-2 and Soil Moisture and Ocean Salinity (SMOS) thickness products together with satellite sea ice concentration. The CMST data set closes the gap of stand-alone satellite-derived sea ice thickness in summer and therefore allows us to estimate sea ice volume export during the melt season. In this study, we first validate the CMST data set using field observations, and then estimate the continuous seasonal and interannual variations of Arctic sea ice volume flux through the Fram Strait from September 2010 to December 2016. The results show that seasonal and interannual sea ice volume export vary from −244 (±43) to −973 (±59) km3 and −1974 (±291) to −2491 (±280) km3, respectively. The sea ice volume export reaches its maximum in spring and the mean amount of the melt season ice volume export accounts about one third of the yearly total amount. The minimum monthly sea ice export is −11 km3 in August 2015 and the maximum (−442 km3) appears in March 2011. Seasonal variations of sea ice thickness and drift frequency distributions infer that the thicker ice accompanied with slower ice motion is easier to appear when there is sea ice exporting through the Fram Strait outlet in summer.

“…As an example, in 2007 anomalous wind conditions over the Arctic contributed to a strengthened transpolar drift and increased sea-ice export through the Fram Strait, reducing the amount of multi-year sea ice within the Arctic (Smedsrud et al 2011;Zhang et al 2008). However, Bi et al (2018) found a decrease in the sea-ice volume export of 600 km 3 /year in the period 2011-2014 compared to the periods 1990-1994 and 2003-2008. They attributed this decline first and foremost to changes in sea-ice drift, and to a lesser extent to changes in sea-ice thickness and even less to a decrease in the sea-ice concentration.…”
