Volume, freshwater and heat transport through Davis Strait, the northern boundary of the Labrador Basin, are computed using a mooring array deployed for three consecutive years. The net volume, freshwater and heat transports are À2:6 AE 1:0 Sv; À92 AE 34 mSv; 18 AE 17 Â 10 12 W: Both southward and northward volume and freshwater transports are maximum in November. The seasonal variability is dictated by the variability in the main water mass transports: Irminger Sea Water, West Greenland shelf

The southward freshwater transport seasonal amplitude is dominated by the CIL transport rather than the surface meltwater layer. Sea-ice transport through Davis Strait deduced from remote sensing data is equal to 528 km 3 =year which is much smaller than equivalent estimates for Fram Strait. Using these new estimates, we attempt to close the Arctic Ocean volume and freshwater budget. r
