Two hydrographic and Δ18O transects across Fram Strait (Aug--Sept 1997, 1998) are used to examine freshwater contributions to the East Greenland Current (EGC). The EGC featured up to ~16% meteoric water in both years, but was made comparatively more saline through the formation of up to ~11 m of sea ice. We derive meteoric water fluxes of ~3680 km3 yr-1 in Aug--Sept 1997, and ~2000 km3 yr-1 in Aug--Sept 1998. The 1997 and 1998 data show a long-term mean sea ice flux through Fram Strait around half the long-term mean meteoric water flux. A 1991 Δ18O section [Bauch et al., 1995> yielded a very similar ratio. Our 1998 section reveals fresh, low-Δ18O water on the East Greenland shelf whose comparatively large volume constitutes a potentially significant contribution to the total freshwater flux through Fram Strait. Such fluxes are important to the regional and global thermohaline circulation; we suggest that efforts towards monitoring both the EGC and East Greenland shelf waters are thus required. ¿ 2001 American Geophysical Union
