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 km³yr−1 in Aug‐Sept 1997, and ∼2000 km³yr−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.
