摘要: Two hydrographic and d18O transects across Fram Strait (Aug-Sept 1997, 1998) are used to examine freshwater contributions the East Greenland Current (EGC). The EGC featured up ?~ 16% meteoric water in both years, but was made comparatively more saline through formation of ?~11 m sea ice. We derive fluxes ?~3680 km3yr-1 Aug-Sept ?~2000 1998. 1997 1998 data show a long-term me~m ice flux around half mean flux. A 1991 section [Bauch et al., 1995] yielded very similar ratio. Our reveals fresh, 1ow-6180 on shelf whose large volume constitutes potentially significant contribution total Strait. Such important regional global thermohaline circulation; we suggest that efforts towards monitoring waters thus required.
