Summary:The Sr concentration and isotopic composition of the world's major rivers have been measured, doubling the fluvial Sr isotope data base. This has produced a more accurate estimate for the 87Sr/86Sr ratio of global runoff of 0.7119, higher than previously calculated. Data on the Sr concentration and 87Sr/86Sr ratio of oceanic hydrothermal vent waters from a variety of environments have been combined with previously published riverine data and values for the diagenetic benthic flux of Sr from deep-sea sediments to obtain a contemporary oceanic Sr budget. The results of steady-state calculations give a best estimate for the flux of sea-water through high T ridge crest hydrothermal systems which is substantially higher than recent estimates. [R.E.S.]
