Notes: SW = seawater calculated from Mg, DW = deionized water estimated from Na (see text), HEM = hydrothermal end-member component by difference. * = estimates subject to greater error. † = recalculated from Douville (1999). ‡ = CSIRO data from hydrocasts outside the PACMANUS plume; italics denote data from Mitra et al. (1994) and assumed 87Sr/86Sr.
