Abstract:
Interstitial water samples from Leg 86 were analyzed for Cl-, SO42-, Ca2+, Mg2+, K+ , Li+ , Sr2+, Mn2+, Si, NO3-, NH4+ , and d18O. The principal findings are as follows. (1) The chloride profiles consistently show a about 1.5% downcore increase to about 40 m sub-bottom depth. This increase is consistent with model profiles generated by considering the effects of variations in seawater salinity resulting from Pleistocene glaciation on pore-water composition. d18O profiles support this model. This agreement of model and observation precludes advection of the pore fluids at rates greater than 1 mm/yr. (2) Ca2+ and Mg2+ gradients are small relative to other Deep Sea Drilling Project sites, likely resulting from low diffusive fluxes through underlying chert horizons. (3) Other constituents exhibit profiles consistent with previous observations.
