Mean interstitial salinities in sediments from a salt marsh decrease with depth from a value near the sediment‐water interface which reflects near maxima of bottom water salinities. Density gradient induced exchange across the interface controls pore water salinities near the sediment surface while response of the fresh groundwater table beneath the marsh to varying hydrostatic pressures over the marsh controls interstitial salinities at depth.
