Short summary

We present a new Quaternary S-isotope record of seawater sulfate. We find that the steady decline in the seawater S-isotope ratios stops around 700ka, which we relate to the termination of the massive net “sediment offloading”and a new equilibrium state between shelf erosion during sea level lowstands and sediment resupply during sea level highstands.
