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.
We present a new Quaternary S-isotope record of seawater sulfate. We
