Dear Bill,

We have two papers:

Punning, J.-M., Martma, T., Kessel, H., Vaikmäe, R., 1988. The isotopic
composition of oxygen and carbon in the subfossil mollusc shells of the
Baltic Sea as an indicator of palaeosalinity. Boreas 17, 27-31.

Punning, J.-M., Vaikmäe, R., Mäekivi, S., 1991. Oxygen-18 Variations in the
Baltic Sea. Nucl. Geophys. 5, No.4, 529-539.

I hope this helps a bit.
