Dear all,

I'm trying to quantify seasonal variability in seawater δ18O as a function of geographical location and depth. I'm aware of the Global Seawater Oxygen-18 Database (https://data.giss.nasa.gov/o18data), but as far as I can tell it provides "only" annual average δ18O values as a gridded dataset.

Do you know of any relevant publications or databases that I should look at?

As always, thanks for your help.

- Mathieu
