After measuring the δ18O of forams, how to apply correction in the δ18O value caused by variations in the global ice volume, which in turn induces a change in the δ18O value of seawater and so also the calcifying foraminifera shells?
Hello Sanjit KUMAR Jena
I suggest you interpolate the data from your preferred ice volume curve (e.g., Waelbroeck et al., 2002; although there are more recent publications) according to your sample ages, extracted from your own age model. After that you can use the ice volume values you got to do the ice volume correction.
A very well explained and detailed article for paleoSSS reconstruction is Data Salinity changes in the western tropical South Atlantic duri...
. For SST values you can either use the Modern Analogue Technique or other proxies like Mg/Ca.Since these reconstructions imply considerable errors, some papers tend not to convert the oxygen residual values to salinity. But it is up to you and your data.
I hope it helps,
Vou te mandar uma tabela que faz isso. Podemos marcar um Zoom pra eu te explicar essa tabela.

Please have a look at this site:

Thank you. I went through your suggestions and it was quite helpful to me. Thanks a lot.
