Abstract
The study's major goal was to identify the most significant coccoliths based on foraminiferal species and fragment abundances, oxygen isotope ratios, and calculated temperatures. The degree of preservation of coccoliths and foraminifera indicates that the carbonate lysocline is between 3500 and 4000 m. The distribution of forty-four coccolithophore species in one hundred deep-sea core-tops from the southwest Indian Ocean is used. Gephyrocapsa oceanica has the strongest relationship with the foraminiferal fragments and carbonate. Calcidiscus leptoporus has the strongest influence on oxygen isotope and derived temperature. The findings could be useful in advancing paleoceanographic research.
