Deep-dwelling coccolithophore species abundance is greatly affected by nutricline and thermocline depths.
Groups like the European-based CALMARO citation are monitoring the responses of coccolithophore populations to varying pH’s and working to determine environmentally sound measures of control.
In the Black Sea, the main period of coccolithophore growth occurs after the bulk of the dinoflagellate growth has taken place.
Overall, coccolithophore diversity is low in the Black Sea, and although recent sediments are dominated by E. huxleyi main, Braarudosphaera bigelowii main, Holocene sediments have also been shown to contain Helicopondosphaera and Discolithina species.
Some species like Calcidiscus leptoporus, however, are not affected in this way, while the most abundant coccolithophore species, E. huxleyi is.
The increase in agricultural processes lead to eutrophication of waters and thus, coccolithophore blooms in these high nitrogen and phosphorus, low silicate environments.
