Coccolith Sr/Ca is a robust temperature and growth rate indicator that withstands dynamic microbial interactions.

ABSTRACT: Coccolithophores are a diverse group of calcifying microalgae that have left a prominent fossil record on Earth. Various coccolithophore relics, both organic and inorganic, serve as proxies for reconstruction of past oceanic conditions. Emiliania huxleyi is the most widely distributed representative of the coccolithophores in modern oceans and is known to engage in dynamic interactions with bacteria. Algal-bacterial interactions influence various aspects of algal physiology and alter algal alkenone unsaturation (U^K' ₃₇ ), a frequently used organic coccolithophore-derived paleo-temperature proxy. Whether algal-bacterial interactions influence inorganic coccolithophore-derived paleo-proxies is yet unknown. A commonly used inorganic proxy for past productivity and sea su
