Their impact on the carbon cycle is however highly dependent on the abundance and type of coccolithophore present - as calcification, growth and sinking rates vary widely between species. Nonetheless, representation of coccolithophores in biogeochemical models is usually limited to single functional types. Trait based approaches - which model traits such as size instead of individual species - offer a promising avenue for better representation of coccolithophores in models. Yet, it is not clear which coccolithophore traits are most appropriate or how they can be represented numerically.</span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);" class=""><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; background-color: rgba(255, 255, 255, 0);" class=""><span class="Apple-tab-span" style="white-space:pre"> </span>Here I explore coccolithophore traits using an integrated approach combining modelling and laboratory experiments - with a specific focus on the coccolithophore life cycle.
