Cette thèse a pour objectif principal de mieux appréhender la dynamique spatio-temporelle et verticale de la biomasse phytoplanctonique dans l’océan ouvert. Dans un premier temps, nous avons étudié la variabilité de la relation entre le coefficient de rétrodiffusion particulaire (bbp), un estimateur bio-optique du carbone organique particulaire, et la concentration en chlorophylle a (Chla) à l’échelle globale. Dans les régimes subpolaires, des changements concomitants de Chla et bbp correspondent à des variations de la biomasse du phytoplancton. Au contraire, dans les régimes subtropicaux oligotrophes, un découplage entre les deux variables peut être attribué aux processus de photoacclimation du phytoplancton ou à un changement de l'abondan...
