We use theory and numerical models to understand and simulate the organization of marine phytoplankton populations in the global open ocean. We seek to understand how the physical, chemical and predatory environment shapes the diversity and functionality of the plankton communities, and how the organisms feed back on their environment. Our global simulations helped to motivate targeted observations during theĀ Tara Oceans sampling expedition. We will further develop and use these models to interpret and simulate the basin and global-scale patterns observed in the samples.

The scientific activities of the Tara Oceans expedition, led by EMBL senior scientist Eric Karsenti, present an unprecedented effort that resulted in 35,000 samples containing millions of small organism collected in more than 210 ocean stations, chosen for their climatic significance or biodiversity.
