1 Introduction
Phytoplankton are responsible for approximately 40–50 % of the total primary
production on Earth. They contribute to controlling the total CO 2 concentration
and pH of the ocean, which together with physical processes (e.g. solar energy
input, sea–air heat exchanges, upwelling of subsurface waters and mixed layer
thickness) dictates the air-to-sea CO 2 gas exchanges (Longhurst et al. 1995; Field
et al. 1998; Takahashi et al. 2002; Falkowski et al. 2004). The global net primary
production from phytoplankton is 45–50 Gt C year −1 , whilst from land plants
