(Table S1) Nutrients, Chl a concentration according to size classes as well as assimilation rates in the South Indian Ocean and the French Southern and Antarctic Lands, Marion Dufresne cruise MD206

Nutrients were collected and analysed in the lab. TChla. was calculated from diagnostic pigments (Vidussi et al. 2001) and size classes were calculated using multiple regression analysis after Uitz et al. (2006). Incubations for Carbon fixation, Ammonium assimilation and Nitrate assimilation were done in triplicates in two different incbation bins.
