Water samples were obtained with Niskin bottles attached to a CTD profiler that included sensors for conductivity, temperature, oxygen, fluorescence and turbidity. About 12L of seawater were sequentially filtered through a 20m nylon mesh, followed by a 3m and 0.2m polycarbonate filters of 142mm diameter (Isopore, Millipore). Only the picoplankton size-fraction (0.2-3 m) was used for sequencing. DNA was extracted using a standard phenol-chloroform protocol (Massana, et al. 1997). The V4 region of the 18S (~380 bp) was amplified with the primers TAReuk454FWD1 and TAReukREV3 (Stoeck, et al. 2010). Duarte CM. 2015.
