Table 3 Analysis of variance (ANOVA) and post hoc Tukey results testing for significant differences in viral abundance and VPR among layers [epipelagic (EPI), mesopelagic (MESO), and bathypelagic (BATHY)] and oceans [Atlantic (ATL), Indian (IN), and Pacific (PAC)].

Lower panel: ANOVA and post hoc Tukey results testing for significant differences in viral abundances among water masses in the mesopelagic and bathypelagic layers. Only significant values are shown (P < 0.05).
