The small and large plastidic eukaryotes were identified and counted by flow cytometry triggered on chlorophyll autofluorescence, so aplastidic protists are not counted here.

^aAd = Adriatic Sea, Ar = Arabian Sea, IO-Indian Ocean, M = Addu Atoll, Maldives, s.e. = standard error, S = surface (<3 m), sample depths greater than 50 m were targeted at the subsurface chlorophyll maximum, nd = not detected.
