Drawings of some examples of phytoplankton

normal

Phytoplankton are extremely diverse, ranging from the smallest photosynthesizing cyanobacteria (synechococcus, prochlorococcus), to relatively large silica-encased diatoms, dinoflagellates, green algae, and calcite-armoured coccolithophores (drawings not to scale).

Distribution of marine diatoms

normal

Diatom distributions in the ocean are mapped in red, with images of different types collected at sea and later seen through microscope (inset). Diatoms tend to dominate where nutrients - notably silicate - are plentiful. Their cell walls are primarily composed of silica.

Phytoplankton samples were collected by Ivona Cetinić, NASA GSFC (USRA), during the Schmidt Ocean Institute Sea to Space Particle Investigation and imaged by Luka S̆upraha and Sunc̆ica Bosak.
