Diatoms (image seen below) Oceanic phytoplankton is the primary food source, directly or indirectly, of nearly all sea organisms. Composed of groups with siliceous skeletons, such as diatoms, dinoflagellates, and coccolithophores, phytoplankton varies seasonally in amount, increasing in spring and fall with favourable light, temperature, and minerals. El Niño events influence weather patterns beyond the Pacific; in the eastern Indian Ocean around Indonesia, for example, phytoplankton productivity increases during El Niño. Productivity in the Gulf of Mexico and the western sub-tropical Atlantic has increased during El Niño events in the past decade, probably because increased rainfall and runoff delivered more nutrients than usual.
