The water is too deep for storms to stir up nutrients from the bottom and there isn’t upwelling. Primary productivity in tropical oceans is limited by the amount of nutrients available. The Southern Oscillation in surface circulation and climate over the –60 tropical Atlantic, Eastern Pacific, and Indian Oceans as captured by cluster analysis. polar latitudes (e.g., 80° of latitude). 80% of the world's photosynthesis takes place in the ocean. While such measurements have contributed to a remarkable extent to the knowledge of plankton productivity, the limitations of the method should not be overlooked. The total aboveground biomass (dry weight of organic matter in an area) for temperate deciduous forests is typically 150 to 300 metric tons per hectare; values for temperate broad-leaved forests are generally higher, and those for sclerophyllous forests are lower.

Paradoxically, the warm tropical oceans where coral reefs are found are generally very low in nutrients, raising questions about how these rich and diverse ecosystems can be so productive in the oceans where they live. The tropical Pacific basin is responsible for roughly 20% (9–14 Pg C yr-1) of global ocean productivity (see Supplementary Information) and has a prominent function in air–sea CO 2 exchange. In oceans productivity is generally limitated by nitrogen. Upwellingzones bring nutrient-rich deep water to the surface, fueling primary productivity.
