Maximum quantum yield of the coral Pocillopora was significantly higher at Malden than at the southern islands, which did not differ from each other Fig 3H and S3 Table. A positive photosynthetic pigment-nutrient relationship has been demonstrated in a suite of photosynthetic taxa and across a range of environmental conditions. However, our measurements of coral and algal metabolism did not show a strong pattern of enhancement across the SLI, except in the CCA, Porolithon. At all islands, we collected similar sized fragments of the branching coral Pocillopora meandrina , the plating coral Montipora aequituberculata , and the crustose coralline alga CCA Porolithon sp. Monthly mean chl a data were generated for each island and averaged over the period of September—December to provide an integrated estimate of surface-ocean primary production around each island over the period of the cruise. Indications from photosynthetic components that iron is a limiting nutrient in primary producers on coral reefs. Effects of nitrogen and seawater flow-rate on the growth and biochemical composition of Gracilaria foliifera var.

The nutrient input from upwelling supports high levels of primary production in equatorial Pacific surface waters, as evidenced by increased surface-ocean productivity closer to the equator [ 10 , 21 , 35 ].
