Abstract
Phosphorus (P) is essential for life, but most of the global surface ocean is P depleted, which can limit marine productivity and affect ecosystem structure. Over recent decades, a wealth of new knowledge has revolutionized our understanding of the marine P cycle. With a revised residence time (~10–20 kyr) that is similar to nitrate and a growing awareness that P transformations are under tight and elaborate microbial control, the classic textbook version of a tectonically slow and biogeochemically simple marine P cycle has become outdated. P moves throughout the world’s oceans with a higher level of complexity than has ever been appreciated before, including a vast, yet poorly understood, P redox cycle. Here, we illustrate an oceanographically integral view of marine P by reviewing recent advances in the coupled cycles of P with carbon, nitrogen and metals in marine systems. Through this lens, P takes on a more dynamic and connected role in marine biogeochemistry than previously acknowledged, which points to unclear yet profound potential consequences for marine ecosystems, particularly under anthropogenic influence.

Extended data
Extended Data Fig. 1 Distribution of dissolved and particulate organic N:P and C:P ratios over the global ocean.
Modeled (colormap) DON to DOP (upper panel) and DOC to DOP ratios (lower panel) at 50 m depth and, observed (coloured circles) PON:POP and POC:POP ratios between the surface and 50 m depth (see Supplementary Information 2). The arrows by the colour scales indicate the Redfield ratios. Note the deviations from the C:N:P Redfield ratio of 106:16:1 (represented in white), with red and blue hues indicating values greater and lower than Redfield, respectively. The sparse particulate data are particularly due to the few POP measurements available.
Extended Data Fig. 2 Metal content of phosphoric ester hydrolases.
Percent of P-monoester (EC 3.1.3) and P-diester hydrolases (EC 3.1.4) that are metal-dependent, illustrating that APs can vary greatly in their metal content. While Mn and Fe occur more often in mono- compared to diesterases, Zn and Co occur more frequently in diesterases over monoesterases.
