Is one clearly more important than the others and, if so, on what timescales? On page 525 of this issue Tyrrell makes a strong case that it is phosphorus, in the form of dissolved phosphate (PO_4~(3-)), that is the ocean's 'ultimate limiting nutrient'.J. R. Toggweiler...

The Taiwan Strait (TS) directly connects two of the richest fishing grounds in the world - the East China Sea (ECS) and the South China Sea (SCS). Carbon and nutrient supplies are essential for primary production and the Yangtze River is an important source for the ECS. However the ECS ...

The complex biological processes that drive primary production and foraging behavior of upper-level predators in the region are controlled largely by the dramatic bathymetry, hydrography, and biophysical characteristics of the numerous Aleutian passes, where heat exchange, nutrient mixing, and transport ...

The results showed that phosphorus was the lmiting nutrient; and that the optimal N: P ratio of the fertilizers was 7.25 - 7.54 (mean of 7.37), which was significantly lower than the ratio measured in the water, as phosphorus deposited is easily absorbed by sediments and is excessively up...
1) The early–middle Ediacaran ocean was characterized by N Mo colimitation of primary production on a geological timescale that is different from the P limitation on long-term primary production in the modern ocean. 2) A shift in the ultimate limiting nutrient from N and Mo to P likely ...
