Abstract
Measured concentrations of dissolved oxygen, phosphate, silicate, total alkalinity and calculated total CO2 in a section between 121° E and 125° E across the Kuroshio near 22° N off Taiwan and the geostrophic velocity were used to estimate the gross transport of oxygen, nutrients and carbonates.
The flux of dissolved oxygen is 6.7×106 mol/s northward and 0.9×106 mol/s southward. The net flux equals 5.8×106 mol/s down-stream. The northward flux of phosphate is 22.6×103 mol/s; the southward flux is 1.4×103 mol/s. The net phosphate flux is 21.2×103 mol/s northward. The flux of silicate is 967×103 northward and 59×103 mol/s southward; the net transport is 908×103 mol/s down-stream. The flux of alkalinity is 75.5×106 mol/s northward, and 10.8×106 mol/s southward, the net flux is 64.7×106 mol/s northward. For total CO2 the transport is 73.4×106 mol/s northward and 10.8×106 mol/s southward, or a net transport of 62.6×106 mol/s horthward.
