TRANSPORT OF OXYGEN,NUTRIENTS AND CARBONATES BY THE KUROSHIO CURRENT

Measured concentrations of dissolved oxygen,phosphate,silicate,total alkalinity and calculated totalCO2 in a section between 121°E and 125°E across the Kuroshio near 22°N off Taiwan and thegeostrophic 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 netflux equals 5.8×106 mol/s down-stream.The northward flux of phosphate is 22.6×103 mol/s;the south-ward flux is 1.4×103 mol/s.The net phosphate flux is 21.2×103 mol/s northward.The flux of silicateis 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 is64.7×106 mol/s northward.For total CO2 the transport is 73.4×106 mol/s northward and 10.8×106 mol/ssouthward,or a net transport of 62.6×106 mol/s northward.

Measured concentrations of dissolved oxygen, phosphate, silicate, total alkalinity and calculated total CO, 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 CO, the transport is 73.4 × 106 mol/s northward and 10.8 × 106 mol/s southward, or a net transport of 62.6×10~6 mol/s northward.
