| Research Abstract |
The sinking fluxes of particulate organic carbon (POC) in the mesopelagic layer were estimated from the natural radioisotope, <210>^Po in the several seasons in the subarctic and subtropical gyres of the western North Pacific Ocean. The annual mean and seasonal variation of POC fluxes in the subarctic gyre were larger than those in the subtropical gyre. It was considered that the biological sinking capacity of carbon in the subarctic gyre was larger than that in the subtropical gyre.
