[Details of award-winning research]
The Western North Pacific Ocean by our university's training ship "Shioji Maru"141.5^oEline(27.0~36.5N) observations, the dissolved organic nitrogen (DON), dissolved organic phosphorus (DOP), nitrate + nitrite, and phosphate distributions in most ocean areas.DON,DOPThe concentration is higher in summer than in winter, and nitrate+Nitrite and phosphate concentrations were lower in summer than in winter. The difference in concentrations between summer and winter was nitrate at higher latitudes.+Nitrites and phosphatesDON,DOPAt lower latitudes,DON,DOPwas equal to or greater than that of nitrate + nitrite and phosphate, respectively.DON,DOPIt was shown for the first time that the production and accumulation processes of cereals differ depending on latitude.
