Monitoring of marine primary production in the marginal seas

利用现场传感器和海洋颜色遥感对太平洋东北亚边缘海的初级生产力进行了生物光学监测。通过连续测量天然荧光进行原位监测，改进的算法与碳吸收量有较好的一致性。利用1999年至2000年在日本海和中国东海进行的巡航期间获得的生物光学参数，对从遥感信息估计初级生产力的区域算法进行了研究。Pbopt和叶绿素a被认为是最关键的参数在这两个领域。虽然Kameda-Ishizaka算法在验证中获得了最佳性能，但平均而言，估计值的变化系数为2，需要进一步改进。1996年至2002年的叶绿素a和初级生产力的时间序列观测使用OCTS和Sea WiFS获得的数据显示，在日本海春季水华的时间和幅度的逐年变化。与日本海相比，东海的情况2水问题全年都很明显。

Bio-optical monitoring of primary production using in situ sensors and ocean color remote sensing was examined for Northeast Asian marginal seas of the Pacific Ocean. In situ monitoring was conducted by the continuous measurement of natural fluorescence with which improved algorithm resulted in a satisfactory accordance with carbon uptake. Regional algorithms for estimating primary production from remotely sensed information were examined with published algorithms using bio-optical parameters obtained during cruised conducted between 1999 and 2000 in Japan Sea and the East China Sea. Pbopt and chlorophyll a were found to be most critical parameters in both areas. While Kameda-Ishizaka algorithm yielded best performance in the validation, estimates varied in the factor of 2, on average, posing requirement of further improvement. Time series observations of chlorophyll a and primary production from 1996 to 2002 using data obtained by both OCTS and Sea WiFS revealed year-to-year variations in both timing and magnitude of spring bloom in Japan Sea. In contrast to Japan Sea, case 2 water issue was distinct throughout the year in the East China Sea.
