摘要

利用遥感卫星资料,阐明了日本有明海集中研究区冬季叶绿素-a的出现机制及其局域分布。利用Terra和AQUA MODIS数据导出的叶绿素-a浓度和叶绿素-a浓度真值数据以及2010年冬季至2015年冬季6年的气象资料和潮汐资料进行试验,发现叶绿素-a浓度与潮高变化具有较强的相关性。还发现了海洋风速与叶绿素-a浓度之间的关系。日照时数与叶绿素-a浓度有较高的相关性。此外,还发现有明海域、依沙屋湾海域和熊本近海3个不同海域的叶绿素-a来源不同。

Locality of Chlorophyll-A Distribution in the Intensive Study Area of the Ariake Sea, Japan in Winter Seasons based on Remote Sensing Satellite Data
Mechanism of chlorophyll-a appearance and its locality in the intensive study area of the Ariake Sea, Japan in winter seasons is clarified by using remote sensing satellite data. Through experiments with Terra and AQUA MODIS data derived chlorophyll-a concentration and truth data of chlorophyll-a concentration together with meteorological data and tidal data which are acquired for 6 years (winter 2010 to winter 2015), it is found that strong correlation between the chlorophyll-a concentration and tidal height changes. Also it is found that the relations between ocean wind speed and chlorophyll-a concentration. Meanwhile, there is a relatively high correlation between sunshine duration a day and chlorophyll-a concentration. Furthermore, it is found that there are different sources of chlorophyll-a in the three different sea areas of Ariake Sea area in the back, Isahaya bay area, and Kumamoto offshore area.
