| Popis: | 100 Owing to the satellite regular scanning and large-area coverage, a red tide index derived from OrbView-2/ SeaWiFS band 2 data is used in this study to detect the red tide events in the sea around the China coast. The official China ocean disaster report is the main source to be compared with the satellite data. It is found that the red tide could be seen from June to August in Bohai Sea, from April to August in East China Sea, and from February to July in South China Sea. The results match well with the statistics of the previous studies. The satellite-derived red tide index image could also be used to detect the distribution of the red tide area along the China adjacent seas with different time scale from daily, weekly, monthly, and even inter-annual. This is hardly described clearly by the record of China Ocean disaster official report. |
