2002-2018年长江口邻近海域藻华高发区色素分布图（依据航次情况判定更新周期）

图集绘制的源数据来自2002年至2018年期间在东海长江口邻近海域有害藻华高发区的现场调查航次，基于科研人员经验对数据异常值进行了筛选，采用克里金插值方法对数据进行了插值计算，运用Surfer绘图软件进行再分析数据的绘图，形成中国近海典型海域有害藻华高发区色素图集。

The source data for this atlas is derived from field survey cruises conducted in the high-risk harmful algal bloom (HAB) regions adjacent to the Yangtze River Estuary of the East China Sea between 2002 and 2018. Data outliers were first screened based on the expertise of scientific researchers, followed by interpolation processing on the dataset using the Kriging interpolation method. Finally, the re-analyzed data was visualized with Surfer software, resulting in the pigment atlas of high-risk HAB areas in typical offshore waters of China.
