中文摘要：

我们建议检索吸收的一个简历光的倒置模型浮游植物和有颜色的由岩屑形成的物质(CDM ) 的贡献，以及浮游植物缩放班(PSC ) ，从减水吸收系列的总数。模型基于浮游植物尺寸结构和一个基因算法的三部件的分离。模型表演在二独立数据集上被测试(NASA 简历 -- 光海洋的算法数据集(流浪者) 和北华南海(NSCS ) 数据集) 。在估计并且测量的价值之间的关系是强烈线性的，特别为 CDM (412 ) ，并且 CDM 指数的斜坡(S CDM ) 的根均方差(RMSE ) 是相对低的。下次，倒置模型直接被使用在原处减水总计系列决定了由的吸收一在水下米在在 2008 年 9 月的巡航期间，在海水检索浮游植物尺寸结构。由比较测量并且检索的叶绿素一集中，我们表明了那个总数和尺寸特定的叶绿素一集中能被模型与相对高的精确性检索。最后，我们使用了简历光的倒置模型在一个逆旋风的旋涡在 NSCS 导致的浮游植物尺寸结构调查变化。

英文摘要：

We propose a bio-optical inversion model that retrieves the absorption contributions of phytoplankton and colored detrital matter （CDM）, as well as the phytoplankton size classes （PSCs）, from total minus water absorption spectra. The model is based on three-component separation of phytoplankton size structure and a genetic algorithm. The model performance was tested on two independent datasets （the NASA bio-Optical Marine Algorithm Dataset （NOMAD） and the northern South China Sea （NSCS） dataset）. The relationships between the estimated and measured values were strongly linear, especially for aCDM（412）, and the Root Mean Square Error （RMSE） of the CDM exponential slope （ScDM） was relatively low. Next, the inversion model was directly applied to in-situ total minus water absorption spectra determined by an underwater meter during a cruise in September 2008, to retrieve the phytoplankton size structure in the seawater. By comparing the measured and retrieved chlorophyll a concentrations, we demonstrated that total and size-specific chlorophyll a concentrations could be retrieved by the model with relatively high accuracy. Finally, we applied the bio-optical inversion model to investigate changes in phytoplankton size structure induced by an anti-cyclonic eddy in the NSCS.
