The paper discusses a physical model, obtained with the aid of statistical analyses, of the relationships between the sun-induced chlorophyll a fluorescence quantum yield and marine environmental factors. The relationships are based on a large set of empirical data from various ocean regions with basins of different trophicity, at different depths and in different seasons. Underwater spectral radiance and irradiance in the PAR spectral range were used to determine the quantum yield of sun-induced chlorophyll a fluorescence. From a statistical analysis a preliminary mathematical expression was derived to describe the fluorescence quantum yield as a function of the scalar irradiance, basin trophicity and the water temperature in situ. These relationships may be useful for analysing the budget of the light energy absorbed by phytoplankton pigments utilized in chemical and non-chemical quenching.
本文讨论了一个通过统计分析获得的物理模型，该模型描述了太阳诱导的叶绿素a荧光量子产率与海洋环境因素之间的关系。这些关系基于来自不同营养水平、不同深度和不同季节的不同海洋区域的大量经验数据。利用PAR光谱范围内的水下光谱辐射率和辐照度来确定太阳诱导的叶绿素a荧光的量子产率。通过统计分析得出了一个初步的数学表达式，以描述荧光量子产率作为标量辐照度、海域营养水平和现场水温的函数。这些关系可能有助于分析浮游植物色素吸收的用于化学和非化学猝灭的光能收支。
