Prediction of the optical properties of the upper ocean is of central importance in oceanography. These properties regulate the penetration of visible radiation with ramifications for both physical and biological oceanographic processes. Solar radiation absorbed in the upper layers heats and stabilizes the ocean; as a result, variability in the rate of attenuation of visible radiation plays a strong role in the upper ocean thermal structure and dynamics. Absorbed radiation is responsible for driving the photosynthetic process on which life in the sea depends. For applied interests, the attenuation of visible wavelengths dictates the effective transmission from point and diffuse sources either at the sea surface, or at depth. The goals of my research program are to examine both the sources of variability in ocean optical properties, and to evaluate the effect of this variability on both oceanic biogeochemical cycles and the physical climate interactions:

上海的光学性质的预测在海洋学中至关重要。这些特性调节可见光辐射的渗透以及对物理和生物海洋学过程的影响。在上层吸收的太阳辐射可加热并稳定海洋。结果，可见辐射衰减率的变化在上海热结构和动力学中起着重要作用。吸收的辐射负责推动海中生命所依赖的光合作用过程。为了应用的兴趣，可见波长的衰减决定了从点和弥漫源的有效传输，要么在海面或深度处。我的研究计划的目标是检查海洋光学特性的可变性来源，并评估这种变异性对海洋生物地球化学周期和物理气候相互作用的影响：
