The Application of a Real-Time Biophysical Model of Photoplankton Photoacclimation in the Upper Ocean at Sea

由主要研究人员在Denman和Marra(1986)的光适应模型和Price等人的物理模型的基础上开发的组合生物物理模型。(1986)将被带到海上以实时模式运行，环境物理强迫输入到模式中。实时应用程序将提供海上预测水柱的连续视图，以便可以在适当的深度收集物理和生物(特别是光驯化状态和光合作用速率)样本，以直接测试模型的准确性。模型的一个版本将通过使用各种物理传感器以及专门设计的生物传感器对环境环境所需特征的初步测量进行初始化。第二个版本将每两小时物理重新初始化一次，以确保更准确地预测水柱的瞬时状态。验证数据将包括混合层深度和深度剖面率。在巡航后，将根据模型的后续重新运行进行模型改进，并记录强制，通过考虑模型公式和参数的变化来改进对验证数据的拟合。最终目标是将经过验证的生物物理模型作为一种工具，指导正在开发的光驯化技术和理论的未来现场应用。

A combined biophysical model developed by the principal investigators based on the photoacclimation model of Denman and Marra (1986) and the physical model of Price et al. (1986) will be taken to sea to run in real-time mode with the ambient physical forcing input to the model. The real-time application will provide a continuous view of the predicted water column while at sea, so that physical and biological (especially photoacclimation state and photosynthetic rate) samples can be collected at the appropriate depths to directly test model accuracy. One version of the model will be initialized with preliminary measurements of the required characteristics of the ambient environment using a variety of physical sensors as well as a specially designed biological sensor. A second version will be re-initialized physically every tow hours to ensure a more precise prediction of the instantaneous state of the water column. Validation data will include mixed layer depth and depth profiles rate. After the cruise, model refinements will be developed based on subsequent reruns of the model with recorded forcing to improve fits to the validation data by considering changes in both model formulation and parameterization. The eventual goal is to use the validated biophysical model as a tool to guide future field applications of the developing photoacclimation technology and theory.
