PRECISION IMPROVEMENT OF THE OCEAN ECOSYSTEM MODEL THROUGH DIRECT MEASUREMENTS OF DYNAMICAL PROCESSES AT THE AIR-SEA INTERFACE

研制了一种多传感器浮标，即配有GPS波浪传感器和水质探空仪的漂船，通过主要由风浪引起的海气界面过程，直接观测风的变化对上层海洋营养物质和浮游植物垂直分布的影响。多传感器浮标连续获取的上层生态系统表层和次表层的原位数据，有效地促进了低营养层生态系统模型的验证和界面通量和混合层模型方案的修改，从而有助于提高生态系统模型的精度。

A multi-sensor buoy, a drifter attached with a GPS wave-sensor and water-quality sondes, was developed to observe directly the impacts of wind variation on the vertical distributions of nutrients and phytoplankton in the epipelagic ocean through the air-sea interfacial processes mainly caused by wind waves. In-situ data of the epipelagic ecosystem at the surface and subsurface layers obtained continuously by the multi-sensor buoy promoted effectively validations of the lower-trophic-level ecosystem model and modifications of schemes of the interfacial fluxes and mixed layermodels, consequently contributed to the accuracy improvement of the ecosystem model.
