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.

开发了一种多传感器浮标，即附有 GPS 波浪传感器和水质探空仪的漂流器，用于通过海气界面过程直接观察风变化对表层海洋营养物和浮游植物垂直分布的影响主要是由风浪引起的。多传感器浮标连续获取的表层和地下层表层生态系统的原位数据有效促进了低营养级生态系统模型的验证以及界面通量和混合层模型方案的修改，从而有助于生态系统模型的准确性提高。
