The aim of the subproject is to carry out transient simulations with a global state-of-the-art atmosphere-ocean general circulation model in combination with a suite of biogeochemical models to investigate the spatio-temporal variability of oxygen minimum zones (OMZs) during the Holocene (last 10000 years), and over the next few centuries. Focussing on the eastern tropical South Pacific, together with data from paleo reconstructions we shall develop a coherent picture of the internal and external mechanisms driving OMZ variability.

该子项目的目标是利用全球最先进的大气-海洋大气环流模型结合一套生物地球化学模型进行瞬态模拟，以研究全新世（过去10000年）和未来几个世纪期间最低含氧区（OMZ）的时空变化。重点关注东部热带南太平洋，结合古重建数据，我们将绘制出驱动 OMZ 变化的内部和外部机制的连贯图景。
