The joint hydrographic and geochemical tracer study of the tropical oceans with focus on the eastern tropical South Pacific will be continued to investigate trends of the dissolved oxygen and nutrient distribution over the past 50 years and the advection-dependent factors driving nutrient utilization. Foci will be the linkage between oxygen and nutrient variability and climatic signals, as well as final model-data comparisons, and the factors controlling nitrogen and silicon utilisation in seawater of the eastern tropical Pacific oxygen minimum zone, which will be tackled through a mesocosm experiment and by direct comparison between nutrient utilization and micronutrient distributions in the water column.

将继续对热带海洋进行水文和地球化学联合示踪研究，重点放在热带南太平洋东部，以调查过去50年来溶解氧和营养物质分布的趋势以及驱动营养物质利用的与平流有关的因素。重点将是氧和营养变异性与气候信号之间的联系，以及最后的模型数据比较，以及控制东热带太平洋氧气最低地带海水中氮和硅利用的因素，这将通过中观实验和营养利用与水柱中微营养素分布之间的直接比较来解决。
