Ocean Dynamics in Relation to Global Change

东京大学海洋研究所与加州大学圣地亚哥分校斯克里普斯海洋学研究所就与全球变化有关的海洋动力学问题进行了合作研究。1986年，两所大学同意进行海洋科学研究。1989年11月，海洋资源研究所的新白本原访问了斯克里普斯研究所，并通过在物理海洋学、渔业海洋学、海洋化学、海洋生物学和海洋地球物理学方面举行的讲习班改进了合作研究。本文研究了两岸沙丁鱼资源的波动情况，并建立了一个生态模型。两个研究所进行的CTD观测和在不同深度部署的中性浮标的跟踪，研究了太平洋的深层环流。对海底磁力计和电势计等海洋地球物理资料进行了数据交换和讨论，以阐明地球圈的全球变化，通过取样和北太平洋和赤道太平洋沉积物圈层的系泊，研究了海洋中营养物、溶解氧和示踪元素的通量以及海洋中的碳循环。

The Ocean Research Institute, University of Tokyo, has conducted cooperative studies between the Scripps Institution of Oceanography, University of California at San Diego on the subject of ocean dynamics relating global change. Both universities agreed to carry out the studies in marine sciences in 1986. In November 1989, the new Hakuhomaru of the ORIUT visited Scripps Institution and refinements of the cooperative studies were made through workshops held in physical oceanography, fisheries oceanography, marine chemistry, 'Marine biology and marine geophysics. Fluctuations of sardine resources at both coasts are investigated and an ecological model is presented as one of the results of the studies. Deep circulation in, the Pacific Ocean are studied by the CTD observations carried out by both institutes and by trackings of neutral floats deployed at various depths. Data exchange and discussions were made on the marine geophysical data such as the ocean bottom magnetometers and the electro-potential meters in order to elucidate the global change in the geospere Ocean fluxes of nutrients, dissolved oxygen, and tracer elements and carbon cycles in the ocean are studied by sampling water and by moorings of sederment traps in the North and Equatorial Pacific Ocean.
