项目摘要

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.

东京大学海洋研究所与圣地亚哥的加州大学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，ORIUT的新Hakuhomaru访问了斯克里普斯研究所，通过举办物理海洋学、渔业海洋学、海洋化学、海洋生物学和海洋生物物理学方面的讲习班，改进了合作研究。研究了两个海岸沙丁鱼资源的波动，并提出了一个生态模型作为研究的结果之一。通过这两个研究所进行的CTD观测和部署在不同深度的中性浮标的跟踪，研究了太平洋的深层环流。就海底磁力计和电位计等海洋地球物理数据进行了数据交流和讨论，以阐明地球表层的全球变化。通过对北太平洋和赤道太平洋的水取样和沉积物捕集器系泊，研究了海洋中营养物、溶解氧和示踪元素的通量以及碳循环。
