Water & Material Circulation in the Japan and East China Sea

“日本海和东海的水和物质循环”项目是由日本文部科学省支持的国际合作研究项目。它通常被称为CREAMS项目，并被认为是海委会/西太平洋分委会“海洋动力学和气候II”的重要活动之一。该计划的目标是澄清边缘海的环流，研究相关的基本过程，并建立可靠的物理，化学和生物研究的数值模式。事实上，在夏季（1993年、1994年）和冬季（1995年）在俄罗斯研究船上对日本海进行了全流域的联合观测。观测工作包括对海底进行精确的温深测量、进行水取样以进行化学研究、释放表面漂流物、部署带有流速计和沉积物收集器的系泊设备以及通过专门设计的拖曳车进行物理和化学测量。在过去两个项目年内，收集了卫星红外线图像和高度计数据，以支持观测结果。在福冈（1994年）和首尔（1995年）举行的国际（公开）研讨会上，结合数值模式、数据分析、实验室试验和理论的结果，对这些新的数据集进行了讨论。

The Project "Water and Material Circulation in the Japan and East Chaina Seas" is an international cooperation research program supported by the Ministry of Education, Science and Culture, Japan. It is generally Kwown as CREAMS project and recognized as one of the important activities of IOC/WESTPAC 'Ocean Dynamics and Climate II'. The goal of the program is to clarify the circulation of the marginal seas, to study associated basic processes and to contrust reliable numerical models for physical, chemical and biological studies.A feature of the project is its intensive effort to collect new date sets. In fact, basin-wide joint observations of the Japan Sea were carried out in summer (1993,1994) and in winter (1995) on board Russian research vessels. The observaional work included precise CTD to the bottom, water sampling for chemical study, release of surface drifters, deployment of moorings with current meters and sediment traps and physical and chemical measurments by means of a specially designed towing vehicle. To back up the observations, satellite infra-red images and altimeter date were colleced during the past two project years. Those new date sets were discussed in relation to results of numerical models, date analyzes, laboratory experiments and theory at international (open) symposium in Fukuoka (1994) and Seoul (1995).
