自1993年至今,美国地质调查局的科学家及其合作伙伴在美国西海岸的Monterey海底峡谷进行了针对现代浊流过程的一系列基础性研究,并成功地在世界上首次实地测量到高精度浊流流速及粒度参数。近20年来的数据和知识积累为解释海底峡谷内沉积物和其他颗粒物质输运的机理,以及浊流在维持深海峡谷中生机勃勃的生态系统所起的重要作用提供了直接依据。通过展示把海底观测应用于海洋沉积动力学研究过程中的成果、经验、教训,以及介绍目前还在讨论中的研究计划,以期达到以下宏观论点:在海洋科学里,只有科学与技术不脱节的科研团队才有希望获得成果和突破。
Since 1993, the Geological Survey of USA scientists and their partners conducted a series of fundamental studies on modern turbidity processes in the submarine canyon of the Monterey, on the west coast of the United States, and succeeded in making the world’s first real-world measurement of high-precision turbidity currents Flow rate and particle size parameters. The accumulation of data and knowledge over the last two decades has provided a direct basis for explaining the mechanism of sediment and other particulate matter transport within the submarine canyon and the important role played by turbidity in maintaining a viable ecosystem in the deep canyon. By demonstrating the results, experiences and lessons learned from the application of seafloor observations to the study of marine sediment dynamics, and introducing the research programs currently under discussion, the following macroscopic arguments can be reached: In the marine sciences, only science and technology are not disconnected Research teams have the hope of achieving results and breakthroughs.
