海洋中“有机碎屑雨”的存在,早已引起国内外学者的重视。生物学家认为它为深海生物提供了食物来源(Harding,1974);化学家则认为它是海洋中物质转移的主要途径(Menzels,1974)。但是长期以来,由于实验技术未能解决,无法进行现场研究,因而这些论断均未得到证实。自70年代以来,沉积物捕捉器的使用(詹滨秋等,1991)开创了这个研究领域的新局面。现在不仅能够研究悬浮体的基本特性,而且可以了解它们在沉降过程中的动态变化。沉积物捕捉器的使用,在我国开始于80年代,主要用于浅海和港湾,
The existence of “organic debris rains” in the oceans has drawn great attention from scholars both at home and abroad. Biologists think it provides a source of food for deep-sea creatures (Harding, 1974), and chemists regard it as the main source of material transfer in the ocean (Menzels, 1974). However, these findings have not been confirmed for a long time due to the inability to conduct field experiments on experimental techniques. Since the 1970s, the use of sediment traps (Zhan Binqiu et al., 1991) has opened the door to new developments in this area of research. Now it is not only possible to study the basic properties of suspensions, but also to understand their dynamic changes during sedimentation. Sediment traps used in our country began in the 1980s, mainly for the shallow sea and harbor,
