海洋对人类而言是个巨大的物质生产工厂,又是净化槽。通过河流与大气,由大陆运到海洋的物质,经过多种多样的过程后,不久又在海洋中变成了沉积物。一种物质沉积在海洋中的平均长度,因该物质的物种和存在状态的差异而有很大的不同。已变残沉积物的物质,由于沉积物中的化学变化,也有再次回到海洋中来的。对这样以海洋为中心的物质运动经路和消长关系的研究〔全球海洋消长研究(global ocean blux stady简称GOFS),是由美国发起的旨在究明与海洋中的物质循环相关联的物理的、化学的、生物的过程的一项计划,该计划第一次专题讨论会已于1984年9月在华盛顿召开——译者),在掌握围绕海
The sea is a huge material production plant for mankind and a purification trough. Through the rivers and the atmosphere, the matter transported from the mainland to the oceans, after a variety of processes, soon became a sediment in the oceans. The average length of a substance deposited in the ocean varies greatly depending on the species and state of existence of the substance. Substances that have become disintegrated sediments, due to the chemical changes in the sediments, have also returned to the ocean again. The study of the relationship between ocean-centric movement and the growth and decline of the material [global ocean blux stady (GOFS)) was initiated by the United States to clarify the physics associated with the material cycle in the oceans, A plan for a chemical and biological process, the first Symposium of which was held in Washington in September 1984 - translator)
