Observation of manganese nodules and manganese coated coral in the West Northern Atlantic ocean

Photography has become an integral part of submarine geological and biological investigations of the ocean bottom. The underwater cameras used to make these photographs were designed by Harold Edgerton. The pictures were taken from 1960 to 1962, from ships of the Woods Hole Oceanographic Institution. They show that life occurs even in the deepest trenches, and that sedimentary and biological processes in deep water do not differ in kind from those in shallow water.

摄影已成为海底地质与生物调查不可或缺的组成部分。本次拍摄所用的水下相机由哈罗德·埃杰顿（Harold Edgerton）设计。这批照片拍摄于1960年至1962年间，由伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution）的科考船完成拍摄。影像资料表明，即便在最深的海沟中也存在生命活动，且深水环境中的沉积作用与生物过程，在本质上与浅水环境并无差异。
