本文概述了过去海洋矿物勘探，并与目前的战略进行了比较。目前的重点是放在专有经济区（EEZs）的勘探项目上，特别是沿海和近海区域。尽管在大洋中脊的金属结核和块状硫化物仍然具有重要意义。文中介绍了一科通过γ射线频谱连续测量分析海洋底板的一种相当新的辐射矿物勘探工具，提出了在丹麦水域用原型探头收集的初步数据。 This article outlines past marine mineral exploration and compares it with current strategies. The current focus is on exploration projects in the EEZs, especially in the coastal and offshore areas. Although metallic nodules and massive sulphides in the mid-oceanic ridges remain significant. In this paper, a fairly new radiometric mineral prospecting tool for the continuous analysis of the ocean floor by gamma-ray spectrometry is introduced, and preliminary data collected with prototype probes in Danish waters are presented.
