项目摘要

High concentrations of technologically critical elements (such as Te, cobalt, REEs, Nb, Pt, W, Bi, Ni, Mn & Ti) occur throughout the global ocean basins where they are incorporated into thick crusts of ferromanganese oxide (otherwise known as Fe-Mn crusts). These crusts have attracted particularly interest because they are very rich in rare elements such as cobalt, tellurium and selenium. These elements are in short supply but they are critical to emerging new technologies including renewable energy and the 'green' economy. Recent estimates of the potential global tonnage of these metal rich crusts suggest about 200 billion tonnes exists on the seafloor. International interest is growing with China and Japan applying for mining licenses from the United Nations International Seabed Authority. Hence the need to address concerns about the sustainability of these crusts as a resource and their potential environmental impacts if exploited.This proposal aims to establish a consortium of geological, biological and oceanographic researchers and industry specialists that will identify what processes control the formation, distribution, abundance and concentration of metal-rich crusts on the deep seafloor. By bringing together a team of specialists, we will also address technical issues surrounding the exploration of these crusts and environmental issues related to their exploitation.

高浓度的技术关键元素（例如碲、钴、稀土元素、铌、铂、钨、铋、镍、锰和钛）遍布全球海洋盆地，并融入厚厚的铁锰氧化物结壳（也称为铁锰结壳）中。这些地壳引起了人们特别的兴趣，因为它们富含钴、碲和硒等稀有元素。这些元素供应短缺，但它们对于包括可再生能源和“绿色”经济在内的新兴新技术至关重要。最近对这些富含金属结壳的全球潜在吨位的估计表明，海底存在约 2000 亿吨。随着中国和日本向联合国国际海底管理局申请采矿许可证，国际兴趣日益浓厚。因此，需要解决对这些结壳作为资源的可持续性及其开发后潜在环境影响的担忧。该提案旨在建立一个由地质、生物和海洋学研究人员以及行业专家组成的联盟，以确定哪些过程控制着深海海底富含金属结壳的形成、分布、丰度和浓度。通过聚集专家团队，我们还将解决围绕这些结壳勘探的技术问题以及与其开采相关的环境问题。
