Dr. Annemiek Vink is a marine geobiologist working as a manager of a project to explore polymetallic nodules in the German Federal Institute for Geosciences and Natural Resources contract area in the Clarion-Clipperton Zone. Her focus is on collecting adequate environmental baseline data and analyzing the potential impacts of nodule exploitation on faunal communities and ecosystems (e.g., due to nodule removal, sediment plume dispersion and settling). Dr. Vink has participated in several research and exploration cruises into the Clarion-Clipperton Zone since 2013. One of the major aims of the project is to work closely with renowned scientific institutions in Germany and abroad to guarantee professional, scientific input to the exploration project and to provide sampling and data-sharing opportunities to the stakeholder community. This creates effective synergies and focused outputs that are valuable from a science perspective and would also help inform policy and the development of robust regulations related to deep-sea mining and environmental management.
