François Charlet, currently exploration manager at Global Sea Mineral Resources NV, oversees the offshore campaigns related to resource definition and environmental baseline studies. After studying marine geology and sedimentology in France where he obtained his master’s degree from the University of Lille I, Mr. Charlet began his professional career in Belgium, as a research assistant at the Renard Center of Marine Geology, Ghent University. In 2005, he joined the DEME-Group as marine geologist, and worked mainly on soil investigations worldwide, as part of foreign dredging and environmental projects. In 2013, he joined Global Sea Mineral Resources NV as an exploration manager to lead exploration and research expeditions at sea. Up to now, he has led and participated in eight offshore campaigns in the Clarion-Clipperton Zone, Pacific Ocean, and Cook Islands, EEZ.

Dr. Ann Vanreusel studied biology at Hasselt University and completed her licentiate studies at the University of Ghent, Belgium. She joined the research group in marine biology and started a PhD on the ecology of meiofauna in coastal environments. As a post-doctoral researcher at the University of Ghent, she focused on deep-sea research, especially in the context of various European projects. Dr. Vanreusel has more than 250 scientific publications in this field and was a principal scientist during various research campaigns on the European margins, from Portugal to Ireland. Dr. Vanreusel is a full professor at the University of Ghent, where she teaches and co-organizes the inter-university course in marine and lacustrine sciences and management.

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.
