GSR's exploration activities in the Clarion Clipperton Zone (CCZ) focus on three major elements: resource assessment, technology and environment, all of which are shown in this 12-minute video covering the company's 2017 Pacific campaign. To verify resource estimates undertaken during GSR's 2014 and 2015 campaigns, nodules were collected using deep-sea dredges and box cores. The technological aspects involved the deployment of 'Patania I', the first tracked vehicle to reach and travel the seafloor at depths of more than 4,500 m. Meanwhile scientist from both GSR and independent research institutions collected baseline data to better understand sites that may be subject to mining in the future and ensure that any such activities only proceed once the environment impact has been judged acceptable by the international community.
