Kiwi scientists uncover stunning underwater insights

Scientists spent three weeks at sea creating a high-definition 3D map of the underwater Colville Ridge. It is estimated to cover 100,000 square kilometres. Scientists found some seafloor rocks in the area that had been hydrothermally altered. This means hot fluids containing dissolved elements such as silica had once passed through them. Often these same fluids dissolved metals that end up accumulating on the seafloor. This indicates that parts of the submerged ridge could be prospective for metallic minerals such as copper and gold. Using a combination of mapping techniques, including solar mapping and magnetism and gravity measurements, Scientists built a detailed picture of the seafloor and its underlying structure
