The team of geologists went aboard the Sarmiento de Gamboa, an oceanographic vessel of the CSIC, and used an advanced remotely operated vehicle (ROV) to survey the waters at depths around 2.5km (1.5 miles) for a better understanding of the region’s volcanic activity. The dive was part of the team’s Atlantis project which aims to understand underwater volcanic and hydrothermal activity in the region (Picture: IGME-CSIC)
