TONGA project



TONGA is a multidisciplinary project dedicated to the study of the control of ocean productivity and carbon export driven by micronutrients from hydrothermal origin. It is based both on a 37-day oceanographic cruise in the Western Tropical South Pacific and modelling work and involves hydrothermal geochemists, physical oceanographers, trace element chemists (ocean and atmosphere), biogeochemists, biologists and modelers.
