Arc en Sub will trace the intertwined history of tectonic, magmatic and hydrothermal processes in the Rainbow Massif, a hydrothermal field in the Mid-Atlantic Ridge off the Azores.

From May 5 to June 2 2022, an international team will embark on the ship Pourquoi Pas ? The scientists will explore the massif using the AUV IdefX, the ROV Victor 6000 and a series of BBOBS.

The oceanographic campaign will benefit the understanding of the functioning of submarine hydrothermal systems, natural machines for the transfer of matter and heat between the Earth’s interior and its surface, through the crust.
