In July 2024, the International Seabed Authority (ISA) Partnership Fund (PF) approved, under the umbrella of the Women in Deep-Sea Research Project (WIDSR), the project “Women in Blue: training opportunities in ocean science", proposed for funding by CNR-ISMAR to provide advanced training in deep-sea research for women scientists from developing countries. The WOMBlue cruise is ultimately the last step of the “Women in Blue: training opportunities in ocean science” initiative. Participants are engaged in seafloor and sub-seafloor mapping, resource identification, biogeochemistry, seafloor and ocean circulation interactions, water column properties, biological sampling, and work with available onboard technologies and equipment related to deep-sea research. In addition, this oceanographic expedition contributed to a further understanding of the interplay between morphology, tectonics, and magmatism during the initial phases of the opening of the Tyrrhenian back-arc basin, as a follow up of a previous cruise (IFIGENIA 2024, Palmiotto et al., 2024), in an area completely unmapped from the point of view of marine data.
