The Horizon 2020 project NEANIAS, which began at the end of 2019 with the goal of developing prototypes of innovative services in the EOSC context, particularly for the submarine, atmospheric, and space research sectors, has been completed. The project's Italian scientific partners are GARR, INAF, and UNIMIB, while ALTEC (an ASI subsidiary) and MEEO participated as SMEs (small and medium-sized companies).
