Team and Institutions PortADa has established four working teams —one for each of the ports under study: Barcelona, Marseille, Buenos Aires, and Havana— comprising experts in maritime and port history working closely with academic staff specialised in digital humanities. Each local team addresses and resolves the specific challenges posed by their respective documentary sources. The technological developments designed to tackle these local issues are shared with the other teams through agile workflows and continuous feedback systems.ental.
