The THETIDA project approaches safeguarding and protecting Europe’s coastal and underwater cultural heritage from the effects of climate change and natural hazards in a holistic manner that includes risk management, protection and preparedness, as complementary strategies to prevent damages to CH sites, identify and ward off additional threats and promote policy tools for climate neutrality and economic resilience in coastal areas. THETIDA project achieves this goal through the development of a preventive conservation strategy that includes monitoring, risk preparedness and management, for underwater and coastal CH (U&C-CH) sites, identify and ward off additional threats and promote adaptation, reconstruction and other post-disruption strategies to restore normal conditions to the historic area, as well as long-term strategic approaches to adapt to CC and to wield policy tools for economic resilience. In this project, an interdisciplinary team of researchers, experts and practitioners will develop, test and validate an integrated multiple heritage risk assessment and protection system with evidence-based monitoring frameworks, innovative tools and instruments and through participatory processes (Citizens’ Science and Living Labs). The project implementation actions will link the social innovations with cutting-edge technologies (ICT and IoT harmonised tools).

NAUTILOS will fill in existing marine observation and modelling gaps through the development of a new generation of cost-effective sensors and samplers for physical (salinity, temperature), chemical (inorganic carbon, nutrients, oxygen), and biological (phytoplankton, zooplankton, marine mammals) essential ocean variables, in addition to micro-/nano-plastics, to improve our understanding of environmental change and anthropogenic impacts related to aquaculture, fisheries, and marine litter. Newly developed marine technologies will be integrated with different observing platforms and deployed through the use of novel approaches in a broad range of key environmental settings (e.g. from shore to deep-sea deployments) and EU policy-relevant applications: - Fisheries & Aquaculture Observing Systems, - Platforms of Opportunity demonstrations, - Augmented Observing Systems demonstration, - Demonstrations on ARGO Platform, - Animal-borne Instruments. The fundamental aim of the project will be to complement and expand current European observation tools and services, to obtain a collection of data at a much higher spatial resolution and temporal regularity and length than currently available at the European scale, and to further enable and democratise the monitoring of the marine environment to both traditional and non-traditional data users. The principles that underlie the NAUTILOS project will be those of the development, integration, validation and demonstration of new cutting-edge technologies with regards to sensors, interoperability and embedding skills. The development will always be guided by the objectives of scalability, modularity, cost-effectiveness and open-source availability of software and data products produced. NAUTILOS will also provide full and open data feed towards well-established portals and data integrators (EMODnet, CMEMS, JERICO).
