Periodic Report Summary 2 - FIXO3 (Fixed Point Open Ocean Observatories Network)

Project Context and Objectives:
Sustained time-series observations of the ocean’s key properties, from the surface to the deep sea floor are important to understand the role of the oceans and the consequences of the changes currently taking place. Ocean observing infrastructures must be integrated into coherent and complementary networks. The fixed-point open ocean observatories network FixO3 contributes to OceanSITES, the worldwide system of long-term, open-ocean fixed point observatories monitoring the full depth of the ocean water column. The observatories address a wide range of disciplines (biogeochemistry, physics and geology) and environments from the surface to the sea floor.
FixO3 objective is to bring together as one coordinated network all the sustained open ocean multidisciplinary observatories operated by European organisations. The geographical coverage stretches from the Arctic to the Antarctic and throughout the Mediterranean Sea. The programme includes: coordination activities to integrate and harmonise the current procedures and processes; support actions to offer access to observatory infrastructures and open data services and products; joint research activities to innovate and enhance the current capability for multidisciplinary in situ ocean observation.

Project Results:
WP2 TECHNOLOGICAL HARMONISATION: WEB Knowledge based-tool. Handbook on relevant info about sensors and devices tested with information on all the sensors and devices that are used by the observatories within the network. Open source editor software developed for sensor interoperability to facilitate the creation of sensor and sensor platform descriptions using a graphical user interface.
WP3 PROCEDURAL HARMONISATION: The FixO3 Handbook of Best Practices gives recommendations to combine different data towards high quality products. The FixO3 Label is set of criteria for the specifications of open ocean observatories that guarantees the equipment can be fully integrated.
WP4 DATA HARMONISATION: Integration of FixO³ as a data network into the EMODNet physics portal. Propagation of Sensor Web Enablement providing data from six FixO³ observatories. Marine SWE profiles group: development of standardised SensorML and Observations & Measurements profiles for marine observations.
WP5 INNOVATION THROUGH INDUSTRY: Technology Cluster Activities provided detail on the outcomes and feedback from the Industry/Ocean Observatory that meets regularly at Ocean Technology Conferences. The FixO3 IPR Agreement enables commercialisation with industry partners while preserving appropriate IP rights.
WP6 INTERFACE WITH POLICY AND INTERGOVENRMENTAL BODIES: Clear recognition of fixed point observations. Connections to other parts of observing system facilitated by AtlantOS, JCOMM groups. IOC Executive Council supports revitalization of ocean observing towards 2030.
WP7 INTERNATIONAL AND EUROPEAN NETWORKING OF FIXED-POINT OBSERVATORIES: Creation of the Fixed Platforms Task Team within EuroGOOS to ensure visibility, continuity and sustainability of fixed observation platforms activities at the European level. Convergence of the FixO3 Label with EMSO-ERIC. Organization of the international conference “Time series analysis in environmental science and applications to climate change”.
WP8 OUTREACH AND TRAINING: 3 highly relevant training for 54 international early career scientists using hardware, data and data products as part of their research. The interactive data visualisation components of the project website have been viewed over 135,000 times across the 20+ fixed-points observatories and 80+ parameters currently available. FixO3 project website: The website has received over 100,000 page views from 150+ countries from around the world.
WP9 TRANSNATIONAL ACCESS TO FixO3 INFRASTRUCTURES: Free access to fixed open-ocean observatories: 14 open-ocean observatories and one test-site have been offered under the transnational access framework. 24 scientific and technical projects were granted access to the network. Industrial engagement: More than 30% of the projects involve industrial participants for the test of innovative ocean observing technologies.
WP10 SERVICE ACTIVITIES: All data and products easy accessible to the public. The development of the Service Activities web portal to provide a central and easy accessible point for FixO3 SA-products for a broad public.
WP11 OPTIMISATION OF OCEAN OBSERVING CAPABILITY: Research into an optimum observational network has shown that further measurements are required in the North Atlantic high latitude sea surface and subtropical interior ocean. Cross-calibration and inter-comparison of ocean biogeochemical measurements obtained from different platforms (e.g. moorings, ships, and floats) by different instruments.
WP12 RESEARCH AND DEVELOPMENT ON CRITICAL OBSERVATORY FUNCTIONS: Transfer of FixO3 development of front end electronics to the EMSO Generic Instrumentation Module (EGIM), in addition to the FixO3 innovative sensors (pCO2 and pH sensors).

Potential Impact:
The final results of the project are will be evident as a major increase in data delivery, in an escalation in our interaction with the commercial sector (SMEs), in new technology to enhance observing capability and in a deeper understanding of how fixed point observing systems should function. In addition, through two TNA calls, has been a significant level of collaboration with research groups throughout Europe. By the end of the project the FixO3 Consortium will have, in addition to the specific results highlighted above, provided a roadmap of the way in which European fixed point observatories should be managed in the future.
