Interoperability Architecture for a Digital Ocean (TURTLE)

The “Interoperability Architecture for a Digital Ocean” (TURTLE) project is implemented by SINTEF Ocean, Norway. Its goal is to coordinate ongoing international Digital Twins of the Ocean projects and work towards an interoperability architecture. As initiatives around the globe begin to enhance ocean-oriented digital capacity, there are unprecedented opportunities to power digital twinning.

Currently there are many initiatives that work toward or in support of a Digital Twin of the Ocean, e.g. the EU Digital Twin Ocean system, NOAA’s National Centre for Environmental Information, the IOC Ocean Data and Information System ODIS, the IOC Ocean Best Practice System OBPS, the Ocean Data Action Coalition and the UN Data Coordination Group.

DITTO’s Priority Activities are

  • a) Articulate and advance a common understanding of Digital Twins of the Ocean architecture.
  • b) Advance a number of “use case” prototype Digital Twin applications across the spectrum from science, engineering and operations; and
  • c) Encourage the formulation of DITTO related Decade Projects.

Motivated by this, TURTLE proposes to coordinate ongoing initiatives to address priority activity a) and work towards an interoperability architecture for the Digital Twins of the Ocean.
