Abstract
An emerging technology for building capacity to make decisions in the ocean space is the development of Digital Twins of the Ocean (DTOs). A DTO is a virtual replication of the ocean environment, including its properties, behaviors, and processes (https://www.mercator-ocean.eu/en/digital-twin-ocean/). These digital replicas are created using a combination of real-time data collected from satellites and thousands of sensors deployed around the world, as well as outputs of advanced models and computer simulations.
