This 𝗪𝗼𝗿𝗹𝗱 𝗢𝗰𝗲𝗮𝗻 𝗗𝗮𝘆, we are spotlighting the role digital twins can play in supporting healthier oceans and more sustainable marine management. In Denmark, DHI is collaborating with the Danish Agency for Green Transition and Aquatic Environment, Styrelsen for Grøn Arealomlægning og Vandmiljø, to develop an Integrated Marine Monitoring (IMM) system that connects satellite observations, in-situ measurements and ecosystem modelling into a more complete picture of ocean conditions. In 2026, the project has continued to advance with more models and expanded data assimilation, with a focus on bringing both hydrodynamic and biogeochemical models into operational use. We have also placed emphasis on validating the results and ensuring data quality, building workstreams for data import/export and operational data quality assurance. Recent developments include data assimilation of light attenuation coefficient, which has been challenging but is now delivering promising results. Later this year, we will explore the assimilation of chlorophyll data from different sources, as it is a key indicator of phytoplankton activity and marine ecosystem health. The aim is to explore the best combination of data sources and fully understand their benefits and limitations. Since the initial phase, quality has been a cornerstone of the project. While there will be parts of the Danish marine waters that cannot yet be described sufficiently well by the models, the overall aim is to have a system that complements the Danish national monitoring programme, making data quality a key requirement. #WorldOceanDay #DigitalTwins
