At GEOMAR, we are developing Digital Twins of the Ocean using a process-oriented and co-designed approach. Instead of building one large model, we create modular systems that reflect local needs and priorities. A key focus is the West African region, with its unique environmental and social challenges. These digital twins combine in-situ measurements, satellite data, and advanced models that...

Imagine a world, where data and information can be easily and effectively shared, linked, transformed, and combined to answer future research questions and plan sustainable governance actions. Digital twins are one viewpoint from which to build the technologies needed to establish the required interoperability and transparency of data products and predition methods. This presentation will...

The growing interest in digital twin technology has excited numerous initiatives, also in the realm of the Earth system sciences; however, time-constraint funding often results in infrastructure solutions that, despite aiming for e.g. accessibility and interoperability, at worst remain effectively proprietary and centralized. This contribution proposes an alternative: a community-driven...

In the past years, data driven machine learning models have revolutionized numerical weather prediction, outperforming traditional numerical models for the atmosphere both in efficiency and precision. Trained on reanalysis data, these models enable the generation of much larger simulation ensembles and, due to their differentiable architecture, offer new and efficient ways to directly...

Marine ecosystems are under enormous pressure from anthropogenic activities. Adequate management and protection of marine ecosystems in the context of a sustainable "blue economy" requires that we understand where animals move, what habitats they need, and how their movements are affected by offshore developments. However, our knowledge is insufficient, even in well-studied systems such as the...

The Western Baltic Sea (WB) is under increasing impacts from climate change and biodiversity degradation caused by eutrophication, pollution, increased land use and increased resource uptake. Between 1994 and 2019, WB has been overfished, leading to fish stock depletion of cod (Gadus morhua), herring (Clupea harengus), and sprat (Sprattus sprattus). The interconnected dynamics between...

The ocean and its biodiversity are vital to life on Earth. Understanding their current state and how that state may change requires comprehensive data on biodiversity and related pressures. Protecting and restoring biodiversity is a key goal of the Horizon Europe Mission to restore oceans and waters by 2030, supporting the EU Green Deal and Biodiversity 2030 targets. A Digital Twin of the...

With underwater noise pollution increasing globally—and formally recognized under the EU Marine Strategy Framework Directive (MSFD, Descriptor 11)—significant knowledge gaps remain regarding its effects on marine life, especially invertebrates. Addressing this requires monitoring and predicting the key elements of underwater noise, acoustic pressure and particle motion, while accounting for...

The El Niño–Southern Oscillation (ENSO) profoundly influences global climate variability, with cascading impacts on regional precipitation, marine ecosystems, and socioeconomic systems. Reliable monitoring and early prediction of ENSO are thus essential for supporting next-generation ocean decision-making frameworks, including future Digital Twin of the Ocean (DTO) systems. This presentation...

Digital ocean twins (DOTs) are applications that bring together data and expert knowledge to support decision-making for sustainable ocean management. In the SEADOTs (Social-Ecological Ocean Management Applications using Digital Ocean Twins) project, we integrate social, economic, and ecological data with data on human activities, ocean data, ecosystem data, and a variety of models into DOTs....

Risk from climate hazards is commonly defined as the interplay of hazard, exposure, and vulnerability. In recent years, response capacity and adaptation have been recognized as additional dimensions in comprehensive risk frameworks. Digital twins offer a powerful approach to integrate all these components into one coherent and dynamic system. However, to adequately assess risk, digital twins...

The EOM working group is engaged in the development of remote sensing-based evaluation algorithms for the analysis of terrestrial and aquatic ecosystems. We use different sensors to map coastal areas, and in particular shallow water zones, from cm to decameter scale. Examples are water depth, water constituents (e.g., Chl, TSM), benthos mapping (seagrass, macroalgae), floating algae or beach...

Coastal urban areas face increased risk from storm surge induced flooding due to accelerating sea level rise and continued urban expansion, without adaptation leading to exacerbated flood damages in the future. Thus, enhanced preparedness is essential to minimize damages, especially for coastal cities that have not yet adapted to the increasing risk. Despite their computational demands...

Maritime transports are the backbone of global economics, while they account for 3% of global emissions. We report on research at DLR to support the shipping industry in increasing the safety of operations and, at the same time, reduce the carbon footprint of these operations. Digitalization and live integration of simulations with in-situ sensor data are key aspects to enable the use of new...

Exploring seafloor morphology and benthic habitats is essential for understanding the interactions between biology and geology. While findings have traditionally been shared through maps and graphs, effectively communicating environmental change and mitigation scenarios to stakeholders is becoming increasingly important. Immersive and dynamic environments offer a new way of transferring...

Aquatic life plays a crucial role in human well-being by supporting biodiversity, regulating climate, and contributing to food security. Plankton, in particular, drive the biological carbon pump, which sequesters large amounts of atmospheric carbon in the ocean. However, climate change threatens this system by altering plankton diversity and reducing food web efficiency, impacting both marine...

The SWOT mission has opened a new chapter in understanding mesoscale and sub-mesoscale ocean dynamics, providing a constantly growing amount of high-resolution Sea Surface Height (SSH) observations. However, this extremely valuable repository of data is still not fully exploited by researchers, largely due to technical reasons and the novelty of the product. In particular, the KaRIn...

The Baltic Sea is under pressure. Eutrophication and global warming are threatening the ecosystem. Among other things, coastal hypoxia continues to increase despite many efforts to reduce nutrient inputs. New, dynamic evaluation tools are needed to decipher the complex drivers behind these problems and take more effective measures. Applying machine learning to complex environmental data could...

Extreme water levels along the German Baltic coast, primarily driven by storm surges, are posing increasing risks due to climate-induced sea level rise. To support flood-risk manage-ment in coastal areas and enhance climate resilience, we present a prototype model, which is intended to be integrated on a Digital Twin of the Coast for the Kiel region, from Damp to Hohwacht. Based on a...

The dispersal of marine pathogens is governed by a combination of physical processes such as Lagrangian transport with the ocean currents, and biological processes such as the development of either pathogens or host specimens based on ambient conditions, or local population dynamics. The processes governing pathogen dispersal can be described in terms of different parameters. In general, the...
