RWE partners with DHI and other leading marine scientists to monitor biodiversity using an ecosystem-based approach at its Kaskasi offshore wind farm

As part of a new partnership with leading scientists to improve monitoring of marine life, global energy company RWE has launched the SeaMe (Sustainable ecosystem approach in Monitoring the marine environment) project at its Kaskasi offshore wind farm off the German coast. The objective is to gain a comprehensive understanding of the interactions between offshore wind farms and the ecosystem through the use of a sound scientific approach, together with new AI-based and CO2-minimising monitoring technologies.
The three-year project ‘SeaMe’ uses innovative monitoring technologies – including a drone and an autonomous underwater vehicle, both equipped with AI-based cameras, as well as environmental DNA sampling. Simultaneous integration of all collected data will enable monitoring of the ecosystem within the Kaskasi offshore wind farm with the goal of reducing carbon intensity of monitoring as well as minimising the impact on marine life.
 
‘The SeaMe project is a great example of the increasing focus on biodiversity protection in offshore renewables, and we are proud to support the project with our tools and expertise. Our innovation in methods for quantifying biodiversity metrics can make a tangible difference in global efforts to restore and protect biodiversity,’ states Mikael Kamp Sørensen, Executive Vice President for Energy &amp; Ports in DHI.
 
Innovative and ecosystem-based biodiversity monitoring approachOffshore wind is vital to tackling climate change and reducing greenhouse gas emissions. However, it is equally important to ensure that possible impacts on the environment are minimised and mitigated. It is already mandatory by law in many countries to assess and monitor the state of the environment where offshore wind farms are developed, built and operated. These legal requirements, however, often focus on monitoring individual groups of organisms (e.g. fish, marine mammals, birds), and there has been no holistic approach to data gathering.
 
Thanks to new technologies, the simultaneous collection of data and effective data management, the SeaMe project will enable RWE to consider the ecosystem as a whole. One aim of the SeaMe project is to also monitor key components of the marine ecosystems that are usually left out of conventional monitoring programmes, such as small phytoplankton (microscopic algae) and zooplankton (e.g. krill), which play a vital role in feeding larger animals. In addition, a series of physical parameters such as temperature, salinity and oxygen will be measured to explain any possible changes in the distribution and abundance of species.
 
DHI will contribute to the SeaMe project as data coordinators, data host and data analysers. DHI will develop and host a data portal for RWE, where all the biodiversity data harvested from the main project will be stored and made available to all involved parties. The data portal will enable visualisation of all the different data streams and support scientifically-based communication and dissemination of the collected ecological data.
 
Furthermore, DHI will process the collected data with their EBM BioQ suite, which is a collection of analytical tools for ecosystem-based management. For example, DHI’s Biodiversity State Indicator (BSI) will be applied to assess the state of biodiversity at the site.
 
Deployment of more environmentally friendly monitoring techniquesThe joint project will investigate how innovative techniques can make monitoring less invasive and more sustainable compared to the current monitoring techniques. Whereas planes and ships are routinely used to monitor birds and mammals, SeaMe targets to replace these methods with a drone equipped with an AI-based camera system. SeaMe will also collect water samples and analyse them for environmental DNA. AI-based fish video monitoring will be performed using an autonomous underwater vehicle. Both methods will replace the traditional means of sampling the fish using nets, making the entire process less invasive. DHI will act as advisors for the data providers, providing advice on sampling strategy for eDNA and other novel monitoring technologies. 
 
Leading marine scientists to contribute their know-howRWE’s SeaMe project will be carried out in collaboration with prominent partners including the Helmholtz Institute for Functional Marine Biodiversity at the University of Oldenburg (HIFMB), the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI), BioConsult SH, the German Research Centre for Artificial Intelligence (DFKI) and DHI. 
 
All tests will take place at RWE’s Kaskasi offshore wind farm, which is located 35 kilometres off the coast of the German island of Heligoland. With a total installed capacity of 342 megawatts, the wind farm is capable of supplying the equivalent of approximately 400,000 German homes with green electricity.

DHI will join delegates from around the world at COP 16 in Cali, Colombia this October to address urgent challenges in biodiversity conservation and restoration.&nbsp;
COP 16 will bring together governments, observer organisations, indigenous communities, businesses, civil society, academia and the general public under the theme ‘Peace with nature’ and with participants from over 190 countries. This year's discussions will emphasise innovative technologies and analytical approaches that are critical for developing effective solutions to protect and restore biodiversity.
How DHI works with marine biodiversity&nbsp;
Marine biodiversity is a critical element in maintaining ecosystem functionality, which in turn supports industries and livelihoods globally. Yet, the lack of standardised biodiversity metrics presents a challenge in monitoring, assessing and mitigating biodiversity loss. Clients are increasingly challenged by the lack of standards and proven methods for reporting on the biodiversity impact of their business activities across industries and sectors.&nbsp;
&nbsp;
DHI has developed comprehensive, science-based methodologies that safeguard biodiversity and promote sustainable ecosystem management on a global scale. These methodologies support biodiversity initiatives through integrated solutions for monitoring, analysing, reporting, enhancing and restoring marine ecosystems.
&nbsp;
Collaborating with industries such as shipping, ports and offshore wind, DHI provides structured guidance to address biodiversity concerns while ensuring regulatory compliance.&nbsp;

Restoring the critically endangered Hillman Marsh ecosystem using nature-based solutions

DHI has partnered with SJL Engineering Inc. and the Essex Region Conservation Authority to restore the critically endangered Hillman Marsh ecosystem on Lake Erie, leveraging MIKE Powered by DHI technology to design nature-based solutions. This initiative is supported by grant funding from Environment and Climate Change Canada (ECCC) under the Great Lakes Freshwater Ecosystem Initiative (GLFEI).
Covering nearly 1,000 acres, Hillman Marsh is a designated Provincially Significant Wetland. Historically, the marsh was a thriving ecological system providing critical habitat to aquatic endangered species and numerous migratory bird populations, while providing ecosystem services such as water quality benefits. However, cumulative stresses from human development and climate change, particularly rising lake levels, have severely threatened its ecological value.
 
In addition to the significant loss of habitat and ecosystem services once offered by the Hillman Marsh, the propagation of lake waves through the newly breached barrier system and into the marsh presents a significant risk to the residents and agricultural lands within the interior of the Pelee Peninsula on Lake Erie, in Ontario Canada. The marsh is surrounded by a perimeter of dykes, which were constructed from native local materials including clay and peat. The interior lands are low-lying, with much of the Pelee Peninsula featuring elevations well below the 100-year flood level. There is potential for widespread flooding of more than 2,000 hectares and direct economic damages on the order $50,000,000 should the dyke suffer a breach based on the historical 100-year flood level.  
Reinstating 1,000 acres of wetland providing ecological, habitat, carbon sequestration and water quality services
 
The overall objective of the Hillman Marsh and Barrier Beach Restoration Project is to create a restored marsh environment with protection from lake waves and storm surge achieved through the design and implementation of a nature-based, dynamically stable, engineered artificial barrier feature. The restored marsh will serve to reinstate approximately 1,000 acres of wetland providing ecological, habitat, carbon sequestration and water quality services. The restored barrier system will ensure that these services are maintained in the future with increased resilience to the sheltered marsh and surrounding region against climate-related impacts on coastal processes.
 
To achieve this, the barrier is to be designed in a hybrid manner, combining several approaches to reduce wetland exposure, increase resilience and provide shoreline stability including traditional engineering techniques (e.g. breakwaters, headlands, reinforced dykes) with nature-based or green infrastructure (e.g. artificial reefs, sediment bypassing, beach nourishment, boulder clusters, dune restoration, barrier re-vegetation, etc.).
 
MIKE models key in designing nature-based solutions for effective restoration
 
In early September, DHI’s team in Canada commenced this multi-year project with a comprehensive field campaign, deploying wave monitoring, streamflow and water level monitoring instrumentation within the marsh. 
‘Our team will use the MIKE 21 FM Spectral Waves, Hydrodynamics, MIKE 3 Mud Transport and MIKE 3 Wave FM models to assess the marsh baseline and to develop nature-based hybrid design solutions to protect and restore the marsh habitat’, says Danker Kolijn, Project Director Americas-Pacific, DHI. 
He adds, ‘Our numerical models will integrate vegetation dynamics and morphological processes to understand the response of the system to future climate stressors and the proposed solutions. The final concept will be tested and refined in the physical model basin at the Federal Ocean, Coastal and River Engineering Research Centre in Ottawa, Canada. Once the design has been refined, plans will be prepared for the implementation, construction, monitoring and long-term adaptive management of the project.’
