Turbine foundation design creates new home for marine life
Utility Vattenfall and nature conservation organization The Rich North Sea (De Rijke Noordzee) started a joint study to find out if turbine foundations can support marine life. While previous studies focused on nature enhancement projects in the vicinity of turbines, both organizations want to know if the structures themselves can contribute to nature development. Water replenishment holes in the foundations offer an opportunity for fish and other marine species to enter and leave again. The study is aimed at finding if they use the inside of the turbine foundations to settle, shelter and as a feeding ground. The study is conducted at the Hollandse Kust Zuid wind farm.

Flat oysters thrive in the Blauwwind wind farm: survival of over 96%
A team of researchers went to the Borssele III & IV wind farms to monitor the 2,400 outsourced flat oysters. The oyster tables were placed at the base of four wind turbines in October 2020. Ecologist Renate Olie is enthusiastic: "The baskets are full of life and the survival of the oysters is high, so that's good news."

Lost oyster reef is being restored
Two centuries ago, about 20% of the seabed of the Dutch North Sea was covered with large oyster reefs. Nowadays, there are hardly any wild oyster reefs to be found in the North Sea. Researchers from the Rich North Sea and Gemini Windpark are joining forces to restore one of the largest oyster reefs that the North Sea has ever had. In the windpark of Gemini, 85 km off the north coast of The Netherlands, they have taken the first steps to rebuild an oyster reef the size of no less than eight football fields.

In conversation with colleagues: so much to learn underwater
The Rich North Sea consists of a team of dedicated professionals from The North Sea Foundation and Nature & Environment. Day in and day out, they work hard for a healthy North Sea, rich in nature, full of life and a source of renewable energy. We talk to two of them: Frank Jacobs (project manager) and Renate Olie (marine ecologist). They talk about their motivation, their work and about their passion for the North Sea.

8.5 million euros from the Dream Fund kicked off The Rich North Sea
The De Rijke Noordzee project received a huge boost from a contribution of 8.5 million euros from the National Postcode Lottery's Dream Fund. This grant enabled De Rijke Noordzee to enhance underwater nature in wind farms on a large scale for the first time. Three years later, we look back: has our dream of a rich North Sea actually come closer?

Partners in sustainability: about our partnership with ASN Bank
From the very beginning, ASN Bank has been involved in the creation of De Rijke Noordzee. ASN Bank has been a partner of De Rijke Noordzee since 2018. Biodiversity and climate are two pillars where ASN Bank and De Rijke Noordzee strengthen each other. We are curious about this special partnership and asked Arie Koornneef, Director of ASN Bank.

Research on cod and lobster behaviour around artificial reefs in wind farm Borssele I and II
Ørsted, The Rich North Sea, Wageningen Marine Research and the Win-Wind consortium have recently launched a study on the behaviour of cod and lobster in Ørsted’s wind farm Borssele 1&2. Ørsted has installed four artificial reefs in the windmill park in the fourth quarter of 2020, in line with its ambition to design nature-inclusive offshore wind farms. Researchers use transponders to study these species that have a marked preference for hard substrate, such as artificial reefs, in their direct living environment. Moreover, eDNA samples will be taken from the water to provide insight into the development of biodiversity on the artificial reefs. The offshore wind farm has been fully operational since the last quarter of 2020. The official opening will take place on September 6th 2021.
