Coral Bank in the Artic: Cold-Water Corals as Architects of Marine Biodiversity

Cold-water corals are important ecosystem engineers, creating biodiversity hotspots in the deep sea that serve as vital habitats for up to 1,200 species. Thousands of years old, coral reefs form complex structures that provide shelter and nursery grounds for numerous marine organisms. Research on cold-water corals gained momentum in the last two decades due to advancements in deep-sea exploration technology. These ancient corals serve as valuable archives of past environmental conditions. Over 50% of cold-water coral ecosystems have been destroyed, mainly due to bottom trawling before their significance was recognized. The ongoing climate crisis poses additional threats, as warming waters and melting ice alter ocean currents and water properties. These changes directly impact cold-water corals, leading to significant shifts in ocean dynamics and the delicate ecosystems they support.

This research serves as the foundation of the architectural concept for the coral bank. Located in the north of Norway on the island of Sorøya, which borders the most northern coral reef, Korallen, the project is set in a unique location where the main path encloses a bay that serves as the coral nursery. This path guides researchers and visitors from underwater, into the water, onto the rocks, and into the rocks. Inspired by the life cycle of the coral, the design includes two buildings: the wet lab in the water hosting a biobank, a coral nursery, and research facilities, while the dry lab in stone serves as the core structure with the archive and educational facilities. The path is essential, acting as the spine of the project with several facilities along the water. This innovative design facilitates essential research and conservation strategies for cold-water corals. It provides an immersive educational experience, allowing visitors to understand the importance of cold-water coral ecosystems and the urgent need for their protection.
