Company info:

In the vast blue expanse of our oceans, a quiet revolution is underway. As we cultivate seaweed at sea, we inadvertently create a novel habitat — one that did not exist before. This artificial ecosystem, characterized by swaying fronds and hidden life, holds promise for biodiversity. Our observations hint at a positive impact, but empirical data remains elusive. Partially funded by the SeaMark project - we aim to investigate the intricate tapestry of life surrounding our seaweed-lines.
