“This project will focus on two [carbon dioxide removal] approaches with direct influence on the ocean sediment: seaweed farming and further sinking into the deep ocean and restoration of ‘blue carbon’ coastal ecosystem, more specifically cessation of bottom trawling to preserve sediment carbon. We will do so by developing a new model for the ocean sediment and benthos that can be coupled to existing ocean models to simulate these strategies and quantify their effect on the carbon cycle as well as understand potential feedbacks that could impact the ocean ecosystem.”
