Ocean-Based Carbon Capture and Storage: Mineral Weathering and Alkalinity Enhancement


What this project investigates: The ocean environment, from seafloor to surface, to better understand the potential for large-scale oceans-based carbon capture and storage. 

How this will be addressed: By modeling the optimal wind/wave settings for mineral dust deposition, rates of mineral dissolution across a range of marine environments, and the unintended negative consequences of enhanced mineral weathering in the oceans. 

Why it matters: The oceans have a tremendous potential for capturing and storing greenhouse gases. However, scientists currently have a limited understanding of the potential consequences of increasing the oceans’ ability to capture and store greenhouse gases for marine environments. This modeling study will provide scientists with the understanding needed to plan and execute meaningful field trials.
