Presentation #1

Speaker: Dr. Adam Yang (Assistant Professor, Coastal Hydraulics, Department of Civil & Resource Engineering, Dalhousie University)

Topic: Seeding alkaline mineral particles in the ocean: an effective CO2 removal solution?

Description: From shore to open ocean, introducing finely ground alkaline minerals into the water—a process known as ocean alkalinity enhancement (OAE)—can help remove atmospheric carbon dioxide. However, this method is most effective when particles remain suspended in the upper ocean long enough to dissolve. While traditional models assume particles sink slowly at the rate of individual grains, our study reveals that they may sink much faster due to fluid instabilities in dynamic ocean conditions, shortening their dissolution window. This finding underscores the importance of accounting for ocean currents and mixing when designing OAE strategies for carbon dioxide removal.

Bio: Dr. Adam Yang is an Assistant Professor in Coastal Hydraulics in the Department of Civil and Resource Engineering at Dalhousie University. His research focuses on environmental fluid mechanics, with particular interests in marine carbon dioxide removal, sediment transport, and stratified turbulence. He holds a PhD in Civil Engineering from the University of British Columbia and has postdoctoral experience at Yale University’s Center for Natural Carbon Capture
