Ocean carbon removal approaches aim to enhance or accelerate natural biological or chemical processes that sequester carbon in the ocean. Improving our understanding and facilitating the development of oceans’ carbon removal mechanisms are essential to addressing climate action. Of the various marine CDR technologies proposed to date, ocean alkalinity enhancement (OAE) has the largest potential and boasts many advantages, such as mitigating ocean acidification and having a high degree of permanence.

Given the rapidly growing interest in this area, a science-based, research-led, iterative and adaptive approach in collaboration with innovative technology from industry will provide a better understanding of the potential of OAEs and strike an optimal balance between the urgency of combating climate change, the importance of protecting our natural resources, and realizing on this economic opportunity.

Learn more about OAE and the OCEAN ALK-ALIGN project which involves an international consortium of researchers from Canada, Germany and Australia to advance knowledge essential for OAE implementation.

Dr. Dariia Atamanchuk is a Research Associate at the Ocean Science and Technology group at Dalhousie University, Halifax, Canada. Dariia’s research activities focus on studying ocean biogeochemical cycling of EOVs (and beyond) using observations from autonomous platforms and sensors as primary tools. These include in situ and ship-borne observations of coastal environments (Scotian Shelf, KoljoFjord, Bedford Basin Time-Series) and the open ocean (Labrador Sea, North Atlantic) concerning the carbon cycle (pCO2, pH, TA), oxygen, nutrients (nitrate and phosphate), chlorophyll, bio-optical properties of seawater, velocity and more.
