World Resources Institute: Leveraging the Ocean's Carbon Removal Potential

"As the need for climate action becomes more urgent, the ocean is gaining attention as a potential part of the solution. Approaches like investing in offshore energy production, conserving coastal ecosystems and increasing consumption of sustainable ocean-based protein offer opportunities to reduce emissions. In addition to these opportunities, a range of ocean-based carbon removal approaches could help capture and store billion of tons of carbon."

McKinley, Galen A.; et al. (2020): External Forcing Explains Recent Decadal Variability of the Ocean Carbon Sink

McKinley, Galen A.; Fay, Amanda R.; Eddebbar, Yassir A.; Gloege, Lucas; Lovenduski, Nicole S. (2020): External Forcing Explains Recent Decadal Variability of the Ocean Carbon Sink. In AGU Advances 1 (2). DOI: 10.1029/2019AV000149.

"Here, we use an idealized upper ocean box model to illustrate that two external forcings are sufficient to explain the pattern and magnitude of sink variability since the mid‐1980s."

Fast Company: Forget planting trees: This company is making carbon offsets by putting seaweed on the ocean floor

"Running Tide grows kelp, which sucks carbon from the atmosphere. Then it just lets it sink to the ocean floor, where the carbon will stay for a thousand years."

Phys.org: $500 billion question: What's the value of studying the ocean's biological carbon pump?

"Due to limited research, scientists aren't sure exactly how much carbon is captured and stored—or sequestered—by the ocean each year or how increasing CO2 emissions will affect this process in the future."

Digdaya, Ibadillah A.; et al. (2020): A direct coupled electrochemical system for capture and conversion of CO2 from oceanwater

Digdaya, Ibadillah A.; Sullivan, Ian; Lin, Meng; Han, Lihao; Cheng, Wen-Hui; Atwater, Harry A.; Xiang, Chengxiang (2020): A direct coupled electrochemical system for capture and conversion of CO2 from oceanwater. In Nat Comms 11 (1), p. 4412. DOI: 10.1038/s41467-020-18232-y.

"Capture and conversion of CO2 from oceanwater can lead to net-negative emissions and can provide carbon source for synthetic fuels and chemical feedstocks at the gigaton per year scale. Here, we report a direct coupled, proof-of-concept electrochemical system that uses a bipolar membrane electrodialysis (BPMED) cell and a vapor-fed CO2 reduction (CO2R) cell to capture and convert CO2 from oceanwater."
