Phys.org: Could kelp help relieve ocean acidification?

"Ethereal, swaying pillars of brown kelp along California's coasts grow up through the water column, culminating in a dense surface canopy of thick fronds that provide homes and refuge for numerous marine creatures. There's speculation that these giant algae may protect coastal ecosystems by helping alleviate acidification caused by too much atmospheric carbon being absorbed by the seas."

Project: Oceans 2050: Seaweed Carbon Farming

"This study builds on Professor Duarte’s research, featured in Nature, on ocean restoration by further assessing the role of seaweed aquaculture as a key recovery wedge for the world’s oceans and the climate. These efforts will set the robust scientific foundation to support the development of a new voluntary carbon protocol for seaweed aquaculture, which will be a public good and allow seaweed farmers to monetize the carbon impact of their activities for the first time."

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."
