Energy Futures Initiative (2020): Uncharted Waters. Expanding the Options for Carbon Dioxide Removal in Coastal and Ocean Environments

Energy Futures Initiative (2020): Uncharted Waters. Expanding the Options for Carbon Dioxide Removal in Coastal and Ocean Environments (Frontiers of CDR: Accelerating Underexplored Solutions to the Climate Crisis).

"Elevated atmospheric carbon dioxide (CO2) concentrations have adversely affected the marine environment in three ways—ocean warming, ocean acidification and deoxygenation—all of which have had deleterious effects on the ocean’s living resources."

Princeton News: What caused the ice ages? Tiny ocean fossils offer key evidence

"Some data suggested that, during ice ages, CO2 was trapped in the deep ocean, but the reason for this was debated. Now, an international collaboration led by scientists from Princeton University and the Max Planck Institute for Chemistry (MPIC) have found evidence indicating that during ice ages, changes in the surface waters of the Antarctic Ocean worked to store more CO2 in the deep ocean."

Ai, Xuyuan E.; et al. (2020): Southern Ocean upwelling, Earth's obliquity, and glacial-interglacial atmospheric CO2 change

Ai, Xuyuan E.; Studer, Anja S.; Sigman, Daniel M.; Martínez-García, Alfredo; Fripiat, François; Thöle, Lena M. et al. (2020): Southern Ocean upwelling, Earth's obliquity, and glacial-interglacial atmospheric CO2 change. In Science (New York, N.Y.) 370 (6522), pp. 1348–1352. DOI: 10.1126/science.abd2115.

"Here, high-resolution diatom-bound nitrogen isotope measurements from the Indian sector of the Antarctic Zone reveal three modes of change in Southern Westerly Wind–driven upwelling, each affecting atmospheric carbon dioxide."

Bertram, Christine; Merk, Christine (2020): Public perceptions of ocean-based carbon dioxide removal technologies: the nature - engineering divide

Bertram, Christine; Merk, Christine (2020): Public perceptions of ocean-based carbon dioxide removal technologies: the nature - engineering divide. In Front. Clim. 2, p. 31. DOI: 10.3389/fclim.2020.594194.

"We outline past work on the public perceptions and acceptability of ocean-based CDR among laypersons covering the main developments over the past 15 years. We compare and synthesize insights from two distinct strands of literature – one on climate engineering approaches and the other on coastal ecosystem management or blue carbon approaches."

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."
