The ocean twilight zone could store vast amounts of carbon captured from the atmosphere

The Hindu  

Deep below the ocean surface, the light fades into a twilight zone where whales and fish migrate and dead algae and zooplankton rain down from above. Peter de Menocal, a marine paleoclimatologist and director of Woods Hole Oceanographic Institution, discussed ocean carbon dioxide removal at a recent TEDxBoston: Planetary Stewardship event. So, for taking carbon out of the atmosphere and storing it someplace where it won’t continue to warm the planet, the ocean is the single biggest place it can go. Ocean carbon dioxide removal, or ocean CDR, uses the ocean’s natural ability to take up carbon on a large scale and amplifies it. Moreover, if we were to try any of these carbon removal technologies at any scale right now, we wouldn’t be able to measure or verify their effectiveness or assess impacts on ocean health and ecosystems.

Takeaways from Associated Press report on efforts to capture carbon in the ocean

Associated Press  

HALIFAX, Nova Scotia — A growing industry is racing to engineer a solution to global warming using the absorbent power of the oceans. Dozens of companies and academic groups are pitching the same theory: that sinking rocks, nutrients, crop waste or seaweed in the ocean could lock away climate-warming carbon dioxide for centuries or more. Most of the ocean startups …

Ocean dumping – or a climate solution? A growing industry bets on the ocean to capture carbon

Associated Press  

HALIFAX, Nova Scotia — From the grounds of a gas-fired power plant on the eastern shores of Canada, a little-known company is pumping a slurry of minerals into the ocean in the name of stopping climate change. Though Planetary’s work can sound like some “scary science experiment,” Burt said, the company’s testing so far suggests that magnesium oxide poses minimal …

What is carbon capture?

The Hindu  

Global warming is the result of certain greenhouse gases — but especially carbon dioxide — building up in the air and preventing the planet from cooling as quickly as it would without them. Although some natural processes emit these gases, their build-up to dangerous levels is entirely due to emissions from human industrial activity, including the combustion of fossil fuels …
