   What is ocean carbon removal?

   • Ocean carbon removal approaches aim to enhance or accelerate natural biological or chemical processes that sequester carbon in the ocean. In a few cases, the approaches extract carbon dioxide dissolved in seawater for storage on land.

   How can we remove carbon dioxide from the ocean?

   • Researchers are racing to explore these uncharted waters before the climate crisis worsens. Several ocean-based methods of carbon dioxide removal have been proposed (illustrated from left to right): seaweed farming, artificial upwelling and downwelling, enhanced rock weathering, direct ocean capture and ocean iron fertilization.Sayo Studio

   Could the ocean be a potential location for CO2 removal?

   • So far, efforts to remove excess CO2 from the air have largely focused on what can be done on land, such as growing trees or building direct air capture plants. But now a growing number of researchers, companies and even national governments have begun to look at the ocean as a potential location for carbon dioxide removal.

   Could taking carbon dioxide from the ocean make it more absorptive?

   • "We simply can't afford it." Taking carbon dioxide from the ocean could increase its natural ability to remove emissions from the atmosphere, like wringing out a sponge to make it more absorptive.

   How to evaluate ocean carbon dioxide removal methods?

   • In evaluating ocean carbon dioxide removal methods, effectiveness and cost are two big considerations. In this graph, the lines show the estimated range of carbon removal and cost for each method; the circle represents the midpoint. The circle’s size corresponds to how long the carbon might be stored.
