to evaluate the ocean’s capacity to store carbon and to study how this might be impacted in future climate scenarios. Through one of the primary carbon storage mechanisms, the biological carbon pump, ...

and pump it into holes in the sea bed. The scientists call their project Solid Carbon because, if it works as they expect, the CO2 they inject will forever be rock at the bottom of the ocean.

Ocean ecosystems play a critical role ... other organisms in a phenomenon known as the “whale pump”. Crustaceans and fish transport carbon and nutrients by feeding in surface waters during ...

Without this biological carbon pump, atmospheric carbon dioxide levels would be around 50 per cent higher than they are today. But as our ocean warms, this zooplankton community is changing ...

By introducing clay dust into the marine ecosystem, researchers aim to enhance the efficiency of the biological pump—a natural cycle that transfers carbon from the atmosphere to the deep ocean.

It has absorbed about 90% of the heat humans have generated through greenhouse gas emissions, and absorbs around a quarter of all carbon dioxide emissions. The biological pump is the ocean’s ...
