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.

Despite their natural efficiency in capturing carbon, this can be inhibited by a deficiency of key nutrients such as iron — which is essential for phytoplankton growth and photosynthesis. In ...

A new B.C.-led study has mapped 274 carbon hot spots found on Canada's sea floor. Flat, cold and seemingly devoid of life — ...

The vertical migration of Antarctic krill may play a smaller role in oceanic carbon storage than previously believed, according to a year-long study in the Southern Ocean. The findings challenge ...

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 ...

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.

Organic carbon typically breaks down in most environments. Yet, vast amounts remain preserved in marine sediments, a mystery that has puzzled scientists for decades. Over time, preserved organic ...
