Ms. Martina Doblin – an author of study “This is a whole new species,” said. Research shows that this microorganism has the ability to photosynthesize and release carbon-rich substances that can “trap” other microorganisms before sinking to the sea floor.
The microorganisms above act as a “biological carbon pump”, which combines the process of absorbing carbon from the atmosphere through the cyclic cycle of organic matter, after sinking to the bottom of the ocean, buried for thousands of years. thousand years.
“This process shows that there is likely more carbon sinking in the ocean than we thought, and perhaps the potential is even greater if we let the ocean capture more carbon naturally,” said Ms Doblin.
Based on studies conducted off the coast of Sydney, the researchers estimated the species bacteria This newly discovered is capable of absorbing 0.02-0.15 gigatons of carbon annually globally.
To meet future climate goals, scientists estimate the world needs to remove 10 gigatons of carbon dioxide from the atmosphere each year, by 2050.
Many other cyclic processes and bacteria are also involved in marine carbon sequestration, including phytoplankton, but Prorocentrum cf. balticum is also resistant to ocean acidification and warming.
The study’s lead author, marine biologist Michaela Larsson, said the bacteria’s tolerance to global warming would help natural carbon capture in the future, but would need to be done. much more research if directly using them.
“At this stage, there is little potential for using this process to meet climate goals, and we need to do some important research before we can take the project on scale,” she said. great”.
