Bubbling carbon dioxide vent discovered on the seafloor off the Philippines

Diving hundreds of feet below the surface of the ocean off the coast of the Philippines, scientists came across a bubbling hotspot of carbon dioxide. And this newly discovered vent might help us predict how coral reefs will deal with climate change, according to a new study.

Bayani Cardenas, a professor in the Department of Geological Sciences at The University of Texas at Austin, accidentally discovered this carbon dioxide fountain while researching the effect of groundwater runoff into the ocean environment in the Philippines's Verde Island Passage.

This strait that runs between the Luzon and Mindoro islands, connecting the South China Sea with the Tayabas Bay, is busy on its surface, serving as a prominent shipping route. It's also busy below the surface, where it harbors one of the most diverse marine ecosystems in the world. And the reefs in this passage, unlike bleached reefs elsewhere, are thriving, according to a statement from The University of Texas.

The researchers named the new hotspot Soda Springs and said that it could have been releasing these bubbles for decades or even millennia.
