Fierce storms over the ocean can dislodge carbonate sediment – like from coral, algae and hard shells of marine life – from shallow water and move it deeper into the ocean.

This process may have important implications for ocean acidification. https://go.nasa.gov/3Gro3Ts 🌊🪸🐚

In Feb. 2023, Tropical Cyclone Gabrielle passed over shallow waters at the Bellona Plateau in the Coral Sea.

The storm suspended carbonate sediment that then drifted into deep ocean waters.

This process can help counter ocean acidification from rising carbon dioxide in the atmosphere.

But scientists are still investigating how climate change might be changing the marine carbon cycle. https://go.nasa.gov/3Gro3Ts
