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. go.nasa.gov/3Gro3Ts 🌊🪸🐚

Stirring Up Carbonate in the Coral Sea
Fierce storms can dislodge carbonate sediment from shallow underwater platforms and move it into deeper waters.go.nasa.gov
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.

How Dust Affects the World’s Health
NASA research finds that a combination of windblown dust and human-caused particle pollution was associated with nearly 3 million premature deaths in 2019.go.nasa.gov
Depending on the size and type of particles and where they reach in the atmosphere, dust can contribute to warming or cooling, and influence storms and weather events.
