Ocean acidification (Video)

Ocean acidification happens because on land we release carbon dioxide into the atmosphere.

That carbon dioxide comes back into the ocean. You have increased CO2 in the water and the water simply becomes more corrosive. It permeates through the food chain all the way up to the upper levels.

The buoy is an APL product and there are NOAA sensors riding on the buoy. We’re measuring the pH, which tells us directly how acidic the water is becoming.

These buoys are going to give us real time data every single day on the condition — the health — of Puget Sound, Hood Canal, and the coast of Washington.
