From the Ted Talk by Triona McGrath: How pollution is changing the ocean's chemistry

Unscramble the Blue Letters


Now lucky for you, I don't have time to get into the dtiales of the chemistry for today. But I'll tell you as more carbon dioxide enters the ocean, the seawater pH goes down. And this basically means that there is an increase in ocean adicity. And this whole process is called ocean acidification. And it's happening alongside climate change. Scientists have been monitoring ocean aciiotcdiaifn for over two decades. This firuge is an important time series in Hawaii, and the top line shows steadily increasing concentrations of carbon dioxide, or CO2 gas, in the atmosphere. And this is directly as a relust of human activities. The line underneath shows the increasing cacnntoertinos of cabron dioxide that is diselosvd in the surface of the ocean which you can see is iracenisng at the same rate as carbon dioxide in the atpormhsee since mueetanmrses began. The line on the bottom shows then shows the canghe in chreismty. As more carbon dioxide has entered the ocean, the seawater pH has gone down, which basically means there has been an increase in ocean acidity. Now in iaernld, scientists are also monitoring ocean acidification — scientists at the Marine Institute and NUI Galway. And we, too, are seeing acidification at the same rate as these main ocean time-series sites around the world. So it's happening right at our doorstep.

Now lucky for you, I don't have time to get into the details of the chemistry for today. But I'll tell you as more carbon dioxide enters the ocean, the seawater pH goes down. And this basically means that there is an increase in ocean acidity. And this whole process is called ocean acidification. And it's happening alongside climate change. Scientists have been monitoring ocean acidification for over two decades. This figure is an important time series in Hawaii, and the top line shows steadily increasing concentrations of carbon dioxide, or CO2 gas, in the atmosphere. And this is directly as a result of human activities. The line underneath shows the increasing concentrations of carbon dioxide that is dissolved in the surface of the ocean which you can see is increasing at the same rate as carbon dioxide in the atmosphere since measurements began. The line on the bottom shows then shows the change in chemistry. As more carbon dioxide has entered the ocean, the seawater pH has gone down, which basically means there has been an increase in ocean acidity. Now in Ireland, scientists are also monitoring ocean acidification — scientists at the Marine Institute and NUI Galway. And we, too, are seeing acidification at the same rate as these main ocean time-series sites around the world. So it's happening right at our doorstep.
