Worldwide ocean acidity measured

Researchers from the University of California, Santa Barbara have completed a worldwide study of ocean acidification, or pH level.

Scientists used SeaFET sensors to collect data in 15 different coastal ocean locations ranging from the tropical waters of the Line Islands in the Pacific to water beneath 12 feet of sea ice in McMurdo Sound, Antartica.

Each sensor recorded 30 days of continuous pH values, allowing scientists to illustrate how different parts of the world’s oceans have different pH levels and how they might adapt to future climate change.

Acidification is a direct result of increasing greenhouse gas emissions, and limits the amount of carbonate forms in the water, which in turn threatens sea creatures that use carbon to build their skeletons.
