Scientists have developed a satellite technique to capture a near real-time view of ocean acidification.
Their findings, published in the journal Environmental Science and Technology, showing how data from satellites that measure salinity and other ocean conditions could be combined to produce a new way of monitoring acidification.
Oceans are taking in about 90 percent of the excess heat created by human greenhouse gas emissions, but they’re also absorbing some of the carbon dioxide (CO2) itself.
A set of chemical processes dissolves that CO2 and turns it into carbonic acid and sets off a complex changes to the chemistry of seawater, which dissolves shells and coral and creates a cascade effect that could disrupt entire marine ecosystems.
A recent study estimated $1 trillion annually in losses caused by ocean acidification by 2100, if left unmitigated. Some research has looked at “designer” corals and other creatures that could survive more acidic seas but more work needs to be done to figure out just what will thrive (or at least survive) the changing acidity...
