Climate change: Earthquake ‘hack’ reveals scale of ocean warming – Yahoo News Australia
Using sound waves from underwater earthquakes, researchers can more accurately measure sea temperatures.
Scientists have found a clever new way of measuring ocean warming, using sound waves from undersea earthquakes.
The researchers say the “hack” works because sound travels faster in warmer water.
The team looked at sonic data from the Indian Ocean emitted by tremors over a 10-year period.
