Underwater Earthquakes’ Sound Waves Reveal Changes in Ocean Warming

September 17, 2020 By Carolyn Gramling Science News
Sound waves traveling thousands of kilometers through the ocean may help scientists monitor climate change. As greenhouse gas emissions warm the planet, the ocean is absorbing vast amounts of that heat. To monitor the change, a global fleet of about 4,000 devices called Argo floats is collecting temperature data from the ocean’s upper 2,000 meters. But that data collection is scanty in some regions, including deeper reaches of the ocean and areas under sea ice.
