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.

Looking More Deeply Into the Past to Gauge the Planet’s Future

In 1995, biologist Daniel Pauly made a shrewd observation: Scientists in his field had forgotten about the past. Pauly, who studied commercial fishing at the University of British Columbia, observed that fisheries scientists tended to measure change in the abundance and species composition of the fish stocks they studied relative to what they were like at the beginning of their careers. As fish stocks declined, each new generation of scientists generally accepted the new normal as the natural state of things.
