Richard Feely, an oceanographer with the National Oceanic and Atmospheric Administration, explains that before the die-offs began, “What we knew at the time was that many organisms as adults are sensitive to acidification. What we did not know is that the larval stages of those organisms are much more sensitive.” By 2014, the same
