Offshore, a phytoplankton bloom forms a bright green swirl in the ocean water, proof of the productivity that triggers the deadly eruptions.
离岸远些，茂盛的浮游生物在海水中形成碧绿色的涡状形，这就是海洋生物生产力触发致命喷发的证据。
Individual phytoplankton are tiny, but when they bloom by the billions, the high concentrations of chlorophyll and other light-catching pigments change the way the surface reflects light.
