环境背景。在过去的二十年里，大量和持续的研究工作已经投入到破译海洋浮游生物是否有助于通过生产和释放云播种大气硫来调节气候。我们最近的研究使用全球传播的观测和卫星数据表明，来自海洋的生物硫是南半球大部分原始海洋上空形成云的气溶胶的主要来源。这些气候冷却硫排放积极响应传入的太阳辐射在季节性周期，但显示出微弱的响应，人为的全球变暖预计本世纪。
Environmental context. Over the last twenty years, large and continued research efforts have been invested in deciphering whether oceanic plankton contribute to the regulation of climate by the production and release of cloud-seeding atmospheric sulfur. Our recent research using globally spread observations and satellite-derived data suggest that biogenic sulfur from the oceans represents a major source of cloud-forming aerosols over much of the pristine southern hemisphere oceans. These climate-cooling sulfur emissions respond positively to incoming solar radiation over seasonal cycles, but show a weak response to anthropogenic global warming foreseen for the current century.
