Plankton--which are the base of the oceanic food-web on which our fisheries depend and remove carbon dioxide from the atmosphere and sequester it in the ocean--live on small scales. Turbulent mixing--which is key to the transport of nutrients and oxygen, as well as greenhouse gases, throughout the ocean and has been directly implicated in the feeding and survival of plankton--happens on small-scales. In addition to being able to alter whole ecosystems (to the benefit or detriment of our fisheries) through shifts in food availability and timing, certain plankton can have immediate impacts on our oceans: harmful algal blooms (HABs) can render waters toxic. Predicting the future ocean hinges on an understanding of small-scale bio-physical processes.

浮游生物是我们渔业所依赖的海洋食物网的基础，它们从大气中吸收二氧化碳并将其封存在海洋中，它们生活的规模很小。湍流混合-这是整个海洋营养物和氧气以及温室气体运输的关键，并直接涉及浮游生物的摄食和生存-发生在小尺度上。某些浮游生物除了能够通过食物供应和时间的变化改变整个生态系统（对我们的渔业有利或有害）外，还能对我们的海洋产生直接影响：有害藻华可使沃茨有毒。预测未来的海洋取决于对小规模生物物理过程的理解。
