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.

浮游生物是海洋食物网的基础，我们的渔业赖以生存，它们从大气中吸收二氧化碳并将其封存在海洋中，它们的生活规模很小。湍流混合是在整个海洋中输送营养物质和氧气以及温室气体的关键，并直接影响浮游生物的摄食和生存，但它发生在小范围内。除了能够通过改变食物供应和时间来改变整个生态系统（对我们的渔业有利或有害）之外，某些浮游生物还可以对我们的海洋产生直接影响：有害藻华（HAB）会使水域有毒。预测未来海洋取决于对小规模生物物理过程的理解。
