This project aims to investigate how surface biofilms affect flows at the ocean surface. Great stretches of the ocean surface are covered by an organic microlayer called biofilm. Flows at the ocean surface are a crucial part of climate machinery, and biofilms have profound, largely unexplored effects on these flows. There is no fundamental understanding of how biofilms affect fluid motion. This project aims to use laboratory models and new measurement techniques to study and quantify the impact of biofilms on turbulent transport. Understanding these effects is important in a time of climate change and this knowledge may also help address environmental issues related to spreading of pollutants and flow control at the ocean surface.

该项目旨在研究表面生物膜如何影响海洋表面的流动。大片的海洋表面被一种叫做生物膜的有机微层所覆盖。海洋表面的流动是气候机制的重要组成部分，生物膜对这些流动有着深刻的、基本上未被探索的影响。生物膜如何影响流体运动还没有基本的了解。该项目旨在使用实验室模型和新的测量技术来研究和量化生物膜对湍流传输的影响。了解这些影响在气候变化时期很重要，这方面的知识也可能有助于解决与污染物扩散和海洋表面流动控制有关的环境问题。
