This project will show how novel sensor systems and autonomous platforms can produce a step change in understanding of sea-bed hugging flows called turbidity currents, which are the volumetrically most important sediment transport process on our planet. Turbidity currents can travel at up to 20 m/s for hundreds of kilometres, and they pose a major hazard to seafloor pipelines, and telecommunication cable networks that carry > 95% of global data traffic (including internet and financial markets). A single turbidity current can sometimes carry ten times the annual sediment flux from all the World's rivers combined. Turbidity currents also form the largest sediment accumulations on Earth, which contain major oil and gas reservoirs. They also transfer and sequester globally significant amounts of organic carbon, and supply nutrients that control deep-sea ecosystem functioning and diversity.

该项目将展示新型传感器系统和自主平台如何在理解海底拥抱流（称为浊流）方面产生一个步骤性变化，浊流是我们星球上体积上最重要的沉积物运输过程。湍流可以以高达20米/秒的速度行进数百公里，对海底管道和承载全球95%以上数据流量（包括互联网和金融市场）的电信电缆网络构成重大危险。一条浊流有时携带的泥沙量是世界上所有河流年泥沙量总和的十倍。湍流还形成了地球上最大的沉积物堆积，其中包含主要的石油和天然气储藏。它们还在全球转移和隔离大量有机碳，并提供控制深海生态系统功能和多样性的营养物质。
