Ocean circulation is the product of a myriad of processes operating at an enormous range of space and time scales. These range from basin-scale forcing patterns that drive the large-scale currents, to centimetre-scale turbulence that drives ocean mixing and dissipation. A major focus of recent research has been to quantify the large-scale forcing of the global circulation. However, the small-scale mechanisms of mixing and dissipation, as well as the multi-scale processes responsible for the transfer of energy from large to small scales, are of equal importance in governing ocean circulation and the ocean's role in the climate system. These processes remain poorly understood and, as a consequence, inadequately represented in climate models.

海洋环流是在巨大的空间和时间尺度范围内运作的无数过程的产物。这些范围从驱动大规模海流的盆地规模强迫模式，到驱动海洋混合和消散的厘米级湍流。最近研究的一个主要重点是量化全球环流的大规模强迫。然而，混合和耗散的小尺度机制以及将能量从大尺度转移到小尺度的多尺度过程，在控制海洋环流和海洋在气候系统中的作用方面具有同等重要性。对这些过程的了解仍然很少，因此在气候模型中没有得到充分的体现。
