- A nepheloid layer or nepheloid zone is a layer of water in the deep ocean basin, above the ocean floor, that contains significant amounts of suspended sediment. It is from 200 to 1000 m thick. The name comes from Greek: nephos, "cloud". The particles in the layer may come from the upper ocean layers and from stripping the sediments from the ocean floor by currents. Its thickness depends on bottom current velocity and is a result of balance between gravitational settling of particles and turbulence of the current. The formation mechanisms of nepheloid layers may vary, but primarily depend on deep ocean convection. Nepheloid layers can impact the accuracy of instruments when measuring bathymetry as well as affect the types marine life in an area. There are several significant examples of nepheloid layers across the globe, including within the Gulf of Mexico and the Porcupine Bank. (en)
- 霧狀層（Nepheloid layer）是深海中一层含大量悬浮物的海水。该层中的悬浮颗粒可来自上层海水或從海底被剥离出的沉积物。其厚度取决于海底流的速度，颗粒的悬浮是因爲颗粒的重力沉降和水流湍流之间達到平衡，颗粒就會悬浮。 (zh)
