noun
turbidity current
A geological term for a sediment-laden underwater current that moves down a slope due to its higher density.
乱泥流は海底峡谷を通って深海に堆積物を運ぶ。
Turbidity currents carry sediment to the deep sea through submarine canyons.
Compound of 乱 (ran, 'disturbance') + 泥 (dei, 'mud') + 流 (ryū, 'flow'). The term is a direct translation of the English 'turbidity current'.
