dc.description.abstract	Estimates are presented of the local noise generated at infrasonic frequencies by turbulent water flowing in the vicinity of hydrophones used for measurements of ambient noise in the sea. Three situations are discussed: a hydrophone held between the surface and the bottom with water streaming past it; a hydrophone resting on the bottom with a turbulent boundary layer flow above it; and a neutrally buoyant hydrophone floating with the mean speed of the current. The estimates are compared with published data on infrasonic ambient noise, and it is shown that some of the data may be contaminated by flow-noise interference.
