Turbulence measurements of scales as small as two inches have been made in the ocean with hot‐wire equipment which was especially designed for use in sea water. Observations have been made of the variation of the turbulence spectrum over a tidal cycle in the Strait of Juan de Fuca and of the influence of an underwater obstacle in altering the spectral distribution. A preliminary experiment has been carried out to correlate velocity and pressure fluctuations due to turbulence in the ocean. From the work done to date the specifications for a hot‐wire instrument for use in the sea can be outlined. A review of several types of turbulence measuring instruments that have been used in water is included.
