Objectives | The main purpose of this cruise was to continue the preliminary measurements of the turbulence in the boundary layer close to the area bed which were started on RV Sarsia in May-June 1975. The programme was particularly aimed at studying the intermittency in the turbulent momentum fluxes, the Reynolds stresses and other turbulence parameters and to examine their variation with height above the bed for comparison with recently published laboratory work. In addition the response of the sediment to the intense instantaneous stresses was to be examined visually using an underwater television. Velocity profiles using an array of four rotor current meters would allow comparison between the shear stresses calculated from the profiles with the Reynolds stresses. |
