The observations for this scenario have been carried out by Rippeth et al (2001} in the Liverpool Bay ROFI on July 5 and 6, 1999 at a position of 53 deg 28.4'N, 3 deg 39.2'W. The dissipation rate measurements were carried out with a FLY shear probe mounted on a free-falling profiler. Sensors for temperature and conductivity attached to the profiler give detailed information on the vertical density distribution during each cast. Nearby, an ADCP was mounted on the bottom, giving information on the vertical velocity structure. Some accompanying CTD casts were made in order to achieve estimates for the horizontal gradients of temperature and salinity. The surface fluxes are calculated externally by means of bulk formulae of Kondo (1975), where the sea surface temperature from measurements (FLY profiler) has been used. The bed roughness has been estimated from near-bed ADCP measurements as z0 = 0.0025 m by means of fits to the law of the wall. The external pressure gradient due to surface slopes is estimated according to a method suggested by Burchard (1999) by means of adjustment to near bed velocity observations. The horizontal salinity and temperature gradients for a typical summer situation are prescribed. The numerical simulations of this scenario have been described in Simpson et al (2002).
