 note = {Using CTD data obtained on the T/S Kagoshima-maru during 20 hours on December 2-3, 1989 in a triangular area centered at 29-09N, 134-51E (each distance between three tips are 35 miles), the small scale spatial distribution of ocean surface mixed layer depth (MLD) and the vertical heat flux at the bottom of surface mixed layer were examined. Assuming the spatial homogeneousness of internal tide, the contribution of internal tide to MLD defined by sea surface temperature (SST) minus 1.0°C depth, is estimated to ±20m, about 20% of mean MLD. Spatial distribution of MLD corrected by reducing the internal tidal components by least square method has good similarity with temperature distribution at 200m depth, suggesting that MLD distribution is well correlated with two cyclonic small eddies at 200m depth of which radii are 15-40 miles. Vertical velocity component of the current flowing along isopycnal surface at 100m depth is calculated to be 2.2×10^{-3} cm s^{-1} by beta-spiral method using CTD data which does not contain the contribution of internal tide but eddy. Then, vertical heat flux (positive upward) at the bottom of surface mixed layer (100m depth) was estimated to be -78W m^{-2} using mean temperatures at 75 and 100m depth.},
