Sampling regions are displayed in Figure 3. Values are means ± SD (Standard Deviation). When the standard deviation is less than 0.5, it is recorded as 0. The ratio of riblet length-width and depth-spacing is the ratio of two mean values and there has no SD. N/A means that the scales are smooth without riblets.
