Fig. 7From: Reconstruction of sediment-transport pathways on a modern microtidal coast by a new grain-size trend analysis methodContour maps of grain-size parameters interpolated by kriging over raster maps of the estimation variance. The relatively lighter gray color in each raster map indicates a higher precision of interpolation. The absolute values of the estimation variance are not meaningful because these values depend on the values of the variables and the shapes of the variogramsBack to article page
