The method of semi-quantitative evaluation of nodule resource estimation using root mean square (RMS) backscatter amplitude gain values from a multibeam echosounding system is presented. The pseudo sidescan images provide additional information about the nature of the seafloor. A comparison of nodule abundance values with the sidescan image show that the light gray patches show high manganese abundance values where as the dark tones on the sidescan images correspond to low abundance values.
