In this study, authors introduce the results from three different bottom mounted systems, DWDM, AWAC and DL2, installed in the same offshore area within 20m horizontal distance where wave conditions are almost constant, all using acoustic techniques in combination with pressure. The detail implementation is different in each system and the purpose is to analyze how the differences impact the characteristics of the observed wave spectra. Significant wave heights and periods obtained by each type of wave gauge showed good agreement during the test term, in both high wave conditions with significant wave heights bigger than 6m and low wave conditions with wave heights lower than 0.5m. Nevertheless, in the high frequency component wave expression, AWAC results slightly differs to the DWDM and DL2 results, for AWAC wave data analysis is based on the seabed pressure fluctuation, while DWDM and DL2 wave data analysis is based on direct acoustic water surface movement.
