Sea state monitoring based on ship motion measurements onboard an icebreaker in the Antarctic waters

A new wave spectrum resembling procedure is applied to detect the sea state parameters, namely the wave peak period and the significant wave height based on the analysis of heave and pitch motion time series, obtained by on board measurements. The outlined procedure is applied to Laura Bassi oceanog...

Description
Summary:A new wave spectrum resembling procedure is applied to detect the sea state parameters, namely the wave peak period and the significant wave height based on the analysis of heave and pitch motion time series, obtained by on board measurements. The outlined procedure is applied to Laura Bassi oceanographic ship, assumed as reference vessel. Heave and pitch motion time histories are evaluated from the survey of the amplitudes of the vessel motions, starting from different sensors measures collected by a smartphone located on board the vessel. The obtained results were compared with the weather forecast data provided by the global-WAM (GWAM) model.
