Measuring the erosive force of infragravity waves with ADCPs

Top panel: Infragravity wave height measured by the Signature1000 ADCPs at 14 m (blue) and 8 m (red) depth during the five-month campaign. The infragravity wave height is higher at the shallower frame, indicating a growth of the infragravity waves. Bottom panel: Wave energy spectrum during the five-month campaign. The horizontal red lines indicate the infragravity frequency band. Energy at frequencies > 0.04 Hz is related to wind-generated waves.
