Dataset description
Baseline excess level of noise
Data modelled into 0.4 km x 0.4 km grid.
Baseline excess sound pressure levels at one 1/3 octave band of 125 Hz exceeded at least 50% of the time in the full water column 2018, normalized.
Only baseline excess level included data is directly providing information on the pressure, normalized
Measured and modelled acoustic data is provided as Sound Pressure Level (SPL). The time period for the data is annual values for year 2018. The selected depth interval is 0 m – bottom to represent the ambient underwater noise in the whole water column.
The data were normalized setting level 0 at 92 db re 1µPa and level 1 at 127 db re 1µPa.
