A maximum fraction of 20% or lower over 1 day of the habitat to be exposed to impulsive noise levels higher than estimated effect range. Data was used for the ordnance explosions, as provided by the Hellenic Navy for the years 2020-2022. Seismic survey data was not adequate for performing the assessment. The percentage of habitat area adversely affected in the MRU for Common dolphin (Delphinus delphis) in year 2020 (22.33%) exceeded the TV of 20%.

A maximum fraction of 10% or lower over 1 year on average of the habitat to be exposed to impulsive noise levels higher than estimated effect range. The maximum percentage of the habitat area adversely affected for all species during all years with data (2020-2023) is set as ProportionValueAchieved.

ThresholdQualitative was not exceeded more than 50% of the time in more than 20% of the assessment area in the 63 Hz third-octave band. Assessment was performed for 2023. The third-octave band centred at 63 Hz was used as a proxy for the assessment of behavioural disturbance. The maximum percentage of the habitat area adversely affected for all species is set as ProportionValueAchieved. This percentage was found to be very sensitive to small LOBE changes (of the order of 1 dB), which can lead to exceedance of the TV of 20%.
