Marine Noise Registry
The UK Marine Noise Registry (MNR) is a database that records the spatial and temporal distribution of loud, low to medium frequency (10Hz – 10kHz) impulsive noise generating activities in UK seas.
Impulsive noise is generated by a range of activities including impact pile driving, explosions and geophysical surveys. Many of these activities may only be carried out under licences granted by a regulatory authority. Other activities, such as those undertaken by the Ministry of Defence, are not licensed. In both cases, data will be submitted to the MNR.
Noise distribution maps for Scotland’s seas are available on MS Maps NMPi showing impulsive noise data for activities taking place from January 2015 as two layers:
- Distribution of impulsive noise events, Total Pulse Block Days (PBD) for 2015-2017 (time-aware)
- Distribution of noise activity type per Block for 2015-2017 (time-aware)
