Description criteria |
The impulsive sounds are mainly from explosions. In 2013, 2014, 2015 and 2016, there were 32, 169, 54 and 372 explosions, respectively. Description in HELCOM assessment: http://stateofthebalticsea.helcom.fi/pressures-and-their-status/underwater-sound/#impulsive-sound. |
The assessment results are presented in the national assessment in Chapter 4.4 and in the HELCOM assessment (http://stateofthebalticsea.helcom.fi/pressures-and-their-status/underwater-sound/#continuous-low-frequency-anthropogenic-sound). |
