SC Monitoring Program Noise Norbert Häubner norbert.haubner@havochvatten.se
Revised proposal for a regional monitoring sub-program of continuous noise Purpose Quantify the pressure of continuous sound in the HELCOM region Aim To determine the sound pressure level in the Baltic Sea through standardized and coordinated activities by Member States Minor monitoring at prioritized locations and automized runs of soundscape model 2014 2015 2016 2017 2018 2019 ? Post-monitoring analyses, e.g. optimization of number and location of rigs vs. gain of results
Current monitoring A regional coordination is necessary for an cost effective and quality controlled monitoring program. Status of the acoustic measurements in HELCOM countries during 2014 – 2017 “ ” measurements at one or more locations Year Denmark Germany Poland Estonia Finland Sweden Lithuania Latvia Russia 2014 - - - 2015 - - - - - 2016 - - - 2017 - - -
Current monitoring • National monitoring by 6 of 9 member states (no regional coordination) • Standards of monitoring and signal processing already developed • Infrastructure for a regional data sharing platform and visualization tool exist after the BIAS project.
Regional monitoring sub-program Minor monitoring – every year 1. Measurements at prioritized locations - performed by Member States. 2. Maps produced by a soundscape model - performed by appointed party. 3. Soundscape maps combined with measurements in a visualization tool - performed by appointed party.
Regional monitoring sub-program Major monitoring – when needed 1. Need for extended monitoring efforts is based on the difference between yearly observed and modelled results, or by the need for specific actions or results dictated by HELCOM processes. 2. Purpose to calibrate the soundscape model- performed by Member States. 3. Optimization of number and locations of sensors vs. gain of results - performed by appointed party.

Current Soundscape planning tool
Emergence maps of traffic noise above natural sounds The map show the areas where the sound pressure level of anthropogenic noise is above natural (wind and wave) sound – 50 % of the time. The data represents sound pressure level for the 125 Hz 1/3 octave band and is an average over the full water column.
Data arrangements Considered necessary: - Agreements on a responsible S&C caretaker of the data sharing platform (draft caretaking agreement). - Monitor the soundscape planning tool. - Manage administration and quality control. ? Other data demands such as AISA, VMS, wind, sound speed, need to be handled .
