This portal assembles data supplied by contracting parties to OSPAR (North East Atlantic) and HELCOM (Baltic Sea). The data are collated nationally from registers of licenced events such as pile driving, controlled explosions from naval operations and other activities that release energy.
This registry is specifically purposed with supporting OSPAR and HELCOM in providing information that will feed their regional assessments, and in reporting by its contracting parties to MSFD descriptor 11.1.1 (Low and mid frequency impulsive noise).
The impulsive noise reporting format has changed in agreement with HELCOM EN NOISE and OSPAR ICG NOISE. The updated format is now online. Use the 'download reporting format' button on the right hand menu.
