In 2015, the Agreement on the Conservation of Cetaceans of the Black Sea, Mediterranean Sea and Contiguous Atlantic Area (ACCOBAMS) commissioned the first overview of the noise hotspots in the Agreement Area, which made an inventory of anthropogenic noise-producing activities and identified and mapped the location of such activities.

At the Seventh Meeting of ACCOBAMS Parties (5-8 November 2019 in Istanbul, Turkey), Parties reaffirmed the recognition that cetaceans, other marine mammals and fish species are vulnerable to noise disturbances and adopted in its Work Programme and Budget for the Triennium 2020-2022 (Resolution 7.6) a plan to revise the impulsive noise hotspots maps of the ACCOBAMS Area.

Related to this effort, it is worth recalling the UNEP/MAP Ecosystem Approach Process (EcAP) aimed at managing human activities with a view to manage land, water and living resources to conserve natural marine heritage and protecting vital ecosystem services so as to reach good environmental status, as noted in ACCOBAMS Resolution 6.12 “Implementation of the EU Marine Strategy Framework Directive (MSFD) and Relevant Ecosystem Approach Process (EcAP). To reach these goals, Contracting Parties to UNEP/MAP adopted Decision IG.22/7 “Integrated Monitoring and Assessment Programme of the Mediterranean Sea and Coast and Related Assessment Criteria” where impulsive noise represents an important topic for the monitoring and assessment processes.

In this context, the ACCOBAMS Secretariat commissioned experts on anthropogenic underwater noise to carry out an update of the first overview hotspots report. The aim of the review is to, amongst others, identify location, timing, frequency range, source type and to produce knowledge on the spatial extent of impulsive underwater noise in the ACCOBAMS Area. The objective of the updated report is to serve as a guide for future discussions about effective management linked to the impact of underwater noise on Cetaceans. The success of this endeavour is contingent on the support of all relevant stakeholders, which includes both governmental and non-governmental entities.

With this in mind the ACCOBAMS Secretariat is seeking your collaboration to collect available data, ranging from the types of activities, start and end date, frequency range, to source level and location of the relevant noise activity.
Detailed overview of the information required in the framework of this initiative.  

Kindly provide any relevant information by the 30th of July 2021 to the ACCOBAMS Secretariat ( and
