MarinEARS into specifically tailored products, addressing 
the needs of federal and state agencies, industry and public 
interest. 
Marine Explorer and Registry of Sound 
MarinEARS hosts data on underwater noise from more than 
1500 offshore foundations in the German EEZ, 
corresponding to more than 2500 pile driving installations 
and several million pile strokes. This comprehensive data set 
provides an important knowledge base regarding acoustic 
measurements and data on the application of technical noise 
abatement systems. Hence, MarinEARS holds an important 
role in managing piling noise impacts and serves 
the fast, daily access for the construction 
supervision of offshore projects, 
the quality control of data and evaluations, 
the assessment of the efficiency of measures based 
an measurements, 
as basis for setting standards.

Figure 1: MarinEARS provides general information on 
underwater noise data in the context of offshore wind farm 
constructions and offers a data repository containing 
specifically tailored products available for download. 
MarinEARS additionally offers publicly accessible general 
and technical information on underwater noise events 
including their location, date and duration. Moreover, it 
provides information on sound pressure levels as well as on 
Ihe application of noise abatement systems. Available 
information and specifically tailored products can be 
accessed via the Web interface marinears.bsh.de. The 
searchable data repository and exemplary products of 
MarinEARS are shown in Figure 1 and 2 respectively. 
The National Noise Registry 
One of the two criteria elements for Descriptor 11 (energy, 
including underwater noise) that are defined in the EU 
Marine Strategy Framework Directive Commission Decision 
(2017/848/EU) concerns the spatial distribution, temporal 
extent and levels of anthropogenic impulsive sound in water. 
Within the context of the Marine Strategy Framework 
Directive (MSFD) a regional impulsive noise registry for the 
North and Baltic Sea hosted by ICES was established in 
2015 on behalf of OSPAR and HELCOM. Member states 
are obligated to report their national impulsive noise events 
annually to the regional noise registry annually

In the framework of the implementation of the MSFD, 
Germany developed measures to achieve and maintain a 
Good Environmental Status regarding underwater noise 
emissions. These measures include the implementation of a 
national noise registry, which has been operated by BSH 
since 2016. MarinEARS provides the backbone of the 
national noise registry. An important product of MarinEARS 
is the obligatory report to the regional impulsive noise 
registry of North and Baltic Sea. The annual reporting 
compiled in MarinEARS concerns impulsive noise events in 
the German North and Baltic Sea from different sources 
including pile driving, detonations of non-transportable 
UXO’s, naval noise and seismic surveys. The Noise Registry 
is publichy acessible at MarinEARS as shown in Figure 3. 
Possible filter parameters for searching the database include 
the year and type of the impulsive noise event, the 
application of noise abatement systems but also information 
on results from the acoustic measurements of the event 
where available.
