Description parameter
The results obtained by Romacosa et al. (2017) contribute to the enrichment of the little existing information for this criterion of D11 in the Azores. The above study showed that the monthly average levels of noise, in the 3 seamounts assessed, varied between 90.3 dB re 1 ?Pa (Azores) and 1...

Description criteria
As stated in the report of the first cycle of the MSFD, delivered by the Azores sub-region, ?there is no information on noise levels in the Azores and its impact on animals?, which makes it possible to assess this criterion. An assessment of the frequency or intensity of human activities generati...
Despite the progress made in collecting information for the assessment of Good Environmental Status (GES) for this criterion, it is not yet possible to do so. Additional measures (such as the implementation of monitoring programmes to measure noise over time and in various areas representing diff...

In the first evaluation of this descriptor for the subdivision of the Azores, it was described that the existing information on marine noise was very limited, whether at the level of environmental noise monitoring, or at the level of the recording of anthropogenic activities producing impulse noi...

Between 2012 and 2017, the available acoustic data were collected on an ad hoc basis in the context of environmental impact assessments or local environmental impact assessments (e.g. the BIOMOORE project in the submarine catchment, Atlantis and Gorringe), but do not allow for a quantitative eval...
