Description parameter
The spatial assessment of noise at the North Atlantic Ocean Demarcation has been carried out on a rectangular calculating grid in latitude and longitude which fully covers it. The grid has been made in three resolutions: 15?, 5? and 1?. The figures showing the spatial distribution in the 1 'mesh size of the received average noise levels (dB re 1 µPa) in the different stations in 2016 and for the two frequencies concerned (63 and 125 Hz) are available in Document IV of the national report. The average annual values are 94 dB (63 Hz) and 83 (125 Hz). the level of 100 dB is exceeded at 27.2 % of the area of the zone for 63 Hz and at 1.45 % for 125 Hz. The level of 110 dB is exceeded at 1.72 % of the area of the 63 Hz area, and is not more than 125 Hz. The level of 120 dB is more than 0.01 % of the area covered by the demarcation. Although there is no definition of BEB agreed at regional/sub-regional level for this criterion, there are some references to thresholds that can produce effects on marine mammals, including the document prepared by NOAA in 2013, by establishing a double criterion per species

Description criteria
For 63 Hz, observe the highest noise levels in the most easterly area of the Demarcación, with values of 110-120 dB, and in some areas they are more than 120 dB. These values are associated with the connection routes between Fuerteventura and Lanzarote, Fuerteventura, Gran Canarias, and the two connection routes between Gran Canaria and the Port of Santa Cruz de Tenerife. Other areas which have added values are those which connect the port of the Christian Christians to San Sebastián de la Gomera and Santa Cruz de la Palma. They also present values to highlight the route of navigation connecting Africa to the Mediterranean Sea and to the Iberian Peninsula which runs parallel to the African coast and the two routes that cross the sea in the North-South direction, with values of 100-110 dB, with the routes located to the east of Gran Canaria being extended and intensity. Another area which presents values is the one connecting the port of Los Cristianos to San Sebastián de la Gomera. Noise associated with fishing at the overall level of the river basin is not considered to be relevant. There are no significant differences in the levels and distribution of noise between stations. It is perceived that in the summer the levels are intensified in the areas furthest away from the coast, especially on the western route crossing the River Basin District, although this could be caused by a larger reach in the reception of the data during this season. Average noise levels at 125 Hz show lower values than for 63 Hz values less than 10 dB lower

Description overall status
There is no definition of good environmental status agreed at regional/sub-regional level for this criterion. A first preliminary version of the register of impulsive noise generating activities has been developed. This application serves to support the RS.1 sub-programme of impulsive noise to evaluate the RS-IMP indicator (indicator 11.1.1 of Decision 2010/477/EU). A spreadsheet has been created to implement the register of impulsive noise sources using the use of EXCEL (version 2013). In addition, ?macros? have been implemented to automate the tasks and calculations carried out. The spreadsheet has been given different tabs where it can be recorded, stored and evaluated each impulsive noise event. For the calculation of the indicator value, RS-IMP has been considered as relevant activities for the assessment of the indicator where the source level exceeds the thresholds identified in the Guidelines [Dekeling et al., 2014]. This tool has now partially been filled in with data from 2014 and the beginning of 2015. For the time being, a partially filled register has been created and a contract that the Ministry for Ecological Transition will tender in 2019 will be able to specify the following tasks: Development of the appropriate tool Fill in data from March 2015 to date Calculate Indicator Illustrative map generation Support the review of the initial assessment and overall marine strategies Review the initial design of the monitoring programme in light of the new European Commission Decision Advise technicians and leaders on impulsive noise, including possible necessary measures
There is no definition of good environmental status agreed at regional/sub-regional level for this criterion. The estimation of the sound levels received was based on a modelling for the whole area of the Demarcation using maritime traffic density data for 2016 assessed from AIS data supplied by SASEMAR. In the absence of a defined threshold, the percentage of the surface area of the sea basin, in which the threshold values of 100, 110, 120 and 130 dB has been calculated for frequencies of 63 Hz and 125 Hz, so that the area reaching good environmental status can be calculated as soon as the threshold is defined.
