D11
Introduction of energy,
including underwater noise

2. TSG Noise
The technical working group has defined a number of standards at a conceptual level
These standards are enacted within the systems created/to be created to support D11 at a national and regional level

3. D11C1 – Impulsive Noise
Anthropogenic impulsive sound in water.
for D11C1, the duration per calendar year of impulsive sound sources, their distribution within the year and spatially within the assessment area, and whether the threshold values set have been achieved;

4. D11C1 – Impulsive Noise Registers
NE Atlantic (OSPAR) and Baltic (HELCOM) contracting parties using the Noise Register hosted at ICES
Mediterranean using the ACCOBAMS based register *
*note the ACCOBAMS register is a demonstrator and not using real data at this point in time

5. D11C1 – Noise Registers status
ICES Noise register:
Operational since feb 2016
Data from 7 countries
ACCOBAMS register
Demonstrator operational since feb 2017
Data not yet provided

6. D11C1 – Data Exchange Format
Based on TG NOISE recommendation
ACCOBAMS has based its initial format on the same, but with fewer of the fields
File Header
(3 fields)
Noise Data ( fields)
Vocabularies
(7 lists)

7. D11C1 – Vocabularies
Using existing controlled lists where available: ISO 3166 Country, SeaDataNet EDMO (Organisation)
New vocab lists built on TSG recommendation and RSC’s experts input i.e. Mitigation measures, Source Event Type

8. Available through OGC WFS (as well as map viewer on portal) Example:
D11C1 – Indicator output
Available through OGC WFS (as well as map viewer on portal)
Example:

9. D11C2 – Continuous Noise
Anthropogenic continuous low-frequency sound in water.
for D11C2, the annual average of the sound level, or other suitable temporal metric agreed at regional or subregional level, per unit area and its spatial distribution within the assessment area, and the extent (%, km2)

10. Regional activity linked to TSG Noise
D11C2 – Continuous noise
Regional activity linked to TSG Noise
RSC’s have active expert groups working
Linked to 3 research projects:
AQUOS and SONIC focussing on noise mitigation from shipping
BIAS (Baltic) has developed standards on acoustic data sharing and noise measurements
