Underwater sound emissions were modelled for a number of single sound sources (piles) within Creyke Beck A and Creyke Beck B. In addition, multiple concurrent sound sources were also modelled. This study was undertaken to feed into the Dogger Bank Creyke Beck Environmental Impact Assessment (EIA) process and to inform the Environmental Statement (ES).

The energy flux model has been implemented, with the frequency-dependent absorption formula of Thorpe (1967), with the effect of surface scattering included, and with averaged seabed properties over the region (Hamilton 1980), using the General Bathymetric Chart of the Oceans (GEBCO) Digital Atlas bathymetry data over an area of approximately 180km by 180km. https://www.marinedataexchange.co.uk/details/2493/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site.
