MMO1097 Modelled mapping of continuous underwater noise generated by activities

asNeeded

These outputs have been prepared by ABP Marine Environmental Research Ltd (ABPmer) on behalf of the Marine Management Organisation (MMO) under project MMO1097Modelled mapping of continuous underwater noise generated by activities. A model was built in ArcGIS to produce indicative spatial data of relative continuous or ambient anthropogenic underwater noise distribution generated by activities in the south marine plan areas. The outputs are based on the 2km x 2km AIS density grid for UK waters (MMO project 1066). The spatiotemporal distribution of human activities were represented using AIS shipping density data, Electronic Monitoring System (EMS) aggregate dredging data and Vessel Monitoring System (VMS) fishing data. Then a simple propagation model was used to represent the propagation of noise from these sources. For further information please refer to the main report. The data is created in WGS84 UTM 30N and re-projected to ETRS89. Caveats: The data should not be used at individual case level but as a high level indicative layer. If using this data please consult the KIM team and the report for a complete list of caveats to consider.
