Metadata: UK Marine Strategy Descriptor 11 ship noise assessment data for 2018 to 2022
Abstract:
Annual median broadband (63 Hz - 4 kHz) sound level data for UK waters for the years 2018-2022 inclusive. Data format is ASCII. These maps underpin the UK Marine Strategy 2024 assessment for Descriptor 11.2 (continuous anthropogenic sound). Images of these maps in PNG format are also provided for reference. A summary table is also included which describes percentages of assessment region areas exceeding sound levels above given decibels.
Data holder:
Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | UK Marine Strategy Descriptor 11 ship noise assessment data for 2018 to 2022 |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | CEFASa7298bfe-ace1-4978-9eb9-c0b601ad25ee |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS22184 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2018 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2022 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Under the UK Marine Strategy, Good Environmental Status for Descriptor 11.2 is defined according to the “spatial distribution, temporal extent and levels of anthropogenic continuous low-frequency sound”. Since the spatial distribution of noise is required, noise mapping must be undertaken in order to assess the indicator. Although field monitoring of continuous sound in support of the Descriptor has been ongoing since 2018, such monitoring only provides data at point locations in the UK EEZ. To produce noise maps of continuous sound, it is necessary to couple this field monitoring at specific locations with spatial models of continuous sound levels. Such models are derived from data on sound sources (e.g. ship movements, wind speed) and the propagation of underwater sound in the environment (which depends on bathymetry, seabed composition, and water column properties). The source levels of wind-generated noise were modelled based on Reeder et al. (2011) using wind speed data sourced from the European Centre for Medium-Range Weather Forecasts (ECMWF) ERA-Interim/ERA-5 global atmospheric reanalysis (ECMWF, 2021). Ship source levels were computed using the JOMOPANS-ECHO model (MacGillivray and de Jong, 2021) and satellite AIS data. The sound propagation was modelled using the energy-flux method (Weston, 1971). Bathymetry data were extracted from EMODNET with 7.5” resolution, temperature and salinity data from the Copernicus Atlantic European North West Shelf Ocean Physics Analysis and Forecast product (0.016° x 0.016°, 33 depth levels, daily mean values) (Copernicus, 2019). Seabed acoustic properties were derived from the Hamilton model (Hamilton, 1987) using EMODNET seabed sediment data. |
