Metadata: 2012, Subacoustech, Zone 1 - Moray Firth, Underwater Noise Study
Abstract:
This Technical Study presents in detail the results of modelling undertaken to provide a prediction of the likely extent of effects on marine fauna associated with underwater noise generated during the construction and operation of the proposed Telford, Stevenson and MacColl offshore wind farms in the MORL Zone and associated offshore transmission infrastructure (OfTI). It also provides a review of the literature relating to underwater noise and its impacts on marine fauna, the various metrics used in assessing impacts and additional details relating to the noise modelling methodology.

| Internal code | Internally assigned metadata identifier | 18683 |
| 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. | 2012, Subacoustech, Zone 1 - Moray Firth, Underwater Noise Study |
| 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. | 4dfb7ef9-885a-48a6-ac10-83ab6af20f3c |
| Resource Identifier | This is the code assigned by the data owner. | CES-364 |
| 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. | series |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2011-11-29 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2012-06-19 |
| Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | urn:ogc:def:uom:EPSG::9001 |
| 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'. | asNeeded |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The general approach to estimating the levels of subsea noise from offshore wind farm developments has been undertaken in two phases. In the first a broad-brush modelling approach has been used to rank order a wide range of offshore wind farm-related sources of underwater noise. This was done using the proprietary Simple Propagation Estimator And Ranking model (SPEAR) developed specifically for the Moray Firth developers (Moray Offshore Renewables Ltd, MORL, and Beatrice Offshore Windfarm Ltd, BOWL). In the main, the information used to validate this model has come from the very substantial database of recordings of various noise sources compiled by Subacoustech Environmental over the last 20 years. The model uses estimates from this database of the typical frequency content, source level and transmission losses associated with each type of noise source. These data have been used to determine the impact of each noise source on the marine environment, by using the estimate of noise level and a suitable criterion for a level above which it will have an effect to estimate the area which is affected by the noise source for each class or species of marine animal. |
