Metadata: 2015, CEFAS, Zone 1 - Moray Firth, Underwater Noise Modelling - Marine Mammals
Abstract:
An assessment of the noise levels which may be generated during the construction of the MORL offshore wind farm (Project 1) in the Moray Firth was carried out by CEFAS on behalf of Moray Offshore Renewables Ltd. This data series contains reports and data files, in various formats, of this assessment. Since the Environmental Statement (ES), 2012, was completed, a more detailed assessment of the engineering requirements for the piling operation has been carried out. This includes the hammer energies of noise on marine mammals at the site in light of this new information, in the context of the predictions made previously for the ES. The work presented takes into account more detailed site investigations and updated pile drivability assessment and engineering requirements. This updated underwater noise assessment is based on realistic expected worst case scenarios that have reduced significantly from those outlined in the ES. This document will highlight differences will highlight differences between this assessment and the ES and place them into context.

| 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. | 2015, CEFAS, Zone 1 - Moray Firth, Underwater Noise Modelling - Marine Mammals |
| 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. | 1c3a7be7-5ee0-4e84-b3bf-3405588dd442 |
| Resource Identifier | This is the code assigned by the data owner. | CES-359 |
| 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 | 2015-05-19 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2016-01-15 |
| 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. | Source levels of impact piling were modelled based on hammer energy profiles for five possible piling scenarios (most likely and highest expected scenarios for the three soil profiles best represented within the development area). These source levels were then input into an acoustic propagation model â?? which took into account sediment, bathymetry and water column properties at the site â?? to produce noise maps of received levels throughout the Moray Firth. These predictions were combined with noise exposure thresholds for marine mammals (harbor porpoise, bottlenose dolphins, and grey and harbor seals) obtained from the peer-reviewed literature. Effect zones were then mapped for temporary and permanent auditory impairment. |
