Metadata: 2016, Subacoustech, Dudgeon, Comparison of measured and modelled noise levels during installation of monopiles
Abstract:
Construction began at the Dudgeon Offshore Wind Farm with the installation of monopile foundations during March 2016. The noise levels from impact piling operations were measured and reported by Gardline Environmental Ltd (2016). Measurements were taken at two locations from the piling operations at ranges of 750 m and 4 km using Autonomous Recording Units (ARU). Transmission Loss data was calculated using the RAMGeo acoustic model in order to calculate source levels and impact ranges, which were then compared against predictive modelling undertaken by Subacoustech Environmental before construction. Subacoustech Environmental have been asked to comment on how the previous modelling and the measurement data compare. This technical note presents a comparison between the previous modelling and measured data as well as providing information on extrapolating the results for a worst case piling hammer blow energy of 3000 kJ. At the time of writing, Subacoustech Environmental have not had visibility of the final measurement report and as such this report is not intended to provide a validation of the measurements or measurement methodology.

| 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. | 2016, Subacoustech, Dudgeon, Comparison of measured and modelled noise levels during installation of monopiles |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Comparison of measured and modelled noise levels during installation of monopiles |
| 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. | 06a69fa1-ba29-43ef-82a3-447ac982f7e1 |
| Resource Identifier | This is the code assigned by the data owner. | TCE-319 |
| 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 | 2016-06-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2016-06-30 |
| 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 |
