Metadata: 2012, EGS, Walney, November Post-Construction Survey
Abstract:
In November 2012 EGS (International) Ltd was contracted to undertake the second post construction (6 month) survey of the wind farm. The aim of the survey was to identify changes to seabed morphology within the wind farm and along the export cable routes. To meet the requirements of the survey EGS operated a Kongsberg EM3002D high frequency multibeam system and a Klein 3000 dual frequency side-scan sonar (SSS) in conjunction with a USBL system, across each of the proposed WTG’s, substation locations and export cable routes.

| Internal code | Internally assigned metadata identifier | 19688 |
| 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, EGS, Walney, November Post-Construction Survey |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | November Post-Construction Survey |
| 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. | f1937d48-1b9c-414e-8108-43b62ce8ed76 |
| Resource Identifier | This is the code assigned by the data owner. | TCE-2187 |
| 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 | 2012-11-08 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2012-11-29 |
| 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. | Horizontal positioning has been transformed to the UTM-30N projection. C&C Technologies C-Nav DGPSs were used for horizontal positioning and were interfaced into QPS QINSy. The C-Nav 2050 was used as the primary positioning system which was receiving RTK corrections from the base station at the onshore DONG marine-communication tower. The corrections were transmitted via a telemetry link at a frequency of 458.65 MHz. The C-Nav 2000 system was receiving real-time C1 corrections and was used by QINSy for positioning when the CNav 2050 could not receive RTK corrections, mainly to the west of the survey area. |
