Metadata: 2015, EGS, Blyth Demonstration Site, Detailed Geophysical Survey
Abstract:
In June 2015, EDF Energy, Renewables (EDF) contracted EGS International Ltd (EGSi) to undertake a pre-construction geophysical, bathymetric and Annex I habitat survey within the Blyth Offshore Demonstrator Site. The objective of the geophysical survey was: “to act as reconnaissance survey to determine preferred areas for the planned export cable, to re-survey the 2010 and 2011 survey areas in order to determine changes in sediment thickness/laying and to further confirm depth to rockhead in order to assist foundation design and cable routing”. Geophysical operations were undertaken using a high-frequency multibeam system (MBES), side-scan sonar (SSS) system, two different sub-bottom profilers (SBP), one magnetometer (MAG) and an Ultra Short Baseline (USBL) system to be used in conjunction with the SSS. A modified Day grab and a MOD 4 shallow camera system were used for the Annex 1 survey.

| Internal code | Internally assigned metadata identifier | 19414 |
| 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, EGS, Blyth Demonstration Site, Detailed Geophysical Survey |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Detailed Geophysical 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. | d29625bc-4e3a-4942-bf06-9718cf37c572 |
| Resource Identifier | This is the code assigned by the data owner. | TCE-106 |
| 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 | 2015-06-12 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2015-06-27 |
| 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. | The objectives of this survey to accomplish these aims are, therefore, to: • Acquire bathymetric data with 100% coverage that conforms to International Hydrographic Office S44 Standard Order 1a surveys within the pre-defined survey area. This is to attain sea bed depth, topography and to identify any impediments to the installation of WTGs or subsea cables. • Acquire side scan sonar data with 200% coverage of the seafloor. This is to assess the morphology of the seabed, as well as identify impediments to the installation of WTGs or subsea cables. A magnetometer was interfaced with side scan sonar. • Acquire shallow geophysical data to ascertain the sub bottom geology up to 10-15m below the seabed. • Acquire ground truthing of potential Annex 1 habitats from visual methods such as drop down camera, video transects and grab samples. |
