Metadata: 2012, EGS, Walney Extension, Export Cable Route Additional Geophysical Survey
Abstract:
In May 2012 EGS (International) Ltd was contracted to undertake a pre-construction geophysical and bathymetric survey of the export cable route of the future Walney Extension (WOW03) windfarm site. The surveyed areas were located 22-30 km north-northwest of Walney Island, UK. Survey operations were carried out in three distinct locations; Block 1 and two separate cable routes String 2 and String 3. The survey was a Part 1 Consent and Environmental survey, data gathered for which is anticipated to lead to consent for grab sampling at the proposed sites. EGS conducted a high-frequency Multibeam Echo Sounder (MBES) bathymetric survey, combined with side-scan sonar (SSS), magnetometer and seismic sub-bottom systems. A pole-mounted Kongsberg HiPAP 351P/5 USBL was used for accurate sub-surface positioning of the towed instruments.

| Resource Identifier | This is the code assigned by the data owner. | TCE-2239 |
| 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 | 2012-05-18 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2012-05-30 |
| 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'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The main equipment spread consisted of a Kongsberg EM3002D MBES, Klein 3000 dual frequency SSS, C-Products C-Boom SBP and Geometrics G882 marine MAG (towed behind the SSS). C&C Technologies C-Nav 2050 DGPS was used for horizontal positioning, in combination with a Kongsberg HiPAP 351P USBL system for the SSS tow fish (interfaced into the QPS QINSy navigation package). Vertical level was LAT (VORF LAT Geoid model), levels were derived by post processing raw GPS data acquired by the Leica 1200 and the C&C Technologies C-Nav units. A 500-metre wide corridor at the String 2 and String 3 cable route sites were surveyed at 50 metre line spacing to obtain 100% survey coverage; Block 1 was surveyed at a 50 metre line spacing to obtain 100% coverage of the area. |
