Metadata: 2014, ESG, Burbo Bank Extension, Topographic and Ground Penetrating Radar Survey
Abstract:
In October 2013 Environmental Scientifics Group (ESG) were commissioned by Dong Energy UK (DONG) to conduct an intertidal geophysical survey over an area of foreshore at Rhyl in Denbighshire. The area to be surveyed is the proposed cable landing point from an extension to the existing Burbo Bank Offshore Windfarm site. A detailed specification was provided which stated the objective of the investigation was as follows: 1. Detect Potential UXO’s 2. Provide Topography for the entire investigation area 3. Provide sub-bottom data This will be used to assist with the design, consenting and construction of the proposed export cable route. The scope of work for the intertidal operations, specified the following: 1. Multi-sensor magnetometer survey 2. RTK GPS Survey 3. Seismic refraction survey of the centreline of the proposed cable route. The survey was carried out in accordance with the specification and works were conducted between 27 November 2013 and 13 December 2013.

| Internal code | Internally assigned metadata identifier | 18957 |
| 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. | 2014, ESG, Burbo Bank Extension, Topographic and Ground Penetrating Radar Survey |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Topographic and Ground Penetrating Radar 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. | 063f7e00-dffc-49de-9031-f27924d77e4d |
| Resource Identifier | This is the code assigned by the data owner. | TCE-227 |
| 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 |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | A combined plot of the utilities location survey results with identified GPR anomalies is presented in Drawing No. L4205-14Utilitiesr0 Enclosure D at a scale of 1:500 and PDF L4205-14_U01-27 Enclosure D. Some topographical features are included for purposes of orientation. The plot is presented both in PDF format and also as an original CAD drawing. It is recommended that the CAD drawing is manipulated by turning on/off relevant layers for clarity if only a specific portion of the survey data are required for working drawings. The anomalies identified during the GPR survey have been plotted on the drawings and presented in Drawing No. L4205-14Utilitiesr0 Enclosure D at a scale of 1:500 and PDF L4205-14_U01-27 Enclosure D. Depth to anomalies were calculated as a function of the velocity of the transmitted radar pulse, thus the total transmission time taken for the pulse to be reflected and then received at the surface. There are a number of regions in the area surveyed where no data could be collected. This was due to a number of factors including but not limited to uneven terrain, deep standing water and dense vegetation. A plot of the results showing the topographic survey is presented in Drawing No. L4205-14Topographicr0 drawing Enclosure D at a scale of 1:500 and PDF L4205-14_T01 to 27 Enclosure D. The topographic data were exported from the GNSS system and then filtered to ensure all points were of RTK quality. The data sets were reduced to Ordnance Datum (Newlyn). Data were only passed to the ground model where the 3D positional quality was of acceptable precision (RTK Fixed Integer). |
