Metadata: 2010, Gardline Environmental, Sheringham Shoal Offshore Windfarm, Seabed Intervention UXO Clearance Survey
Abstract:
Gardline Environmental was contracted by SCIRA to provide Seabed Intervention Services including UXO clearance operations on the Sheringham Shoal Windfarm site and export corridors. Target locations were provided by SCIRA from data acquired by previous surveys. The investigations were concentrated on targets identified within 25m of proposed inter-turbine array cables, turbine locations and the exclusion zones related to forthcoming jack-up vessel operations. The vessel OMS Pollux was utilised as the survey platform with surface and sub-surface positioning provided by Gardline Environmental. Specialist UXO services were provided by MACC EOD International with diving operations being performed by Red7 Ltd. ROV operations were carried out by Eriksson Diving Ltd. Field work was carried out between January and April 2010. The survey instrumentation on the OMS Pollux included two Hemisphere VS110 DGPS systems with one system receiving beacon corrections based on the IALA network and the other receiving SBAS corrections. Subsurface positioning was provided by an Applied Acoustics Easytrak system with micro beacons being used to position the divers, ROV and crane hook during lifting operations. A total of 52 targets were investigated over the course of the project. Objects were identified at 36 of these targets. Of these objects, 6 were recovered to deck, 3 were relocated in the field, 1 was disposed of by explosives and the remainder were left in-situ as they did not meet the criteria warranting further action. At 16 of the 52 reported targets, no objects were identified.

| Internal code | Internally assigned metadata identifier | 5356 |
| 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. | 2010, Gardline Environmental, Sheringham Shoal Offshore Windfarm, Seabed Intervention UXO Clearance Survey |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Inspection and clearance of selected targets from UXO survey in the wind farm area and Export Cable routing corridor that interferes with planned infrastructure layout |
| 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. | c379bd6cf95158faac18338147b0be7c |
| Resource Identifier | This is the code assigned by the data owner. | 4829 |
| 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 | 2010-01-05 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2010-04-07 |
| Vertical extent (min) | A positive or negative decimal number, for example, the shallowest depth recorded if subtidal, or, if intertidal, the lowest point recorded. | -24.5 |
| Vertical extent (max) | A positive or negative decimal number, for example, the deepest depth recorded if subtidal, or, if intertidal, the highest point recorded. | -1.5 |
| Vertical extent reference | This descibes the vertical coordinate reference system as referred to in the EPSG register of geodetic parameters. (epsg-registry.org) | Chart Datum at Cromer |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 0.1 |
| Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/resources/uom/gmxUom.xml#m |
| 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 |
