Metadata: 2010, Aspect Land and Hydrographic Surveys, North West Lewis Wave Farm, Site Investigation Survey - Siadar to Bragar
Abstract:
On the instructions of Aquamarine Power Ltd, multibeam bathymetric and sub bottom profiling surveys were conducted on the west coast of the Isle of Lewis between 18th August and 2nd September 2010. The survey was to inform planning for the development of a wave energy project in the area.

| Internal code | Internally assigned metadata identifier | 5067 |
| 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, Aspect Land and Hydrographic Surveys, North West Lewis Wave Farm, Site Investigation Survey - Siadar to Bragar |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | 2010, Aspect Land and Hydrographic Surveys, North West Lewis Wave Farm, Site Investigation Survey - Siadar to Bragar |
| 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. | 93aee5e0-9003-4b79-9a5a-03ff4aa330df |
| Resource Identifier | This is the code assigned by the data owner. | a4655 |
| 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. | EM3002 - Kongsberg SIS software was used to control the MBES system during the data gathering phase. Data was simultaneously logged in Kongsberg SIS and HYPACK HYSWEEP software to ensure data redundancy were a computer to fail. R2Sonic 2024 – The Sonic 2024 was controlled via the Sonic Control 2000 program. Data was logged in Hypack during the data gathering phase. After data gathering all data was post processed in HYPACK MBMax where the following stages of processing were undertaken: ß Navigation data was processed. ß Motion Sensor data was examined and edited as required. ß Automatic filtering of the data was carried out. ß Individual lines of MBES sounding data were manually edited. ß Processed files were loaded into Fledermaus visualisation and editing software and fully quality assured before being unloaded back to Hypack. ß The data was gridded at an appropriate post spacing for the scale of plot requested by the client. This was exported to AutoCAD for presentation. ß The data was contoured at 1m intervals in Hypack and exported to AutoCAD. ß X,Y, Z, files at 0.5m post spacing were generated and exported in Hypack. These higher density data files will be rendered to the client in ASCII X,Y,Z format. Data was then transferred to Fledermaus for quality control and preparation of 3D visualisations. The SEG-Y data gathered by the Edgetech 3100P 2-10KHz sub bottom profiler was processed in Chesapeake SonarWiz.MAP software. The following stages were undertaken: ß SEG-Y data was imported to the software. ß The Gain and Time Variable Gain settings were adjusted to ensure that the best possible picture of the sub bottom data was available to the user. ß Each individual horizon was digitised including: o Surface o Sediment horizon 1 o Sediment Horizon 2 o Isolated Reflectors - Point Hyperbolae sonar returns within the sediment o Rockhead / Glacial Till ß Each horizon was referenced to the Multibeam Bathymetry to ensure a coherent record. ß Individual horizons were exported to McCarthy Taylor Systems LSS (3D modelling software) where it was gridded, contoured and prepared for export to AutoCAD. ß Drawing files prepared in AutoCAD to represent the deliverables requested by the client. ß SEG-Y data was saved to DVD as requested and rendered to the client. |
