Metadata: 2012, Wessex Archaeology, Gwynt y Mor, Archaeological Assessment of Geophysical Data
Abstract:
Wessex Archaeology was commissioned by RWE npower Renewables to carry out an archaeological assessment of geophysical data acquired by Osiris Projects. This assessment included interpretation of sidescan sonar, magnetic and multibeam bathymetry datasets covering the proposed Gwynt y Môr offshore wind farm off the north coast of Wales. This report outlines methods used for data acquisition and interpretation in conjunction with the results of the archaeological assessment of the geophysical datasets. The study area covered by this assessment includes the east and west inter-array cable routes and also the export cable route. A total of 109 anomalies were identified during the course of the archaeological assessment, although these tended to be small and of uncertain origin. Limited mitigation in the form of ongoing monitoring during construction is advised rather than exclusion zones.

| Internal code | Internally assigned metadata identifier | 19076 |
| 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. | 2012, Wessex Archaeology, Gwynt y Mor, Archaeological Assessment of Geophysical Data |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Archaeological Assessment of Geophysical Data |
| 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. | 37bb0057-99a1-470e-b840-387e401c9795 |
| Resource Identifier | This is the code assigned by the data owner. | TCE-616 |
| 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 | 2012-07-30 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2012-07-30 |
| 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'. | asNeeded |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | WA carried out an archaeological assessment of marine geophysical data acquired by Osiris Projects. Sidescan sonar, multibeam bathymetry and marine magnetometer datasets were processed for archaeology. The geophysical data were assessed for quality and were generally rated as ‘Good’ using the following criteria: Data which are clear and unaffected by weather conditions or sea state. The dataset is suitable for the interpretation of standing and partially buried metal wrecks and their character and associated debris field. These data also provide the highest chance of identifying wooden wrecks and debris. |
