Metadata: 2005, CMACS, Rhyl Flats, Benthic Grab Survey
Abstract:
This project examines the pre-construction grab sampling survey that took place during October 2005 at the site of the Rhyl Flats offshore wind farm by CMACS Ltd. This was carried out to provide information concerning the infaunal benthic populations and the sub-tidal sediment types in and around the development area as part of the 2005 baseline program. These surveys will be repeated annually as part of the FEPA monitoring. In conclusion the samples showed inside and on the boundary of the Rhyl Flats development the sediment composition was relatively consistent. The majority of sub-tidal sediments collected were composed of sand of various grades. Most grab stations produced sediment consisting of coarse-medium sand, commonly associated with variable amounts of shell fragments. Some of the more conspicuous fauna were the mask crab at site 2, the sea potato at site 9 and the Lesser sand eel at site 3.

| Other details | ||
| Internal code | Internally assigned metadata identifier | 31432 |
| 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. | 2005, CMACS, Rhyl Flats, Benthic Grab Survey |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Benthic Grab 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. | c228cd15-be60-42a3-aed2-0aa2b4fa28aa |
| Resource Identifier | This is the code assigned by the data owner. | TCE-1846 |
| 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 | 2005-09-07 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2005-10-02 |
| 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 pre-construction monitoring survey was conducted using the research vessel RV ‘Aquadynamic’ operating out of Conwy marina (see Figure. 2). A total of 27 sites were sampled over a 3 day period returning to berth daily, the first stations being visited on the 7th and 9th of September. Poor weather and rough sea conditions precluded the immediate completion of the survey and the remaining sites were sampled and completed on the 3rd October. |
