The purpose of this data capture was to create a dataset to help with an evaluation of the deployment of drop-down video for identifying biotopes. Footage collected as an assessment of using drop-down video as part of a site-orientated monitoring technique. Data was gathered as a result of the development and trial of a remote drop-down video-based monitoring method to measure biotope richness. Data was collected from two sites that presented sufficiently different physical conditions and biological conditions- north Pen Llyn reefs, and Sarn Badrig reef.

| 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. | 4f4c4942-4343-5764-6473-303837313134 |
| Resource Identifier | This is the code assigned by the data owner. | 87114 |
| 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. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 1999-07-08 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 1999-08-05 |
| Vertical extent (max) | A positive or negative decimal number, for example, the deepest depth recorded if subtidal, or, if intertidal, the highest point recorded. | 15 |
| Vertical extent reference | This descibes the vertical coordinate reference system as referred to in the EPSG register of geodetic parameters. (epsg-registry.org) | urn:ogc:def:crs:EPSG:: |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | inapplicable |
| 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 |
| Abstract | The abstract provides a clear and brief statement of the content of the resource. | The purpose of this data capture was to create a dataset to help with an evaluation of the deployment of drop-down video for identifying biotopes. Footage collected as an assessment of using drop-down video as part of a site-orientated monitoring technique. Data was gathered as a result of the development and trial of a remote drop-down video-based monitoring method to measure biotope richness. Data was collected from two sites that presented sufficiently different physical conditions and biological conditions- north Pen Llyn reefs, and Sarn Badrig reef. |
| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The method development and trialling carried out during this survey was a precursor to the across Wales drop-down video monitoring work undertaken in 2004-05. The video was subsequently re-analysed in April 2012 by CALM and the data held in Marine Recorder replaced. Drop-down digital video-based monitoring gear, deployed from a 7.5m aluminium RIB. Species and habitat data entered into Marine Recorder. Data collected for primarily for method validation purposes. See sections 2.1.3 and 3.1.2 of the Marine Monitoring Report. Analysis of the video for it's biological and physical attributes was undertaken by Aquascan Ltd in 1999. The video was subsequently re-analysed in April 2012 by CALM and the data held in Marine Recorder replaced. |
