Metadata: Skomer Marine Conservation Zone ( MCZ ) - Monitoring of sponge assemblages
Abstract:
In 2015 Skomer Marine Nature Reserve changed designation to Skomer Marine Conservation Zone (MCZ). Skomer Marine Nature Reserve (MNR) was designated in 1990. The sponge communities at Skomer MNR have been identified as rich and diverse with over 80 species. Six are nationally scarce species and eight near the limit of their distribution. Sponges are filter feeders and therefore reliant on water quality which makes them susceptible to changes in sediment deposition. They are therefore useful biotic indicators of changes in suspended sediment and surface sedimentation rates, the cause of which might include dredge spoil dumping. The purpose of this data capture was to: - monitor the sponge assemblages in the MNR; - identify natural and anthropogenic fluctuations, - identify the presence of rare, scarce and edge of range species in the MNR.

| Internal code | Internally assigned metadata identifier | 8554 |
| 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. | Skomer Marine Conservation Zone ( MCZ ) - Monitoring of sponge assemblages |

| 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. | NRW_DS101857 |
| Resource Identifier | This is the code assigned by the data owner. | 4f4c4942-4343-5764-6473-313031383537 |
| 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 | 1993-09-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2011-12-31 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 100 |
| Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | urn:ogc:def:uom:EPSG::9001 |
| 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'. | annually |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Transects: Four fixed transects are located at Thorn Rock. Photographs are taken from fixed positions along the transect using a stereo camera set up on a 50 x 70cm frame. The slides are analysed using a stereo viewer to count the abundance of sponge species and morphology types. Species survey: In 2003 all sponge species identified in 16, 50 x 70cm quadrats. In 2007 no quadrats were used, survey completed in the general vicinity of the 4 transects with all species being identified if possible. Species photographs were taken in the field and samples taken, where necessary, for spicule preparations. Seasonal survey from fixed quadrats: In 2005 15 1m2 quadrats were marked out at 3 sites. The quadrats each consist of 25 cells (20 X 20cm), which are photographed using a digital camera. |
