Metadata: Monitoring Tide-Swept Sponge Communities in the Menai Strait, Anglesey and Warrior, Pembrokeshire
Abstract:
Sponges are an important component of benthic communities in temperate waters and can become dominant in suitable conditions. Monitoring takes place at 2 sites within the Menai Strait; Coleg Normal and Nelson's Column and at one site in the Milford Haven (Warrior), Pembrokeshire. Sponge communities in the Menai Strait are dominated by large, relatively fast-growing species, such as Halichondria panicea, Esperiopsis fucorum and Haliclona oculata which thrive in rapid flowing turbid waters. The purpose of this data capture was to record the abundance and 'luxuiousness' of the sponge communities to in order to give an indication of the favourable conservation status of benthic communities within the Special Areas of Conservation (SAC's).

| Internal code | Internally assigned metadata identifier | 8695 |
| 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. | Monitoring Tide-Swept Sponge Communities in the Menai Strait, Anglesey and Warrior, Pembrokeshire |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Monitoring of sponge communities at Warrior, Pembrokeshire, Monitoring of sponges at Nelson's Column, Monitoring of sponge communities at Coleg Normal |
| 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_DS111134 |
| Resource Identifier | This is the code assigned by the data owner. | 4f4c4942-4343-5764-6473-313131313334 |
| 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 | 2004-07-14 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2010-12-31 |
| 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. | Methods at the sites differ due to physical conditions (current and duration of slack water) Transects are marked out at both sites. At Coleg Nomal and Warrior the depth of the sponge crust along with presence/absence of key sponge species is recorded at 0.5m intervals. Where erect sponge species are found within 150mm of the transect the species and height of the sponge is noted as well as the circumference. This is carried out within a 'deep' and 'shallow' zone. At Nelsons Columns a diver swims the length of the transect filming the seabed and conspicuous species and communities. The video is used to describe the habitat and specify species. In addition 0.3x0.3m quadrats are placed at 2m intervals along the transect and the quadrat photographed. Photos are taken and archived as a record of the community and may be analysed in future. Detailed methodologies and descriptions can be found in Marine Monitoring Report 25b (standard operating procedures 3 and 5). Additional monitoring is carried out at the Warrior site (please see the Pembrokeshire Marine SAC reef monitoring metadata entry). |
