The aim of this survey was to gather detailed information on reef habitats and their associated communities in the northern part of the Pen Llyn a'r Sarnau cSAC and to provide a photographic and video record of the habitats and communities surveyed. The geographic coverage included The North Pen Llyn coast, and concentrated on the section between Penrhyn Mawr and Porth Dinllaen. Surveys took place over a period between the 18th and the 22nd of July 1998.

| 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. | 4f4c4942-4343-5764-6473-313131393234 |
| Resource Identifier | This is the code assigned by the data owner. | 111924 |
| 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 | 1998-07-18 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 1998-07-22 |
| Vertical extent (min) | A positive or negative decimal number, for example, the shallowest depth recorded if subtidal, or, if intertidal, the lowest point recorded. | -2 |
| Vertical extent (max) | A positive or negative decimal number, for example, the deepest depth recorded if subtidal, or, if intertidal, the highest point recorded. | -37 |
| 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::Sea Level |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | inapplicable |

| Abstract | The abstract provides a clear and brief statement of the content of the resource. | The aim of this survey was to gather detailed information on reef habitats and their associated communities in the northern part of the Pen Llyn a'r Sarnau cSAC and to provide a photographic and video record of the habitats and communities surveyed. The geographic coverage included The North Pen Llyn coast, and concentrated on the section between Penrhyn Mawr and Porth Dinllaen. Surveys took place over a period between the 18th and the 22nd of July 1998. |
| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | A total of 18 sites were surveyed, 16 of which corresponded to a list of 20 sites drawn up by CCW prior to survey. Bad weather resulted in the abandonment of offshore survey so the other two sites surveyed were in the shelter of Porth Dinllaen bay. For each site, descriptions of habitats and communities encountered were obtained by divers using standard MNCR techniques. A variety of biotope and species photographs were taken and a video was taken at each site. Confidence in this dataset is high. |
