Metadata: 2014, SMRU Marine, Skerries, Marine Mammal Monitoring
Abstract:
There is a range of monitoring methodologies available for monitoring marine mammals at marine renewable energy sites (Macleod et al. 2011; Sparling et al. 2011). However, the location and scale of the Anglesey Skerries Tidal Array Project site presents a particular set of challenges with respect to collecting marine mammal data. Traditional vessel based line transect surveys do not yield data of sufficient spatial and temporal resolution to fully inform questions of risk relating to a project of this scale nor provide a suitable baseline against which to measure change given the resolution of sampling and the likely natural variation. Additionally vessel based line transect surveys are generally not feasible year round given expected weather conditions and wave climate at such an exposed site. Static PAM methods are a challenge in highly noisy and energetic areas such as tidal sites and only appropriate for echolocating cetaceans and are not suitable for monitoring seals. However, since the development area is just under two kilometres from shore it is also not optimal for shore based vantage point surveys. In order to assess whether shore based data collection methods would be suitable for pre-installation monitoring at the Skerries site, a land-based vantage-point (VP) transect survey trial was implemented to determine if recent advances in vantage point methods and analytical approaches could provide sufficient data to meet the monitoring objectives set out in the EMAMP.

| Internal code | Internally assigned metadata identifier | 19162 |
| 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. | 2014, SMRU Marine, Skerries, Marine Mammal Monitoring |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Marine Mammal Monitoring |
| 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. | 5a388a4b-9921-42c9-8461-aa4f43379351 |
| Resource Identifier | This is the code assigned by the data owner. | TCE-2018 |
| 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 | 2014-05-03 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2014-09-19 |
| 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 vantage points were located on Carmel Head on the Isle of Anglesey, Wales, overlooking the Skerries Islands and the tidal array development site (Figure 1). The two surveyor positions were 20 metres apart. Surveyors rotated between these two positions on different survey days. Twenty three wooden marker poles were placed along the coast line in front of the surveyors to be used as known position reference points in the photo geo-referencing analysis. |
