It includes the number of egg casings found from each species that has been identified in the process of the examination of the casings. The species found include Small-spotted catshark (Scyliorhinus canicular), Thornback ray (Raja clavata), Small-eyed ray (Raja microocellata), Blonde ray (Raja brachyura), Spotted ray (Raja montagui), Undulate ray (Raja undulata) and Cuckoo ray (Leucoraja naevus). Geographic Coverage: The geographic extent and coverage include the described transects on the following beaches on the coast of Wexford, Cahore South Beach, Morris Castle Beach, Curracloe beach, Old Bawn Beach, Ballinoulart Bay Beach, Askingarran Lower Bay Beach, Ballinoulart Bay Beach and Fodagh Bay Beach. Temporal Coverage: 25th of April to the 21st of July 2021 Species Groups recorded: cartilagenous fish (Chondricht Dataset Status: Complete Additional Information: For additional information about this data the website www.therayproject.org can be reviewed or one can contact maya@therayproject.org or research@therayproject.org via email. The data was originally collected to establish what species of ray and skate are still present off the coast of Ireland specifically Wexford. The data collected in this study also has the potential to lead to thorough searches being conducted all around the Irish coast along with further research on Elasmobranchs specific breeding habits, depending on the species found.

A spot height may be expressed as AOD for "above ordnance datum". Usually mean sea level (MSL) is used for the datum. Malin Ordnance Datum Derivation of vertical height or depth (in metres) In the Republic of Ireland, OD for the Ordnance Survey of Ireland is Malin Ordnance Datum: the Mean Sea Level (MSL) at Portmoor Pier, Malin Head, County Donegal, between 1960 and 1969. 5731 EPSG Projection 5731 - Malin Head height Derivation of Altitude OD based on Mean Sea Level, Malin Head 1960-1969 CSV, Excel RFC 1480, Office 2010 Barry O'Neill National Biodiversity Data Centre Data Manager +353-51-306240 Beechfield house, Carriganore WIT West Campus Waterford County Waterford X91 PE03 Ireland info@biodiversityireland.ie http://www.biodiversityireland.ie/ http://maps.biodiversityireland.ie/Dataset/361 text/html View charts and maps information regarding data View data https://maps.biodiversityireland.ie/Dataset/Download?datasetId=361 text/csv Download as CSV (zipped) Download as CSV (zipped) INSPIRE Data Specification on Species distribution INSPIRE Data Specifications v3.0 2013-12-10 The INSPIRE Directive or INSPIRE lays down a general framework for a Spatial Data Infrastructure (SDI) for the purposes of European Community environmental policies and policies or activities which may have an impact on the environment. false COMMISSION REGULATION (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services INSPIRE Interoperability Regulation 2010-12-08 Level of conformance with the COMMISSION REGULATION (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services false The same methodology and search effort was followed during each survey. All casings stored for 24-hour water soakage were labelled so as to avoid confusion and ensure accuracy. The process of identification was completed with the use of a widely accepted and utilised identification key sourced from Shark Trust. The same process was used for each egg casing and a photograph was taken for certainty of correct species identification. All calculations were checked by two members for accurate records of species numbers. Data Capture Method: All survey sites were located on beaches along the coast of Wexford. The methodology conducted involved following two transect lines along the site. The first line is located 1m away from the present embryonic dunes and the second is located along the upper strand line. Egg casings are collected approximately 3 metres either side of the transect lines. This ensures egg casings present throughout the beach are collected in a similar manner each collection. The egg casings then need to be soaked in water for 24hrs before attempting to identify them. Separating the prominent species, then each egg casing is placed into a right-angle ruler on a white background. A photo is taken whilst species identification takes place by studying the size, presence of keel and presence of attachments of each casing. Once all egg casings have been identified and divided, the average size is recorded, and all information is uploaded to the egg hunt form. Data Capture Purpose: The data was originally collected to establish what species of ray and skate are still present off the coast of Ireland specifically Wexford. The data collected in this study also has the potential to lead to thorough searches being conducted all around the Irish coast along with further research on Elasmobranchs specific breeding habits, depending on the species found. Original Format: The data was stored in a pdf survey record sheet and excel document.
