Single platform line-transect surveys were carried out according to a standardised design across six days between June and September. Distance sampling was used to produce a detection function based on the observed distribution of harbour porpoise sightings. Abundance estimates were calculated using the survey day as the sample and sightings as the observation for 1) each survey day, 2) stratified by sea state and 3) for all surveys combined Harbour porpoise monitoring in Roaringwater Bay and Islands SAC National Parks and Wildlife Service Department of Housing, Local Government and Heritage Ecological Data Manager +353-1-8882000 n/a National Parks and Wildlife Service 90 North King Street Dublin 7 D07 N7CV Ireland datadelivery@housing.gov.ie Species distribution GEMET - INSPIRE themes, version 1.0 GEMET 2008-12-05 biota, biodiversity, marine fauna, cetacean GEMET - Concepts, version 4.2.3 2021-12-06 National Parks and Wildlife Service, NPWS, marine, mammal, biodiversity National Parks and Wildlife Service NPWS 2012-07-20 Ireland ISO 3166 ISO Country List 2008-12-13 http://creativecommons.org/licenses/by/4.0/ http://creativecommons.org/licenses/by/4.0/ Copyright Government of Ireland.

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 Metres Derivation of Altitude OD based on Mean Sea Level, Malin Head 1960-1969 Esri shapefile v10+ National Parks and Wildlife Service Department of Housing, Local Government and Heritage Ecological Data Manager +353-1-8882000 n/a National Parks and Wildlife Service 90 North King Street Dublin 7 D07 N7CV Ireland datadelivery@housing.gov.ie.ie https://www.npws.ie/sites/default/files/general/HPRB20.zip zip Dataset Harbour porpoise surveys in Roaringwater Bay and Islands SAC, 2020 dataset published on NPWS website INSPIRE Data Specification on Provide Spatial Data Theme keyword INSPIRE Data Specifications v3.0 2011-06-15 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 Data concerning transects, effort, sightings, abundance and density were stored in a single MS Access database, which was queried and processed via GIS to produce sighting distribution maps.
