Single platform line-transect surveys were carried out according to a standardised design on six days between June and September 2018. Surveys were conducted between 5th June and 24th September 2018. The purpose of this project was to derive local density and abundance estimates for Harbour porpoise in the Blasket Islands SAC.

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/HPBI18.zip zip Dataset Harbour porpoise surveys in the Blasket Islands SAC, 2018 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 The shapefile HPBI18_Species_Survey_1 was created on the 5th June 2018 as part of the 2018 Harbour porpoise surveys in the Blasket Islands SAC. During each transect the position of the survey vessel was tracked continuously through a GPS receiver connected to a laptop computer, while survey effort data including environmental conditions (sea-state, wind strength and direction, glare, etc.) were recorded every 15 minutes using LOGGER software ( IFAW). When a sighting was made the position of the vessel was recorded immediately and the angle of the sighting from the track of the vessel and the estimated radial distance of the sighted animal(s) from the vessel were recorded. These data were communicated to the recorder in the wheelhouse via VHF radio. The angle was recorded to the nearest degree using an angle board attached to the vessel immediately in front of each observer. Accurate distance estimation is important for distance sampling. Measuring sticks (Heinemann 1981) were used by each primary observer to assist in distance estimation. The data was modified to comply with GDPR legislation and open data publication guidelines.
