Harbour porpoise surveys in Rockabill to Dalkey Island SAC, 2021
In order to contribute to the Department Housing, Local Government & Heritage (DHLGH) site management and surveillance, visual monitoring of harbour porpoises was carried out in Rockabill to Dalkey Island SAC during the summer of 2021. This was the third dedicated line transect survey of harbour porpoises within this SAC which enabled ongoing trends in summer density estimates to be explored. The objectives of the survey in 2021 were to:
i) derive updated summer density and population estimates for harbour porpoises within the Rockabill to Dalkey Island SAC using robust sampling methods for small cetacean density/population estimation;
ii) estimate associated Coefficients of Variation and 95% Confidence Intervals

The route of the survey vessel were stored on Garmin handheld GPS. Map files from each survey were downloaded using Garmin MapSource® software and saved as a text file. These data were then used to create ArcView (Version 9) shape files of the survey effort points, tracks, and location of all sightings recorded during each survey.
Maps of the study area and associated survey data were created in Irish Grid (TM65_Irish Grid) with ArcMap 10.2 while maps of the prescribed survey area, survey track-lines and coordinates were obtained from DHLGH. 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.
