A survey of harbour porpoises (Phocoena phocoena) was carried out within the Blasket Islands candidate Special Area of Conservation (cSAC) to derive density and abundance estimates and carry out static acoustic monitoring. Single platform line-transect surveys were carried out on six days between 16 July and 1 October 2007. Distance …
A visual and Passive Acoustic Monitoring (PAM) survey of harbour porpoises (Phocoena phocoena) was carried out in 2013 at two Special Areas of Conservation (Rockabill to Dalkey Island SAC, Co Dublin and Roaringwater Bay and Islands SAC, Co Cork) in order to derive local density and abundance estimates. Single platform …
A single platform line-transect survey using distance sampling was carried out off the north coast of Ireland on 9 August 2012. Sea conditions were excellent throughout the survey with 100% of survey effort carried out in sea-state ≤3 and 63.5% in sea-state ≤1. A total of 178 km of track-line …
Concurrent visual and acoustic surveys for cetaceans were carried out within three survey blocks along the western seaboard of Ireland (Northwest – Block A, west – Block B and southwest – Block C) to investigate species distribution, relative abundance and absolute abundance where possible. Single platform line-transect surveys were carried …
A visual and acoustic survey of harbour porpoises (Phocoena phocoena) in the Blasket Islands SAC was carried out in 2014 in order to derive local density and abundance estimates. Single platform line-transect surveys were carried out according to a standardised design on six days between June and September 2014, and …
A population assessment of the bottlenose dolphins in the Lower River Shannon candidate SAC was undertaken between July and October 2010. Dolphins were located on each transect. During 12 transects a total of 64 dolphin groups were encountered with 547 individuals recorded. Group sized ranged from 1-50 overall. Lone dolphins …
A visual survey of harbour porpoises (Phocoena phocoena) was carried out in the summer of 2016 within the Rockabill to Dalkey Island SAC, Co Dublin in order to derive local density and abundance estimates. Single platform line-transect surveys were carried out according to a standardised design on four days between …
The Western European Shelf Passive Acoustic Survey is an acoustic survey undertaken by the Fisheries Ecosystems Advisory Services (FEAS) Department of the Marine Institute of Ireland. The WESPAS provides a unique opportunity for surveillance of the summer distribution of cetaceans in shelf water habitats along Ireland’s Atlantic margins which can …
Irish waters represent one of the most important marine habitats for seabirds in Europe and are utilized by a wide range of seabird species. However, the at-sea abundance and distribution of many of the seabird species occurring in Irish waters remains poorly understood. Under the EU Birds Directive, there is …
