Dataset Details - ObSERVE Towed Passive Acoustic Surveys for Cetaceans in the Irish Atlantic Margin
Acoustic detections of Cetaceans made during Passive Acoustic Surveys using towed hydrophone arrays, conducted by SMRU Consulting and the Galway Mayo Institute of Technology as part of the ObSERVE Project 2015 - 2017
To assess the occurrence, distribution and abundance of cetaceans in the Irish Atlantic Margin
Passive Acoustic Monitoring (PAM) using a towed hydrophone array from a vessel (ship/boat) at sea
Irish Atlantic Margin
2015 - 2017
Stored data were reprocessed offline using PAMGuard configured to detect odontocete clicks with energy in the 2 kHz to 150 kHz band. Data were first digitally filtered to remove unwanted noise from the signal. Individual detected clicks were first classified using a classifier that used frequency and time-based parameters from the waveforms of clicks. The PAMGuard displays were carefully reviewed by an analyst to identify the sequences of clicks deemed to be from individuals or groups. The operator assigned a final species group classification to each event (guided by the program’s classification and by their assessment of the characteristics of individual clicks).
Use of the data in any publication is prohibited until 1st May 2019. Any publication post 1st May 2019 should acknowledge the ObSERVE project partners the Department of Communications, Climate Action and Environment and the Department of Culture, Heritage and the Gaeltacht
