Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.
PO040: Modelling bioacoustic data to assess the effects of environmental and anthropogenic drivers on the presence and behaviour of cetaceans in an offshore wind farm development area
Alessio MAGLIO, Marine Environment Expert PhD, SINAY
Abstract
The development of offshore wind farms raises concerns about potential impacts on marine biodiversity, particularly cetaceans, whose presence and behaviour can be influenced by both environmental and anthropogenic factors. This study investigates cetacean bioacoustic activity in the planned floating offshore wind farm area off southern Brittany (AO5) prior to construction. Passive acoustic monitoring (PAM) was conducted over a full year using six FPODs and three broadband recorders, resulting in the collection of approximately 250 TB of acoustic data. Detections were classified into harbour porpoises (Phocoena phocoena) and delphinids, with click rates used as indicators of presence and activity. Environmental variables including sea surface temperature (SST), current speed, salinity, phytoplankton biomass (proxy for prey availability), depth, and distance to shore were analysed. Anthropogenic noise was also investigated through variations in sound levels and AIS data. The findings provide critical baseline information on seasonal patterns of cetacean occurrence and behaviour, highlighting environmental drivers and possible short-term responses to human activities. This work supports future environmental impact assessments and mitigation measures to ensure sustainable development of offshore renewable energy while safeguarding marine ecosystems.
