Dear MARMAM community, We are excited to announce that we will be hosting a workshop at the next European Cetacean Society in Dundee on Tuesday 21 th of April (full day): 21F4: A novel tool for large-scale inter-call interval analysis of mysticete calls : assessing temporal and spatial trends. If you're interested in learning how to quickly analyze the famous inter-call intervals in whale songs on large datasets in a standardized way and ultimately spend more time understanding what these patterns mean for populations and conservation, register now! You can find the daily summary here. Feel free to contact us if you would like to work with the tool on your own dataset during the workshop. See you in Dundee! Flore Samaran, Richard Dréo and Cynthia Barile The study of inter-call intervals (ICI) in mysticete songs (blue and fin whales) can reveal key information about population structure and their temporal distribution over the world. Measuring ICI across thousands of calls is a time-consuming, labor-intensive task that is prone to errors. The aim of this workshop is to introduce new analysis techniques for evaluating IC in mysticete calls across large datasets with the ultimate goal of moving toward a standardized approach for conducting global analyses. The first part of the workshop could be a hands-on session, during which participants can apply the methods to their own pre-prepared datasets or to demonstration datasets provided. This session will allow participants to gain practical experience with the analytical tools, explore the effects of different parameters, and receive guidance on best practices for processing large datasets. The second part of the workshop could consist of a brainstorming session focused on the interpretation and significance of variations in ICI across sites and years. Participants will be encouraged to discuss potential ecological, behavioral, and environmental factors influencing these patterns, as well as to explore ways to standardize analyses and share insights for future large-scale studies. _______________ Dr Flore Samaran Reseracher in underwater bioacoustics ENSTA | Institut Polytechnique de Paris Camps de Brest - 2 rue François Verny - 29806 Brest Cedex 9 - France flore.samaran@ensta.fr<mailto:flore.samaran@ensta.fr>
