Dear MarMamers, We would like to share an early save-the-date announcement for the 9th International Bio-Logging Science Symposium (BLS9), which will take place October 18-22, 2027 in Sevilla, Spain. Bio- and Physio-logging approaches are widely used in marine mammal research to study behavior, movement ecology, foraging strategies, physiology, energetics, and responses to anthropogenic stressors (e.g., noise, fisheries interactions, and climate change). BLS9 will bring together an international and interdisciplinary community working on the development and application of animal-borne sensors, including many studies focused on marine mammals across diverse environments. The symposium will include sessions relevant to marine mammal science and conservation, such as: * Diving physiology, energetics, and gas dynamics * Behavioral ecology and movement patterns * Responses to disturbance (e.g., sonar, shipping, and other anthropogenic noise) * Climate change impacts and habitat use * Advances in biologging technology and analytical methods While the symposium has strong relevance for marine mammal research, it is intentionally cross-taxonomic and will also include studies on terrestrial and avian species, providing opportunities for methodological exchange and cross-system comparisons that are increasingly valuable for marine mammal science. We anticipate that BLS9 will provide a valuable forum for researchers working on marine mammal behavior, physiology, and conservation to exchange ideas, present new findings, and foster collaborations. We will share additional details (including abstract submissions and registration) as the meeting approaches. We hope this will be of interest to the marine mammal research community and look forward to welcoming many of you to Sevilla. Sincerely, Andreas [image.png]
