  • Sea ice dynamics structure narwhal presence and seasonal movements in a Northwest Greenland fjord system. Larsen, Julie Sofie K Ladegaard, Michael Madsen, Peter T Olsen, Steffen M Simon, Malene The Arctic is experiencing unprecedented environmental change, with diminishing sea ice reshaping marine ecosystems. The narwhal (Monodon monoceros) exhibits strong site fidelity during seasonal movements and continued sea-ice decline has the potential to alter important habitats. This study aimed to understand narwhal presence at different sea-ice stages by combining long-term passive acoustic monitoring (PAM) with satellite-derived sea ice data from Inglefield Bredning, Northwest Greenland (June 2022-September 2025). Generalized linear mixed models (GLMMs) revealed a highly significant effect of sea-ice stage on narwhal acoustic activity (p
