Mesoscale and submesoscale structures — such as cyclonic and anticyclonic eddies, filaments, and fronts — play a fundamental role in shaping marine ecosystems. These dynamic features have been demonstrated to impact the distribution of nutrients and enhance biological activity across trophic levels. They influence key processes including phytoplankton blooms, larval dispersal, and the biological carbon pump. Despite the growing recognition of their importance, the complexity and scale of these interactions are still not well understood, limiting our ability to quantify their regional and global impacts. Technological advancements, such as higher-resolution ocean models and new generations of satellites like PACE and SWOT, are creating unprecedented opportunities to study these fine-scale processes, while also posing new challenges for data interpretation and integration. This session invites contributions investigating the interplay between physical processes and biological responses at meso- and submesoscales. We aim to bring together observationalists, modelers, and theorists working at the interface of physics and biology to deepen our understanding of how ocean dynamics at these scales influence marine life.
