OralS2: MOSAiC and Beyond: Cross-Cutting Results and Future Plans for Icebreaker-Based Arctic Research

[S2-O]S2:MOSAiC and Beyond: Cross-Cutting Results and Future Plans for Icebreaker-Based Arctic Research

Wed. Oct 29, 2025 11:15 AM - 12:45 PM JST
Wed. Oct 29, 2025 2:15 AM - 3:45 AM UTC
Main Room (Room C/D)
Chair: Yusuke Kawaguchi (Kitami Institute of Technology: KIT)
This session invites contributions presenting recent findings and upcoming plans from Arctic field campaigns supported by icebreakers, focusing on interdisciplinary work encompassing meteorology, oceanography, biogeochemistry, and environmental technology. A key emphasis is the MOSAiC expedition aboard Polarstern (2019-2020), which produced unprecedented datasets revealing intricate atmosphere-ice-ocean interactions. We also welcome results from other Polarstern cruises (e.g., ArcWatch) and studies around Svalbard, marginal ice zones, and fjords, where localized processes reflect broader environmental change. Presentations featuring innovative methods, emerging sensor technologies, autonomous platforms, and integrated modeling approaches are especially encouraged. By bringing together researchers involved in current and planned Arctic campaigns, this session aims to deepen scientific understanding, foster collaboration, and help shape the future of Arctic research.
