Advancing European Research Priorities in Antarctica and the Southern Ocean (EBP/Euro-Polar Net2)- 15:30 to 17:30
– Room A
Organiser: Kirsi Latola & Anna-Maria Perttu

Description: EU-PolarNet is a project funded by the European Commission H2020 CSA action with aim to strengthen connections between the polar scientific community and stakeholders to define research needs. The European Polar Research Program (EPRP, 2020) was developed within EU-PolarNet as a bottom-up community process of co-designing and co-developing a future research agenda for Europe (https://eu-polarnet.eu/wp-content/uploads/2020/11/EPRP_final_version-1.pdf ). EU-PolarNet is now prioritizing and updating the research program. Aim of this session is to feed into that process and discuss the pressing research needs in relation to environmental protection of Antarctica and the Southern Ocean. For Europe, understanding how particularly Antarctic ice sheets affect sea-level rise is a question of great urgency. The SCAR INSTANT program on how the ocean, atmosphere and cryosphere have influenced ice sheets in the past, and the future expectations with a special focus on quantifying the contributions to global sea level change. This conference thus provides a unique opportunity to gather stakeholder input important to the EU-PolarNet 2 prioritisation. The updated research priorities will be widely communicated to relevant European and global polar stakeholders, including polar organisations, institutes, research funders, organisations like EPB, SCAR, IASC (and ICARP IV process), and other relevant organisations and processes including IPY 2032-33.

Southern Ocean-Antarctic Chronology and Environmental proxies (SOACEP) – 15:30 to 17:30 – Room B
Organiser: Laura De Santis & Dave Chandler

Description: The SOACEP subcommittee contributes to the aims of INSTANT by i) reconstructing environmental variability throughout the geological past to constrain glacial processes and ii) standardising age models to improve the correlation of events and constrain rates of change. Alongside ongoing work for the subcommittee, we are producing two white papers for the end of 2023. 1) Southern Ocean – Antarctica environmental proxies: scope of existing datasets and priorities for future reconstructions. Proxies needed by the community, what data are available, where are they located, what are trusted proxies and which proxies or regions should be prioritized for future work. 2) Chronology and correlation of Antarctic glacial change. A catalog of terrestrial and marine chronological methodologies, to identify key barriers in dating glacial change in Antarctica and summarize what is needed in this space to advance Antarctic research, with a focus on standardization of developing age models and reporting uncertainties. In this workshop we will: • Discuss progress in subcommittee activities • Review and update the subcommittee work plan • Discuss the white paper progress coordinating with others This workshop hopes to engage current and new members to contribute to the work plan. All welcome!

ICE-Ocean- Lithosphere Interplay in East Antarctica (ICEOLIA) – 17:00 to 18:30 – Room C
Organiser: Laura De Santis & Guilhem Barruol

Description: The marine ice sheet covering the Wilkes Subglacial Basin (4-6 m sl equivalent) is forecasted to significantly retreat by 2500 if no climate mitigation actions are taken. Much shorter and sudden effects may happen during the present century given the large uncertainties in current models’ projections. There is therefore an urgent need to harvest observational data from this East Antarctic Ice Sheet sector to understand the mechanisms, forcings and feedbacks driving the ice sheet instability and to constrain models estimating global sea level rise for policy makers, in time to apply mitigation and adaptation actions. The ICEOLIA (ICE-Ocean- Lithosphere Interplay in East Antarctica) initiative ambitions to employ multiplatform surveys involving remote sensing, geophysical and glaciological observations on land, as well as oceanographic, geophysical, bathymetric and sediment sampling marine surveys, for short term measurements and long term monitoring. Such an integrated and multidisciplinary approach will be carried out by a pull of European institutions, led by France, Italy and UK in synergy. Targeting ambitious science in this region absolutely requires an international cooperation and coordinated task force involving also extra EU institutions ready to work hand in hand and with multiple platforms, for more than a decade. The ICEOLIA workshop welcomes people with interest and ongoing projects in the area of the Wilkes and George V Land interior and continental margin, to plan coordinated and cooperative actions. The ICEOLIA workshop is an initiative of the EA-MISI (East Antarctic-Marine Ice Sheet Instability) service that receives funding from EU-PolarNet 2 via the European Union’s Horizon 2020 research and innovation programme under grant agreement No 101003766. It is co-organized with the Risk of East Antarctic Collapse & Tipping-points (REACT) Initiative led by the Australian Antarctic Program.

High-Resolution Seasonal to Decadal Records (High res) / CLIVASH 2k – 13:30 to 18:30 –
Organiser: Quentin Dalaiden & Dieter Tetzner/

Description: The INSTANT sub-committee on proxies and processes will be hosting a workshop on the afternoon of 12th of September. The purpose of this workshop will be to gather the community interested in this INSTANT sub-committee, collect ideas and discuss the main points that need to be addressed over the next three years to: 1) Improve our understanding of atmosphere-ocean-ice interactions over seasonal to centennial timescales. 2) Establish the role of sea ice on Antarctic SMB over seasonal to centennial timescales. 3) Quantify the role of winds and atmospheric circulation on SMB variability. This workshop will be the kick-starter for our INSTANT sub-committee. The outcomes from this workshop will drive the agendas for further sub-committee work. We will welcome scientists from all career stages and backgrounds and particularly encourage early career researchers to participate.
