The Program
11-14 September 2023
First release v1.0
11 September 2023
Description: TBD
This workshop is the venue for the first formal meeting of the Antarctic Digital Magnetic Anomaly Project (ADMAP) since the COVID pandemic. We aim to gather reports on new data acquisition during and since the pandemic, discuss the challenges facing ADMAP as a result of the situation in and around Ukraine, and plot a path forwards toward the third version of the Antarctic-wide ADMAP compilation.
SCAR’s RINGS Action Group aims to facilitate regional airborne geophysical surveys in the coastal regions all around the Antarctic Ice Sheet to constrain bed topography and other key physical characteristics of the coastal regions (https://www.scar.org/science/rings/about/). This meeting will be an interactive venue to present the latest status of the RINGS Action Group including flight plans in the 2023-24 season, to strengthen ongoing collaboration with other SCAR activities, and to discuss future action items including regional airborne geophysical surveys, supplemental vessel-based and ground-based surveys, and satellite and modeling work to best utilize the data collected with the RINGS initiative.
Climate-Ice Sheet processes in Antarctica (Clip-Ant) is a subcommittee of INSTANT theme 1 that studies the interactions between the climate system and the Antarctic Ice Sheet. Our activities focus on (1) earth system-ice sheet coupled modeling at the Last Interglacial, (2) ice shelf stability, and (3) ice-ocean interaction. The first activity involves investigating the interaction between the climate system and the AIS during the LIG, using a combination of earth system and ice sheet model. Unlike PMIP, we are open to any models including some form of ice sheet-climate coupling. During this meeting, we will create protocols for experiments. The second is to produce the manuscript for the INSTANT special issue on ice shelf stability. Potential topics include ice shelf collapse, ice shelf physics and properties, and long-term evolution of ice shelves. At the meeting, we will identify contributing authors, discuss the topics, and schedule. The third aims to understand how the ocean affects the ice sheet mass balance through basal melting, with a focus on the Antarctic Slope Front and the connection between continental slopes and ice shelf cavities. Coordinated modeling studies and integrated observational studies in collaboration with SOOS, as well as planning targeted campaigns will be discussed.
The subcommittee on Antarctic and Southern Ocean (SOAS) interactions has garnered wide interest in people across disciplines (paleooceanography, paleoclimatology, climate modelling, meterology etc) and geographic regions. This workshop is the venue for the first formal meeting for the members and interested participants of this subcommittee. In this workshop, we aim to make a detailed workplan for the functioning of the group to address the research priorities, discuss ways for the subcommittee to support on-going and future research efforts relevant to the theme and discuss collaborations with other connected SCAR activities/programs.

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!
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.
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.

The objective of this ISMASS workshop is to discuss strategies and design of ice sheet model simulations that span multiple timescales in past, present and future. How can simulations of the past be used as a reliable way to reduce uncertainty for the future? How to implement paleo ice sheet simulations in order to compare them with observations and with other models?
The workshop is organised around a number of invited talks (1:30h) that will spark the discussion (1:30h). We invite participants to the INSTANT conference/workshop to actively participate in the discussion to help answer the questions listed above.
We recognise that there are ice sheet modelling approaches of different complexity, resolution and time scales of interest, as well as several possible ways to compare models and data.
This workshop encourages discussion on how these different approaches can be combined, compared and co-operated to maximise knowledge gain and reduce uncertainties.
The following topics will be addressed.
– Methods for model-data comparison: Data assimilation, ensemble of simulations, parameter calibration, Bayesian inference, emulators. Can past evolution help understanding and quantifying processes such as grounding line retreat rate and others? How does data uncertainty propagate into projections?
– Strategies for simulations: How to overcome initialisation issues? Is it possible to transfer knowledge from a “paleo” model to a high resolution model designed (and limited) to simulate a few centuries in the future? How to manage the coupling/forcing with climate models? How to design simulations to constrain relevant processes? Is it possible to define time slices during which all kinds of ice sheet models could be compared?

The Antarctic Seismic Data Library System for Cooperative Research (SDLS) was established and endorsed by SCAR in 1991 and has become the primary host of marine multi-channel seismic (MCS) data around Antarctica. This workshop is a forum for all Antarctic researcher interested in or involved with acquiring and using seismic data. We will present an update on the current status of the SDLS holdings and web page and the new SDLS guidelines. In addition, we plan brief presentations of recent and upcoming seismic field work, and discuss possible collaborations using available data. We plan also to talk about future directions, improvements, and initiatives regarding the SDLS organization and operations.
The workshop aims at discussing the status of current data/sample analyses and first results obtained from drilling the West Antarctic margin and sub-Antarctic areas during the recent International Ocean Discovery Program (IODP) expeditions 374, 379, 382 and 383. Possible correlations and linkages to glacial and oceanographic processes between the different drill target regions will be discussed and placed into a broad context with the development of the entire WAIS dynamics.

The Antarctic Geothermal Heat Flow Subcommittee is inviting all interested parties to meet and exchange ideas and updates on this topic. Whether you are an experienced researcher or new to the field, we welcome your participation, especially if you are interested in learning more about the challenges and results of geothermal heat models and measurements as well as their impact on the Antarctic ice sheet. In addition to updates on the subcommittee’s forthcoming work, there will be an opportunity for short presentations. For further details, please follow our email list by subscribing here: https://lists.scar.org/mailman/listinfo/ghf. We look forward to your participation and a productive and informative meeting.
Join us as we develop the activity of the Ice Sheet Model Intercomparison Project for CMIP7 (ISMIP7). As the climate community prepares for the next phase of CMIP, CMIP7, it is also time for the ice sheet community to discuss, develop and prioritize key research questions and protocol design for our follow-on activities. The previous effort, ISMIP6, had the key objective of improving projection of sea level from the Greenland and Antarctic ice sheets, and our understanding of the cryosphere in a changing climate. These goals mapped into both “Melting Ice and Global Consequences” and “Regional Sea-level Change” Grand Challenges relevant to CliC and the World Climate Research Program (WCRP). As uncertainties in future sea level arise due to both the climate forcing and the response of the ice sheets, a primary focus for ISMIP6 was to become better integrated in the CMIP6 initiative. ISMIP6 became an endorsed activity of CMIP6 in 2015 allowing for the first time in CMIP for ice sheets to be considered as a component of the Earth system. ISMIP6 experimental protocol explores the uncertainty in sea level projections due to ice sheet model initialization and ice sheet models, climate scenario uncertainty and uncertainty in the representation of ice-ocean interactions on centennial timescale. ISMIP6 was designed to deliver projections for use in the IPCC 6 th Assessment report. This meeting will also update, summarize and capture coordination with INSTANT community and establish a plan for next steps for ISMIP7.
The INSTANT Subcommittee 2.2 “Probing the Solid Earth and its Interactions” (PSE) aims to considerably improve the cooperation between scientists from different disciplines being active in realising in-situ geodetic and geophysical measurements in Antarctica as well as between “observers” and “modellers”. During a dedicated PSE workshop, held in Fort Collins (USA), 29 September – 1 October 2023, it was discussed how to realize and exploit geodetic-geophysical observational infrastructure in Antarctica in the future. This is especially critical when some of the current mid- and long-term GNSS and seismological infrastructure will come to its decommission phase. Following up this workshop, we are working on a white paper. On occasion of the INSTANT conference we invite all interested scientists to continue the discussion on this topic. A special focus will be given to the status of the white paper and its final publication. For further details please follow the PSE email list.
