Hi all,

Our next CMWG meeting will be held next Wednesday 6th Aug from 10:30-11:15 am Melbourne/Canberra/Hobart time (AEST). We only have a seminar on the agenda:

  • Seminar by Asst. Prof. Ching-Yao Lai (Stanford University) 10:30-11:15 am

Title: Deep learning the flow law of Antarctic ice shelves

Abstract:

Can AI help uncover unknown physical laws from vast amounts of Earth data? In this talk I will discuss data-driven exploration of the constitutive law (i.e. flow law) of ice shelves using physics-informed deep learning and remote-sensing observations (Wang, Lai, Prior, Cowen-Breen, Science (2025)). The constitutive law of ice directly governs the dynamics of land ice but is challenging to measure in the field. Here, with physics-informed deep learning and remote-sensing observations, we identify constitutive models that differ from those previously assumed in ice-sheet models. Our results suggest the need to reassess the impact of ice flow laws on the future projection of sea-level rise.

Bio: Yao is an Assistant Professor in the Department of Geophysics and the Institute for Computational and Mathematical Engineering at Stanford. Before Stanford, she was an Assistant Professor at Princeton University. She did her undergraduate degree (2013) in Physics from National Taiwan University, a PhD (2018) in Mechanical and Aerospace Engineering from Princeton University, and postdoctoral research at Columbia University where she received the Lamont Postdoctoral Fellowship. Her current research focuses on integrating mathematical models and machine-learned models to tackle problems in the cryosphere. She was the recipient of the 2023 Google Research Scholar Award and the 2024 Sloan Research Fellowship.

Title: Antarctic landfast sea ice: Understanding worrying trends, and progress in model representation and remote sensing.

Brief overview: In this talk I will cover the progress made toward delivering the main aspects of my Future Fellowship: Automated mapping of fast ice, new knowledge of fast ice thickness and roughness, drivers of fast ice, and incorporation of realistic fast ice into the CICE model. None of the science would have been possible without a fantastic bunch of ECRs including Honours student Gabby Burke - fast ice automated mapping, Masters student Claudia Stepin - fast ice thickness and roughness remote sensing, Masters student Kaihong Jiao - grounded iceberg automated mapping, PhD students Dan Atwater, fast ice modelling in CICE; and Andrew Einhorn, fast ice drivers investigation, and postdocs Pat Wongpan - grounded iceberg mapping; and Johannes Lohse, fast ice automated mapping. I will do my best to synthesise all their great work within the time limit!

Hello,

ACCESS-NRI is going to have significantly more compute resources on Gadi for the first half of 2026. As a consequence, all working group projects will receive an allocation of 1.5 MSU per quarter for that period. We will still look at re-allocations during the quarter to optimise usage.

Please use the resources as you need them.

:police_car_light: NCI PROJECT nf33 ACCESS

As 2025 draws to an end, ACCESS-NRI are doing some festive season tidying of NCI project memberships!

We intend to remove members from the NCI Project nf33, the ACCESS-NRI Training project used during the ACCESS-NRI workshop back in September.

Access will be removed on Friday December 19, 2025. As a result, members will no longer be able to access compute resources, or access data associated with this project.

If you are still actively using this project, please contact @lawrenceabird before the end of this week to prevent losing access.

This year, we are introducing multiple opportunities for community input as the work plan is developed and refined. Feedback will be sought at three key stages, allowing ideas and priorities to be shared early, and reviewed as the plan takes shape.

Key dates for community input and feedback

  • 5 February – 16 March
    Online form opens to collect early input and feedback to inform drafting of the new work plan.
  • April
    Community feedback on the initial draft of the work plan.
  • Mid-late May
    Final community review (for minor updates only).

The online form for early input is now open and closes on 16 March, 2026. To help inform your feedback, you may wish to refer to our current-year status report (FY2025-26).

We encourage community members to share their ideas, priorities and suggestions via this form. Early feedback will help inform the initial drafting of the work plan.

We look forward to working with the community to shape priorities for the coming year.
