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.
If you have something new to share â modelling, observations, theory development, cool new tools or data products â related to the cryosphere, weâd love to hear from you!
Talks and a poster session will be scheduled for the morning â 8:30-11 â followed by a CMWG general meeting, lunch, then an ISSM / pyISSM tutorial.
Please get in touch via email with Mike, Lenneke, Chen, or myself if you would like to present or want to find out more.
Looking forward to seeing you there!
Cheerio,
Felicity

Dear CMWG,
A quick note to let you all know that application window for the below position has been extended by 1 week - so applications now close on Tuesday 26 August, 11:55 AEST.
Please spread the word and get in contact with either Felicity McCormack or myself for more information.
Have a great weekend!
We have recently opened a job advert for a 3-year Research Fellow position based at Monash University in Melbourne, Australia. The role is to couple the Ice-sheet and Sea-level System Model (ISSM) with the ACCESS-AM3 atmosphere model.
09:10 - 09:40 - COSIMA Working Group plenary presentation (suggested / optional): Claire Yung (ANU) - Progress and challenges in modelling melt and ocean circulation within ice shelf cavities. Rm: Forum 1.
â
09:50 - 10:30 - CMWG general meeting and discussion. Rm: M03
15:15 - 15:30 - Any other business, wrap-up and thank you. Rm: M03
Please note: We have been assured by the event organiser that room M03 will have zoom capabilities for remote attendees to join the CWG meeting. However, we will not have the zoom details until next week, so I will share these as soon as we have them!
Also, for those attending the âIntroduction to ISSM / pyISSMâ sessions, we will post the course guide / pre-requisite instructions on the forum tomorrow.
Any questions please donât hesitate to reach out to me (@mtetley) or Lawrence (@lawrenceabird).
This information is for all those intending to attend the Introduction to ISSM/pyISSM Workshop as part of the Cryosphere Working Group meeting at the ACCESS-NRI Workshop 2025 on September 12, 2025.
Workshop Resources
All resources for the workshop are now available in this repository. We have included detailed instructions for getting started here.
Pre-workshop preparation
To get the most from the workshop, there are a few steps to complete ahead of time:
NCI Account - This workshop has been designed to operate on the Australian Research Environment (ARE), a web-based graphical interface for performing computational research on the National Computational Infrastructure (NCI) Gadi supercomputer. In order to access ARE, you will require an NCI account. If you do not have an NCI account, you can sign up here.
NCI Project Membership - To run the exercises you will require access to two specific projects on Gadi:
xp65 - ACCESS Analysis Environments - This project hosts the shared analysis3 conda environment that contains all the Python packages used throughout the workshop.
Please request to join these projects at least 1-2 days before the workshop to allow for your request to be approved.
Getting started
If youâd like to get started ahead of the workshop, we invite you to work through the instructions here, starting at Step 0.
During the workshop, we will walk through Step 1 and Step 2. You will then be able to work through the tutorials at your own pace, with ACCESS-NRI staff on-hand to answer any questions or help troubleshoot any issues.
See you there
Weâre excited to see you all there on September 12, 2025. The ISSM/pyISSM introduction hands-on session will begin at 11:30 in Room M03.
A reminder that we have our CMWG general meeting and discussion at 09:50 in Room M03 and hope to see you at the COSIMA Working Group plenary presentation at 09:00 in Forum 1. The full schedule for the day is here.
Virtual attendance
We have been assured by the venue (Melbourne Connect) that the room booked for the Cryosphere Working Group meeting and the above Introduction to ISSM/pyISSM session will have zoom access for remote attendees for the full program.
We will provide the zoom meeting details as soon as we have them early next week here on the forum.
Help me!
If you have any questions before the workshop, please reach out to @mtetley or @lawrenceabird. Look forward to seeing you all next week!
If you are unable to join us in-person on Friday (September 12) for the Cryosphere Working Group meeting and the Introduction to ISSM/pyISSM session, you can join the session online using the Zoom details below. The Zoom meeting will be active from 09:30 following the COSIMA Working Group plenary presentation.
Weâre excited to see you all there (both in-person, and online)!

Hello all,
Exciting news!
Please find below the details for the recently advertised ISSM-OM3 (ice-ocean) coupling position based at UTAS in Hobart and working closely with the ACCESS-NRI Ice Sheet Modelling team.
Questions? Would like more information? Please donât hesitate to reach out to either @Chen_Zhao or myself (@mtetley) and please feel free to share with any interested colleagues.
We are pleased to announce that the Institute for Marine and Antarctic Studies, University of Tasmania is recruiting a Coupled Ice SheetâOcean Modeller (Level A or Level B) based at Hobart, Australia.
This position will play a central role in advancing coupled modelling of the Antarctic Ice Sheet and the Southern Ocean.
In this exciting role, the successful candidate will:
ACCESS-NRI is developing a âCryosphere Data Poolâ â an efficient and centralised data discovery and access tool hosted on NCI Gadi . The Cryosphere Data Pool will allow users to access common datasets used within Cryospheric Sciences and ice sheet modelling, as well as other datasets generated by the ACCESS community.
We need your help
We are seeking community input to populate a list of key datasets to be included in the Cryosphere Data Pool. Please visit the Hive Forum for more information on how to contribute:
We are seeking input by October 18, 2025.
If you have any questions, please reach out to @lawrenceabird.
