Please join us for a Mathematical Modelling of Fluid Mechanics seminar on Monday 15th May at 4.30pm (Sydney/Melbourne time).
We are delighted to have Dr Katarzyna Kowal (University of Glasgow) giving a talk on Thin-film flows: why substrates matter. Abstract below. Zoom link.
If you haven’t already, you can join the seminar series mailing list here. And please forward this email to any of your students or colleagues who would be interested.
Best wishes,

Thin-film flows: why substrates matter
Dr Katarzyna Kowal (University of Glasgow)
Thin-film flows are ubiquitous in nature and industry, with a range of geophysical, environmental and industrial applications. Many of these exhibit vastly different dynamics when spreading over different substrates. Examples include the dynamics of large-scale ice sheets, which flow orders of magnitude faster when lubricated from below, and a range of flows over hydrophobic surfaces, which promote drag reduction. In this talk, we will examine the role of the substrate, specifically how well it is lubricated and how it deforms, on the flow of an overlying thin film of viscous fluid, and relate our findings to the flow of ice sheets and the geophysical features that form as a result. A particularly intriguing feature involves the formation of so-called grounding zone wedges, or accumulations of soft, subglacial till in ice-sheet grounding zones, separating ice sheets that are grounded over bedrock from freely floating ice shelves.

On Thursday 7th September, we will be hosting a Cryosphere Working Group meeting after the main ACCESS-NRI meeting in Canberra.
This will be an opportunity to delve more deeply into cryosphere science that is being undertaken by the community, to discuss key questions in the field, to hear the latest about coupling ice sheet models into ACCESS-NRI, and for training.
To facilitate with planning, we’d love to hear your thoughts on whether you’ll be attending and what you’d like to see happen in this form: https://forms.gle/6sJ5buEsW8ddDjt49
There’s also a link in that form to a spreadsheet where we’re collating details about different ice sheet model capabilities. Please take a look and fill out if you’re a current/past user of an ice sheet model. Access here: Ice sheet model capabilities - Google Sheets
Looking forward to seeing you in September!
Warmly,
Felicity & Ben

MEETING REMINDER AND AGENDA
WHEN: 12 July, 10:30-11:30 (recurring every 6 weeks) (If you would like to subscribe to the WG calendar, see below)
Due to some technical difficulties last week, this meeting did not go ahead. Our next WG meeting will be held Wednesday 23 August from 10:30-11:30.
It’d be much appreciated if you could fill out the below form with your intentions for the ACCESS-NRI workshop on 7th September, as well as info on any ice sheet model you may have experience with:
Registration for the upcoming ACCESS-NRI Cryosphere modelling Working Group meeting is now open. The workshop will be held on Thursday 7 September from 9 am - 4:30 pm (with a networking opportunity from 8:30 am) at the ANU in Canberra, with an online option.
We will be asking all attendees to present something for a science discussion at the workshop, and we will provide you with more details at the next Cryosphere WG meeting on the 23rd August and via email that week. Please monitor the Cryosphere WG Hive Forum announcements for more details.
Firstly, if you’ve not already registered for the Cryosphere WG meeting on the 7th September, as part of the ACCESS workshop, please do so using this form: https://forms.gle/y5R5AvWqVYCJuk6Y6
A reminder that we have our next WG meeting this Wednesday 23rd August. Details below.
WHEN: 23 August, 10:30-11:30 (recurring every 6 weeks) (If you would like to subscribe to the WG calendar, see below)
A reminder we have a Crysophere Modelling WG workshop on 7 September from 9 am - 3 pm. The agenda is attached. The zoom link for the meeting is: Launch Meeting - Zoom
Meeting ID: 889 8141 7260 and passcode: 870161 ACCESS_cryo_workshop - Sheet1.pdf (46.1 KB)
For those of us meeting in person at the Cryo Modelling WG workshop tomorrow, we’ll be in Level 1 – Lennox Room, in the same building as the ACCESS-NRI workshop.
Please find links below for documents to complete during sessions 1 & 3.
We are intending to hold a 1-day in-person workshop in late October/early November to finalise the terms of reference and process for advising on an ice sheet model to include in ACCESS-NRI. Please indicate your availability in the form below.
Thanks to everyone who has responded on the google form above. If you’ve not yet done that please do so asap so we can lock in a date.
Also, @Chen_Zhao and I put together some thoughts on an ice sheet/glacier modelling toolbox/cookbook, including some notes on datasets that we’d like to make commonly available to all (hopefully on gadi). Take a look at this doc and add your suggestions: Ice sheet model cookbook, toolbox & data - Google Docs
BUT WAIT!! Don’t just add you suggestions - also add where you can contribute! We are developing a plan to make the process of getting started up with a toolbox/cookbook a bit more seamless and straightforward too, so watch this space…
A reminder that the next Cryosphere Working Group meeting is coming up on Wednesday (4-Oct 1030-1130 AEDT). If you’d like to add the WG meeting series to your calendar, download/add this link to your calendar: link
