🌏 Better models = better climate predictions.
A new paper led by ACEAS PhD researcher Claire Yung (ANU) shows how a refined equation used in ocean models can significantly improve the accuracy of Antarctic ice shelf melt predictions.

Come join us! 3 year postdoc available to work with @profmattengland.bsky.social, @mad-ros.bsky.social and myself at ANU on modelling ocean - ice shelf interactions.
Closes 4th March. If you're going to Ocean Sciences and want to chat about it, let me know!

New paper: we show that variability in the Zonal Wave-3 mode - an atmospheric pattern made up of three pairs of cyclones and anticyclones circling the Southern Hemisphere - does influence the formation and export of dense waters around Antarctica over multiple years.

Our paper on a new ice shelf basal melt parameterisation is out! tc.copernicus.org/articles/19/...
Small-scale processes in the ocean drive ice shelf basal melt, and large-scale ocean models can’t resolve these processes. Therefore, models use melt parameterisations, but these can still be improved.
I am hiring 4 postdoctoral researchers for up to 4 years each. Topics include ice sheet reconstruction, GIA, spatial stats, and satellite geodesy. Based in Tasmania.
All details are here: careers.utas.edu.au/en/listing/ with titles below
I am also recruiting multiple PhD students (see below)

For so long, fossil fuel projects have said their contribution to climate change is "negligible".
Turns out that's wrong.
Our research in NPJ Climate Action proves it.
Every tonne of CO2 matters.

We figured out a cheap-ish way to make ocean models create Dense Shelf Waters (DSW) on the surface of the Antarctic continental shelf! How?
Fast answer: Ocean surface cells thinner than 1 m!

🚨 New paper alert 🚨
We developed the new PanAntarctic model and assessed the sensitivity of Antarctic Bottom Water (AABW) formation and export to horizontal model resolutions of 1/10°, 1/20° and 1/40°.

The 2026 budget passback plan calls for eliminating NOAA Research, the scientific backbone that keeps weather forecasts, alerts, and warnings accurate and effective. This would have disastrous consequences.
Read the AMS statement, in partnership w/ @nwas.org: bit.ly/4cz2RtC
It's even worse than removing the grant funding for university research (in groups like mine at UC Irvine). NOAA labs and cooperative institutes collect the climate data we use, develop the predictive weather and climate models, and train the students we hire.
This demolishes U.S. climate research.

Cuts to #science of >50% at NASA and >75% at NOAA would end US climate and space science research.
