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.

Stratified suppression of turbulence in an ice shelf basal melt parameterisation
Abstract. Ocean-driven basal melting of Antarctic ice shelves is an important process that affects the Antarctic Ice Sheet, global climate and sea level. Basal melting is controlled by small-scale pro...

ANU colleagues and students - please share this post if you can: The ANU governance project has extended our deadline to comment on the Draft report to next week - 7 October. Here's a link to a feedback form, which also contains the link to the draft report: docs.google.com/forms/d/e/1F...

Feedback on ANU Governance Project Draft Report
The ANU Governance Project Working Group are proud to present the Draft Project Report for community feedback and consultation. The Draft Project Report is available on our website or through THIS LINK. Using a process that has involved deep listening and a participatory and deliberative process across the ANU community, we have compiled a unique and valuable body of evidence that documents what’s wrong with governance at the ANU and charts a way forward to help rebuild trust and to deliver best practice governance. Over 600 ANU staff, students, and stakeholders have participated in this project, and in contributing constructively to the future of ANU. This includes 590 members of the community who participated in our survey, 75 who participated in one-hour small group discussions, and over 40 from across the university who participated in our project workshop. The ANU community told us there a critical need for change: Over 96% of survey respondents and all discussion group participants believe current ANU governance is not fit for purpose and should be reformed. Over 92% of survey respondents and all discussion group participants expressed dissatisfaction with current ANU governance. Over 93% of survey respondents said they were dissatisfied with current practices of transparency at the ANU. Over 93% of survey respondents said they were dissatisfied with accountability frameworks at the ANU. The ANU Community has proposed the following near-term steps forward for a reformed ANU: Council must direct Finance to produce and publish a current budget breakdown. Council must revise and publish selection criteria for Executive positions. Council meetings must immediately be made fully accessible to the community. Academic Board must regularly review and assess the financial decisions of senior executives and Council. Commence senior leadership listening tours with the ANU community. Additional recommendations forwarded by the community are summarised in the full report, including a proposal to co-design legislative reform of the ANU Act with the community. The Working Group invites the ANU community and stakeholders to offer feedback via this form on the draft report by midnight on Tuesday 7 October. This deadline has been extended in order to allow us more time to hear and incorporate community feedback ahead of the release of our final report on Monday 20 October.

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! Long answer on the paper: dx.doi.org/10.1029/2024... ---- More info in the thread

This is horrible. I don't even know what to say. Some of our most key polar data. "As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported." nsidc.org/data/user-re...
Effective May 5, 2025, NOAA’s National Centers for Environmental Information (NCEI) will decommission its snow and ice data products from the Coasts, Oceans, and Geophysics Science Division (COGS). As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported. This includes Sea Ice Index, Snow Data Assimilation System (SNODAS) Data Products, Glacier Photograph Collection, U.S. National Ice Center Arctic Sea Ice Charts and Climatologies in Gridded Format Gridded Monthly Sea Ice Extent and Concentration, 1850 Onward World Glacier Inventory. If you rely on these products in your work, research, education, or planning, we invite you to share your story at nsidc@nsidc.org. Your input can help us demonstrate the importance of these data sets and advocate for future support.

One of the people fired from NOAA today is the director of the Ocean Acidification Program. That program also leads the U.S. government's effort on marine carbon dioxide removal (mCDR). The destruction of American science is incomprehensible.

🤓 in just 6 years, australia's two main grids added 51 TWh/yr of wind+solar generation. …taking us from 19.9% → 38.8% renewables. …this is equivalent to 6.6 large #nuclear reactors, but at much lower cost & much faster. …even more impressive given there's no chance of nuclear here for 20+ years.

Sea ice is very different to fresh ice, and incredibly difficult to represent accurately in climate models. With the new sea ice facility in the CFP Lab, we can grow sea ice in controlled conditions and unlock its mysteries.
