Some eye-opening work out by my erstwhile colleague Amy Macfarlane today in Elementa, looking at the environmental impact of the MOSAiC expedition. online.ucpress.edu/elementa/art...

Something that I did not hear discussed at the time (and have not heard since) is the symbolism of the Russians sending their icebreaker RV Akademik Federov to assist RV Polarstern at the start of the 2019/20 MOSAiC sea ice drift campaign. They had newer & more powerful ships, so why pick Federov?

Up close and personal with one of the Arctic's infamous boundary layer inversions!

Updating a figure with 2025 data for a research proposal. The shift in conditions around 2016 are becoming starker by the year...

As my PhD came to a close in 2022 I was lucky to join an icebreaker campaign in the Weddell Sea. TLDR: lots of very hard, very coarse snow. Rosie Willatt then led a very nice analysis of the radar data we collected, and it's out today in GRL. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Paper out today led by @aliduffey.bsky.social where we compare the atmospheric boundary layer in climate models to 7000 vertical profiles from Soviet ice stations + ~500 from the MOSAiC & SHEBA campaigns. More forays into the world of polar meteorology to come! dx.doi.org/10.1029/2024...

Representation of Arctic Winter Atmospheric Boundary Layer Stability Over Sea Ice in CMIP6 Models

A cloudy state, without strong low-level stability (LLS), is often observed over winter Arctic sea ice but is absent in most Coupled Model Intercomparison Project (CMIP6) models CMIP6 models show...

Fun to speak to the Blue Compass conference in Tromsø today about Arctic sea ice decline: it's strongly confined to shallow waters and exclusive economic zones, posing an immediate governance challenge.

Some new work out today on salt movement in snow covered sea ice, led by Anton Komarov at U Manitoba. Anton ran with the lab approach I used with Vishnu Nandan, but eliminated some of methodological uncertainties to produce much more compelling results. www.cambridge.org/core/journal...

already in an early career catastrophe research role but thanks

Kelly Hereid@kellyhereid.bsky.social · last yr.

Hi all, we're hiring an early career catastrophe research role in our group! Master's or PhD, flexible on area of specialization, experience in cat modeling not required. US only but remote is available, we've got a hybrid team in Boston, London, and scattered across US and UK.

Really happy to be one of two finalists for "Best popular article written by a scientist" this year at the ABSW awards. Particularly poignant to be considered for the Katharine Giles Award. I never met Katharine, but I was often steered by her legacy while working for @cpom-uk.bsky.social

Giving a lecture this afternoon about sea ice formation processes - since it is "Pancake Day" in the 🇬🇧 this slide took on a whole different relevance Image of super strong ice pancakes in the Weddell Sea in 1992

Short critique of my own work out today in J Glaciology. Five years ago I made a back-of-envelope calculation of seasonal densification rate of snow on sea ice. It unexpectedly became quite popular! Here I show it was roughly right even if the method was a bit dodgy... doi.org/10.1017/jog....

Can climate models reproduce observed trends? The answer can be challenging. Our new review paper in Science Advances led by Isla Simpson and Tiffany Shaw @drshaw.bsky.social discusses challenges and ways forward in confronting climate models and observations. www.science.org/doi/10.1126/...

Inspired by @zacklabe.com to put my invited talk slides online. www.robbiemallett.com/presentations One thing you'll notice is that I'm fond of the animated GIF! A thread of my favourites, starting with not-graphs. [Divers surfacing from under Antarctic sea ice at Rothera]

Very sceptical that an ice floe could be 3m wide and 10m thick. Not least because it would float in a way that would make it 10m wide and 3m thick....

This #PancakeDay here's our recipe for pancake ice: 🧊 Get some ice forming on the top of your water 🌊 Bump bits of ice together with small waves ♻️ This rounds their edges as they freeze! 🥞 Grow the disc edges with trapped frozen foam These pancakes will be up to 3m wide + 10m thick. Bon Appétit 👩‍🍳

Exciting to see U Waterloo's CryoSAR on the Calgary airport runway last night. Side-looking Ku- and L-band radars mounted in a Cesna caravan. Sadly no passenger seats for today's flight over Fortress Mountain 😭

A real and sad loss for American climate science. Zack has inspired me since the beginning of my polar science journey. If I turn out to be half the scientist he is, I'll be happy. This move is disrespectful to him, but also to the public.

Last Tuesday, I was set to give a talk on 'climate change in the Northeast' at a retirement home but had to cancel due to hourly job threats. After nearly two weeks of overwhelming uncertainty, today it happened. I was fired from my dream of working at NOAA. I'm so sorry to everyone also affected.

We successfully simulated a sea ice flooding event inside the Churchill Marine Observatory today! We sawed out our snow covered slab from the ice sheet and achieved a negative freeboard, taking a suite of geophysical & isotopic observations before and afterwards.

Excited to start my SCAR Fellowship adventure!

🇦🇶 Meet the 2024 SCAR Fellows 🇦🇶 We're thrilled to award five SCAR Fellowships this year, supporting ECRs in Antarctic science. 🌍❄️ We'd like to thank the Prince II Albert Foundation & KOPRI for their support! Applications for the 2025 Fellows will open later this year. 👏 scar.org/scar-news/20...

This week in "ideas I thought were new but actually aren't". In the final sentence of her 2005 PhD thesis, Katherine Giles stressed that it would be really neat to steer ICESat onto a CryoSat ground track. It took 15 years and a second iteration of both missions for Cryo2Ice to happen!

January 2025 was quite unexpectedly the warmest January on record at 1.75C above preindustrial, beating the prior record set in 2024. This is despite the presence of La Niña conditions in the tropical Pacific, with the El Niño event of 2023/2024 long faded. www.theclimatebrink....

Good day to be a snow scientist

IASC Newsletter now out! Congratulations to friend & colleague @aliduffey.bsky.social, who will be this year's Atmosphere fellow. Also well done to incoming Cryosphere Fellows Ellie Miller and Leena Leppänen - I look forward to passing the baton in Boulder! iasc.info/news/iasc-ne...

Good day snowshoeing today
