Interesting thought @germac.bsky.social, I have often thought I could identify signatures of the Med in various diagrams but never go answering this exact question. Conveniently the med contribution is pretty easy to identify by its salinity. I have thoughts on how to do it (in a gcm at least)

Paper just out in AI4Earth led by the incredible @eveapiedagnel.bsky.social. We show how to exploit the ocean’s tight T-S relationship at constant pressure to map trends in salinity from sparse data doi.org/10.1175/AIES.... GMM works well because the relationships are so linear, but why are they?

If anyone is at BACO25 looking for the room where a certain someone might be talking this morning πŸ‘€β€¦it’s M211 - go right at the top of the escalator as you reach level 2. πŸ™‚

Very proud of our student Josef (Joey) Bisits. My first time in JFM. It turns out you can have a stratified water column, mix it a little, and it becomes unstable. Fluid dynamics is fun!!!

I was going over a digital version of a paper from the 80s with my student yesterday and the scan was so bad we could distinguish some of the labels in a figure. I said he should ask the author (Trevor McDougall) for a preprint as I know he has kept them, at least until recently.

Seems everyone has arrived at BlueSky! I am taking some holidays till January but looking forward to communicating with you all more on the platform about climate/ocean/fluids/data in the NY! πŸ₯³πŸ˜ŽπŸŽ„

As far as I know this isn’t an early April fools joke. I’m excited to try to get back to Scotland - though less excited to be there in February

Just submitted an ARC DP EoI. 2 improvements in addition to 2 stages imho: 1. CV section is shorter (in one bit 5pages is swapped with 1500chars!) 2. Project partners only need to prepare a 1 page CV. I am now no longer embarrassed to ask international partners to do the paperwork for a full β€˜ROPE’.

What is your niceness limit? I just got requests from a PhD program to give a reference for a student who took a graduate class of mine 2 years ago. No warning from them. I only have their old student email which bounces. I’d like to think I’m a nice guy but…

Anthropogenic Aerosols Offsetting Ocean Warming Less Efficiently Since the 1980s Since 1980, aerosol-driven ocean cooling has decelerated substantially, alongside a drop in ocean heat uptake efficiency The drop in ocean heat uptake efficiency is limited to the tropics, which ...

Really proud of this work, which went from an idea back in August 2022, to a published piece this week! With co-authors Damien Irving, @janzika.bsky.social, and Jonathan Gregory, we explored the reduced impact of aerosols on our climate system:
