🌨️ Clouds over the cold Southern Ocean are different from elsewhere in the world. Here they are seeded not by aerosols from land, but by the ocean — and even life itself.
Chelsea Bekemeier, from @ColoradoStateU on the Denman Marine Voyage #DMV, explains.

Join our atmospheric chemistry modeling team in Grenoble to work with @HeleneAngot on modeling atmospheric microplastics. Apply at emploi-univ--grenoble--alpes…
A commentary paper I worked on with a bunch of great collaborators was published recently. We discuss how Southern Ocean clouds are influenced by biology and summarise some of the huge efforts to learn more.🔗: bit.ly/456hwsn and a nice writeup by @Ant_Partnership below
☁️ What makes clouds in the Southern Ocean around Antarctica different from elsewhere in the world?
In this relatively pristine region without dust or pollution, clouds are seeded by tiny airborne particles (aerosols) that come from the ocean itself.

🚨 Excited to share new work! 💻🌞🌏🌊 We used machine learning with #ERA5 to more accurately simulate sunlight over the Southern Ocean. I learned a lot during this project and can't wait to see what's next.🔗: bit.ly/3MgTi7f #ClimateScience #machinelearning @AMS_AIES
😎 Our AAPP researchers from partners @AusAntarctic, @BOM_au & @IMASUTAS use #MachineLearning to simulate solar radiation in the Southern Ocean - crucial to improve weather and #climate modelling.

📣 Come work for us! We are looking for a Research Associate to undertake research on quantifying the marine biogeochemical cycling of carbon and the progress of acidification in the Southern Ocean using a suite of existing observations 🌊

Remember when the 2019-20 AUS bushfires fertilised the South Pacific? There's more to the story! See our new study in #AGUPubs Geophysical Research Letters: agupubs.onlinelibrary.wiley.…

Next week the @CATCH_science Open Science Workshop is on! @MarcMallet, @ruhihumphries and myself have organised a session designed to start early discussions on upcoming Southern Ocean voyages targeting biogeochemistry links to aerosol and clouds! indico.psi.ch/event/12700/se… /1

On Thursday 28th April @HobartBrewing, come and hear Dr @CayneLayton, Tasmanian STEM Researcher of 2021 and Neptune's head gardener, talk about efforts to restore Tasmania's giant kelp forests. #MarineScience #scicomm @IMASUTAS #kelpforest #hobart

The Annual @CASANZ2 aerosol assembly is underway! The first session is all about aerosol transmission of #COVID19 - with #Times top 100 most influential people Lidia Morawska up first! @QUT My take away message: the key to transmission is inhalation! #ventilate #COVIDisAirborne

This two-day workshop is open to all of our partners. Presenters will explore topics in machine learning from clustering to artificial neural networks, and everything in between. Follow the link for info and registration.

I turned a personal project into a paper that I'm quite proud of. I showed that changing weather is (mostly) not responsible for worsening air quality in an Australian mining town: authors.elsevier.com/a/1cZnz…
... and if anyone is interested in dabbling in some machine learning and how it can be used to isolate the effects of weather on air quality, check out the R package, rmweather, that sparked my interest: github.com/skgrange/rmweathe…
It's always a pleasure heading out to Cape Grim. I was the first visitor to the station since March and helped calibrate a new @CSIRO aerosol mass spectrometer there for long-term measurements.

The @AMOSupdates online conference #AMOS2021 call for abstracts is now out! If you have some exciting science to share, especially if it involves clouds and aerosol over the Southern Ocean (S9.2), consider making a submission! amos.eventsair.com/amos-2021…

Will the Southern Ocean clouds act more as a warming blanket, or as a cooling sun shade? It's one of the most important questions for climate modellers today, and research by the AAPP's @MarcMallet is helping find the answer.

Don’t forgot to put your @AMOSupdates session proposals in today! @MarcMallet @flang24 and I put one in for #SouthernOcean atmospheric observations and modelling! amos.org.au/amos-2021-call-f…
Happy to see this out in ACP - well done to Luke and his hard work!
