Get your abstracts in for EGU - if you’ve done any recent Southern Ocean field work that investigated the connection between clouds and biological activity we want to hear from you!

Our #RVInvestigator sets off today on the longest voyage in its 10-year history to the Southern Ocean and sea-ice edge. The aim of the 60-day voyage is to improve our ability to anticipate the impacts of future climate change. csiro.au/en/news/All/News/20… @Ant_Partnership

PhD alert! With @that_Vancey and the @UGrenobleAlpes I'm going back to my roots of synoptic climatology and precipitation but this time in Antarctica! We have three projects to choose from looking at how extreme weather impacts Antarctica.

AAPP PhD student Zhangcheng Pei is lead author of his first paper, assessing the ability of a climate model to properly simulate clouds over the Southern Ocean. It’s published while he’s at sea, 200nm west of Macquarie Island where his data came from. 🌨️🌊 acp.copernicus.org/articles/…

My first ever paper has been published! In this paper, we evaluated the cloud radiative bias in the ACCESS-AM2 model against the ground-based observations at Macquarie Island. Take a look👇!

How cool are Southern Ocean clouds? Supercool! Check out our article for kids on why these clouds are both supercool and super important! kids.frontiersin.org/article… @FrontYoungMinds @MarcMallet @Ant_Partnership
Why Are Clouds Over the Southern Ocean Super-Cool?

Why Are Clouds Over the Southern Ocean Super-Cool?

When water drops below 0° Celsius, we assume it turns to ice. This is not always true though, especially inside of some clouds over the Southern Ocean. When water exists as a liquid below 0°C, it is...

1⃣ This recent view of #Antarctica is from a satellite that scans the intensity of microwave emission. Why is this important? These brightness temperatures show the e̲x̲t̲e̲n̲t̲ of sea ice. But t̲h̲i̲c̲k̲n̲e̲s̲s̲ of sea ice is notoriously difficult to read from space. 📷 @NASA

I learnt a lot too!! There is so much we can do with machine learning when it comes to existing large data sets and known problems - it can definitely ‘shine a light’ 😂 ☀️ ⛅️ ☀️

🚨 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

Flooding this week has affected important agricultural regions in Victoria. In this Conversation article I write about what it means for agriculture and how farm businesses are adapting to climate change and increasing risks of extremes. #agriculture #climate #adaptation

Farmers face a multitude of challenges in future. Crops and livestock are not only on the line, but also the mental health of rural communities. @ElisabethVogel_ from @UNSW writes on how floods damage farms and what can be done about it. #VicFloods bit.ly/3TA5MHE
