Antarctic sea ice is made of thousands of moving pieces.
New research shows how we can map and measure them from close-range images, even in winter conditions.

Fair winds and following seas to @ippy90.bsky.social, who is embarking on a journey to Antarctica to monitor the state of sea ice using our multi-sensor camera array on RSV Nuyina
We’re off tomorrow on Voyage 1 with the @antarctic.bsky.social 🚢❄️🌊🇦🇶
On the RSV Nuyina, our cameras will capture key #ocean & #seaice properties to understand how sea ice forms, melts, and interacts with the climate system. Stay tuned for updates!🐧🧊 @atoffoli.bsky.social @pxh.bsky.social

We spent the weekend in beautiful Hobart retrieving data from our camera system on RSV Nuyina. Exciting sea ice data recorded! Looking forward to new data from the next voyage to Denman Glacier ... Thanks to Dr F. Nelli, @pxh.bsky.social and @antarctic.bsky.social

A parliamentary report has called on for a second icebreaking vessel and more reliable funding for Antarctic research.
This is Australia’s only icebreaker. Here’s why experts say we need another
