Sea Ice Floe Segmentation in Close‐Range Optical Imagery Using Active Contour and Foundation Models Gradient vector flow active contours are compared with the Segment Anything Model to segment sea ice floes in close-range optical imagery The Segment Anything Model guided by prompts provides rob...

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.

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

This is Australia’s only icebreaker. Here’s why experts say we need another

A parliamentary report has called on for a second icebreaking vessel and more reliable funding for Antarctic research.
