But you've forgotten to say that the ones on the upwind side get cold quicker and move into the middle more often. This means that over time the huddle moves downwind. Usually leaving a big brown stain behind them . This stain is what we see on satellite imagery and what we use to find them. 😁
Emperor penguins were just declared endangered by IUCN.
In the face of climate change, these beloved penguins have been losing the sea ice they need to survive.
This is another urgent warning that the world needs to end our reliance on fossil fuels.
Thanks, glad that you're enjoying it, it was great fun to write!
Passed my viva and (pending minor corrections) am a “Dr of Seals”!
Thanks to my supervisors @ptfretwell.bsky.social and Gareth Rees for guiding me to this stage.

The new island that I found last month have now officially been named Magic Islands, after the Mapping and Geographic Information Centre in British Antarctic Survey where I work.
Copernicus Browser link from 31st January this year:

Discovered in Copernicus browser. I'll post the link later
By satellite. It has not yet been visited. It appears snow covered in earlier maps. So I doubt if anyone has seen it by eye yet.

@bsky.app This weeks Antarctic discovery: The largest lake on the Antarctic Peninsula.
Unnamed, as it only deglaciated over the last decade. It's on a place called View Point on the Eastern side of the Peninsula. There are other larger lakes in the region, but this is the largest on the mainland.
🐧❄️🧪🌏🦑🦉 New publication! Led by @rosetazetta.bsky.social, we used satellite imagery to study Ross Sea #emperorpenguin populations over 20+ years & found that spring colony attendance is closely linked to sea ice conditions. Learn more: shorturl.at/joLZA
In new research, @ptfretwell.bsky.social @bas.ac.uk discovered emperor #penguin molting sites in satellite images—sites threatened by the disappearance of sea ice. 🐧🧊🧪

Hello Walrus-spotters of Bluesky!
Meet Dr Hannah Cubaynes, who is leading the Walrus from Space citizen science counting project.
Help count here ➡️ geohive.vantor.com/walrus/login
Watch Hannah's talk about her (prize-winning) work tracking animals with satellites 👇

If your in London tomorrow come along to the Shackleton Store to hear about "Penguins in Peril" and the Penguin Book of Penguins at a free event.https://shackleton.com/pages/events
Bluesky, we need your help to count walrus! 🦭
Previously on "Walrus from Space", volunteers like you sifted through around 500,000 satellite images to support our conservation research.
Now we're asking the you to help us count the walrus in those images 👀

I can announce that my Antarctic Atlas will be re-issued in paperback in September. I am just in the process of reviewing a retrospective work on the first ever Atlas of Antarctica published by the USSR 60 years ago. It took 10 years and 265 scientists, cartographers and reviewers to compile it!

Rather too small for official names; but now maybe "Fretwell Islands"👍

You might think that we have the world pretty well mapped. But Antarctica we are still finding new islands. Here are the locations of five islands and a larger island groups I discovered last week!
Scientists have discovered that the shrinking sea ice in the Antarctic force penguins to crowd into smaller patches of stable ice to moult.
On #WorldWildlifeDay, explore how researchers from @bas.ac.uk are studying this phenomenon using satellites imagery: bit.ly/40K4iQI
Check compare visualization here: link.dataspace.copernicus.eu/w2h6 (Antarctica is covered by Extra-Wide Swath data, you have to choose HH+VV polarization in the Browser, and use HH Decibel Gamma to see ice and open water)
The ice shelf connecting Rothschild Island to Alexander Island has disintegrated. 100 km2 of shelf, a remnant from the Wilkins Ice shelf, broke up on the 1st March, making an 11km wide channel between the two islands. Images from Sentiel-1
