OMG watch this cute sea pig! :BlobhajHeart: And all the other photos from a secret part of the ocean: theguardian.com/environment/ga We need to protect this #biodiversity!
Deep sea habitats are threatened by mining plans.

the Guardian · Sea pigs, icefish and trilobites: Antarctica’s mysterious marine life – in picturesCharacterised by darkness and cold temperatures, the extreme environment of Antarctica’s deep sea is largely unexplored. Now, after a special marine science voyage, a team aboard Australia’s national icebreaker, RSV Nuyina, has collected some remarkable species from the waters around the Denman Glacier

And to download the actual sea ice data including indices for both #Arctic and #Antarctic from @osi_saf check out the links here which @lavergnetho just shared again:

Ruth_Mottram - Good morning! Quick reminder that you can see the current state of the #Arctic #SeaIce on @polarportal where you can also see how the # Greenland Ice Sheet mass budget from GRACE and the daily surface mass budget from @dmidk  Some big improvements + new data coming soon too

On the other side of the globe, #Antarctic sea ice is beginning to rapidly expand as austral winter approaches. Last month observed quite a bit of regional variability in this area too, though it was generally below the 1981-2010 mean.

Satellite-derived data provided by the National Snow and Ice Data Center (NSIDC).

Two polar stereographic maps side-by-side showing Antarctic sea ice concentration and its anomalies relative to 1981-2010 for April 2025. Red shading is shown for less ice, and blue shading is shown for more ice. More areas are below average than above. Antarctica is masked out in grey shading.

We tracked a krill super trawler deep into #Antarctic waters and caught something on camera they would have rather kept hidden from the world.

It reveals how industrial fishing can continue non-stop in one of the most remote and fragile places on Earth - endangering a vital ecosystem that should be protected.

Watch the full video now and take action to #StopThePlunder with our Krill Toolkit. (http://savekrill.com/)

Protest March of the Penguins
youtube.com/watch?v=Xlik9QF08q

"Trump slapped 10 per cent tariffs on an Australian territory with no human inhabitants: the Heard and McDonald Islands, home to #penguins and seals. In response, nonprofit Penguins International will livestream the #Antarctic penguins’ annual #migration from the ocean to their breeding grounds, calling the event the ‘Protest March of the Penguins.”"

This is a story of a separation that lasted a year, with #Antarctic icebergs and airstrikes lying between them.

They are a young married couple — #Roman and #Ivanna_Koturbash. He has been a military doctor at the #Pokrovsk hospital, saving the lives of #Ukrainian soldiers since 2021, and she became the doctor of the 29th #Ukrainian Antarctic Expedition

40 years ago today RRS Discovery III arrived at Montevideo, marking the end of my first #Antarctic and Southern Ocean research cruise. The ship had been my home for four and a half months, since 23rd November. Part of me wanted to head home, but I couldn't pass up the opportunity to explore some of the sights of South America, so my adventure continued.

Here, using an Earth system model with interactive Antarctic ice-shelf cavities, we show that regional hydrography and topography determine a cavity tipping point. The Filchner–Ronne ice-shelf cavity will encounter such a tipping point with abrupt warm-water intrusion, rapid basal melt increase and massive freshwater release in response to increasing CO2 levels within this century. Conversely, the Ross Ice Shelf shows a more gradual response

NatureRegional conditions determine thresholds of accelerated Antarctic basal melt in climate projection - Nature Climate ChangeMelting from below is crucial for the future evolution of Antarctic ice shelves. Here the authors use an Earth system model with explicit simulations of ice-shelf cavities to show how regional hydrography and topography determine when an ice shelf will undergo rapid melting.
