#Antarctic sea ice is nearing its annual maximum extent (austral winter). This year will not be setting any new records, though there are plenty of regional extremes as shown in August's anomaly pattern.

Less #UVlight may mean less carbon storage in Antarctic tundraThe #Antarctic ozone layer is recovering, a major environmental success following the #MontrealProtocol. As the #ozone layer heals, less #ultraviolet radiation reaches the Antarctic surface—a change usually viewed as beneficial for living organisms.
But a new field study suggests that the ecological story may be more complicated. -

#Bacteria found to produce #proteins that act like #antifreeze, helping marine #worms survive in polar waters
https://phys.org/news/2024-06-bacteria-proteins-antifreeze-marine-worms.htmlResistance to freezing conditions of endemic #Antarctic #polychaetes is enhanced by cryoprotective proteins produced by their #microbiome https://www.science.org/doi/10.1126/sciadv.adk9117
"The finding showed that the worms and bacteria had formed a symbiotic relationship—the bacteria got a home in the worm and a food source, and the worms avoided freezing to death."
-
Close relatives of earthworms, polychaetes are some of the most common #animals on the #ocean floor, but how these species survive the low temperatures of #Antarctic waters has been a mystery.
Other Antarctic species, like icefish, make their own #antifreeze proteins, but most Antarctic organisms do not produce these proteins.
Antarctic marine worms survive with a little help from their bacterial friends.
