  1. #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 tundra

    The #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.

  23. #Bacteria found to produce #proteins that act like #antifreeze, helping marine #worms survive in polar waters
    phys.org/news/2024-06-bacteria

    Resistance to freezing conditions of endemic #Antarctic #polychaetes is enhanced by cryoprotective proteins produced by their #microbiome science.org/doi/10.1126/sciadv

    "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."

  24. 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.

  30. "The West Antarctic Ice Sheet is the continent's largest contributor to rising seas and contains enough ice to increase the global mean sea level by over 17 feet, the study explains" commondreams.org/news/west-ant Anyone got a map of how Dublin would look with a 5 metre sea rise? #Antarctic #SeaIce #SeaRise #Dublin

  31. The ocean sector offshore of Queen Maud Land in #Antarctic lacks about 1 million km² of sea-ice cover compared to normal conditions.

    The sea-ice extent has been dropping fast the recent days...📉

  32. For a week, September 12th has marked the date with the largest #Antarctic #seaice extent in 2023.
    This is absolutely record-low for an Antarctic maximum extent!

    This still can change and we hope it will 🤞

  33. No surprise. But still crazy.

    #Antarctic #SeaIce extent is low.

    This graphic shows the ranking of sea-ice extent by month. Take a look at the last line (representing 2023 and updated including August).
