Antarctic krill head south – Australian Antarctic Program: Some populations of Antarctic krill are shifting south, closer to Antarctica, as ocean warming and sea-ice changes alter their habitat. https://lnkd.in/eh4jTh76

📉 Global sea ice extent is at a record low for this time of year, new data reveals. This is due to rapid Antarctic sea ice melt and below-average Arctic coverage. 🗓️ Antarctic sea ice extent has been tracking at record-low levels for almost the entire year, making headlines around the world. 🗣️ One expert tells Carbon Brief Antarctic conditions this year have been “truly exceptional” and “completely outside the bounds of normality”. For more detail on this new data, read Ayesha Tandon’s article here ⬇️ https://bit.ly/3Q1jhBl #Antarctic #SeaIce #SeaIceMelt #ClimateChange #ClimateScience

😱An epic account of serpentine-like beings using their thin, long limbs that can grow up to 60 cm long to crawl across the Antarctic seafloor. They won't hesitate to break off an arm to escape predators. And what's even more chilling is that the arm will then grow back. 😱 Are the hairs on the back of your neck standing up yet?? The Antarctic Ocean Commission already has the power to create sanctuaries in Antarctic waters NOW. Urge them to take the first steps towards protecting at least 30% of our oceans by 2030, because a starless ocean is more petrifying than you think. 👉🏾 https://act.gp/40lSeo5

One of the world’s largest icebergs is drifting beyond Antarctic waters, after being grounded for more than three decades, according to the British Antarctic Survey. #iceberg #antarctic #antarctica #environment #climatechange #climatecrisis #climateemergency #globalwarming #globalheating

In this video by NCI VizLab of ice-ocean dynamics near the Denman Glacier, you can see the offshore eddies spinning the Antarctic sea ice; the sea-ice factories of open water near the coast called ‘polynyas’; the smaller-scale near-shore ocean movements where it’s shallower; and the sea ice torn apart by wind and currents. This high-resolution computer simulation is generated with the MIT General Circulation Model by University of Tasmania, CSIRO and ARC Australian Centre for Excellence in Antarctic Science. To model processes as complex and inaccessible as #Antarctic ice-ocean dynamics needs the superpowers of the National Computational Infrastructure.

Deep in #Antarctica❄️, the #HalleyVIResearchStation🇬🇧is the headquarters of the British Antarctic Survey. The six comes from the fact that five other Halley Research Stations have fallen prey to Antarctica’s inhospitable environment. This is one of the few structures that wasn’t built on location. #Britain🇬🇧 prefabricated and tested them in #SouthAfrica before shipping them to Antarctica. Portability is vital because they set up Haley VI Research Station on the Brunt Ice Shelf, which is quickly moving towards the ocean. The British Antarctic Survey’s scientific research center Halley VI was designed to withstand temperatures of -50°C, to be self-sufficient for months on end and, should danger strike, to move locations quickly. The research conducted at Halley VI has had far-reaching impacts. The long-term research led to the discovery of a hole in the #Ozone layer in 1985. This significant finding has shaped global environmental policies and strategies for decades. The base has even been used to help the European Space Agency, by testing out what it’s like to live and work in a place that is very isolated. #AntarticSpecialOpsSAS🇬🇧

Is Antarctica Sending Us a Dire Warning? New Study Sounds the Alarm on Sea-Level Rise 🌊 Could our coastal cities be at greater risk than we thought? Recent research out of the British Antarctic Surveys unveils shocking truths about the 'unavoidable' melting of the West Antarctic Ice Shelves. 👇 From why this spells danger for hundreds of millions globally to what this means for future sea levels, our blog article delves deep. 🔗 Click the link below to unlock the unfolding story. https://lnkd.in/gGANzsTg #Antarctica #sealevelrise #climatechange #urgentaction

The face of Antarctica is continuing to change, with record-breaking declines in sea ice levels compromising our understanding of polar processes. This understanding is vital in helping us interpret our changing climate and ecosystems. As a result, scientists are calling for greater capabilities to be added to Antarctic ice modelling, including high-resolution satellite imagery to measure ice drift and remote sensing of ice and snow depth. Read more about the call for grater situational intelligence tools, and the real-world benefits it will bring to Antarctic research and our understanding of changing climates, in the full article below: https://hubs.ly/Q025P2Ns0 #SituationalIntelligence #SituationalIntelligenceTools

As has been well documented, #Arctic #seaice has steadily #declined in #extent and #thickness since the 1980s. Sea ice in the #SouthernHemisphere, however, has tended to behave differently to its Northern counterpart. As covered in the newly published #StatoftheOceans 2024 report, a collaboration between #Statista and the #GermanOceanFoundation: "Despite the rise in global #seasurfacetemperature, the #Antarctic was showing to be more resilient to such changes. Nonetheless, this pattern seems to have reached a #tippingpoint." As illustrated in this infographic, #seaicecover extent in Antarctica reported record low levels in 2023. Particularly in #winter, when the sea ice area is at its highest, #icecover drifted drastically away from the average. While a strong #ElNiño phenomenon in 2023 may have caused the abnormal reaction, "researchers are already arguing if this is a temporary effect or if we are at the beginning of a new regime for the #Southernicesheet." https://lnkd.in/gAVcsrXj
