Anomalies in #Antarctic sea ice concentration show the monthly variation from the long-term mean. This map from nilas.org shows more ➖ than ➕ anomalies for June. See the lack of sea ice in Bellingshausen Sea (arrowed), almost at summer ice levels in mid-winter! 
This map from @NSIDC and @NASAEarth shows sea ice concentration on 17 June. The orange line is the typical extent for that day based on the average from 1981 to 2010. Some coastal regions are now ice-free where that has not been observed before.
The last decade has seen increased variability. Sea-ice area reached a record low in Feb 2023 following the previous record low in Feb 2022, and an extremely low summer avg in 2016/17. Is this shift in Antarctic sea ice a response to climate change? We need to find out @IPCC_CH.

The location of Rio Grande is of extreme strategic importance and crucial for the world in general.

2/“By drilling into sediment cores 100s of feet beneath Antarctica’s sea floor, scientists discovered that during previous periods of global warming—3M & 15M yrs ago—loose sediment layers formed & slipped, sending massive tsunami waves to the shores of S America, NZ & SE Asia.”
3/“Weak layers beneath 3 submarine landslides, consist of…oozes & glaciomarine diamicts. The lithological differences, from glacial to interglacial variations in biological productivity, ice proximity & circulation, caused changes in deposition preconditioning slope failure.”

Each spring in the Southern Ocean, sometimes seen from space by @NASA satellites, swirling blooms of solar-powered phytoplankton turn CO2 into food for everything else. While we know the blooms are critical to the biological carbon pump, what triggers them is up for debate.

They use data from 7114 profiles from 56 BGC-Argo floats circling #Antarctica to measure the biogeochemistry of the Southern Ocean south of 60°S, like this by @SOCCOMProject. See how the @bgc_argo float rights itself in the water, ready to start a mission of at least 3 years.

🫁 It’s like you can see the oceans breathing. As seasons change, chlorophyll levels from tiny marine plants ripple around the planet. Phytoplankton use chlorophyll to absorb carbon dioxide to make food. This @NASA map gives insights to the oceanic carbon cycle. Read on...🧵

🔃 Crucial for ocean carbon cycling is the 'biological pump', where carbon is taken from the atmosphere by life and put into storage in the deep. It turns out that tiny phytoplankton in the @_SouthernOcean play an outsized role in stopping the planet from overheating.

🌊 The Southern Ocean is central to slowing the rate of global heating. It accounts for about 40% of the ocean's annual absorption of human-made carbon! So to understand its role in global climate, we really need to understand the influence of biology on this carbon sink (C).

#Ukraine: Today's news from #UkraineWar: 1. UA forces yesterday pushed back RU troops on Korsunskogo Street in #Bakhmut using a charge fired from UR-77 Meteorit mine clearing vehicle, at least 13 of which have been captured from RU. Devastating! #tweet100
#Ukraine: 2. UA came under 70 attacks by RU yesterday, 32 of them in #Bakhmut. UA E Command said "building" #Prigozhin "installed" his flag on had long been destroyed. The flag was "dedicated" "Good Memory to Vladlen Tatarsky," the mil-blogger killed in St. Petersburg. #tweet100
#Ukraine: 3. Brutal battles taking place on N & S edges of #Bakhmut & fighting nr stadium. RU assaults repelled at #Ivanivske & #OrikhovoVasylivka. Intense at #Bohdanivka. #tweet100 (Map: @ChuckPfarrer)
#Ukraine: Today’s reports from #UkraineWar: 1. Graphic from @nytimes overlaid on ISW map shows how much of #Bakhmut UA still holds. After costly attacks, Wagner have taken #DubovoVasylivka but were repelled at #OrikhovoVasylivka nearby. UA advancing to SW of city. #tweet100
#Ukraine: Today’s news from #UkraineWar: 1. Reports from #Kreminna that local residents are being evicted from their homes to accommodate RU troops, dispersing them so they are not vulnerable to UA attack in 1 large building. #tweet100 THREAD
#Ukraine: 2. UK Intel says RU forces Minister of Defence, Shoigu, reported to have visited RU frontlines this week in a rare visit, perhaps prompted by all the visits from Wagner’s #Prigozhin. Future RU strategy not clear - even for them! #tweet100
This may look like a very ordinary seascape, but it isn't. This view is at 72°S in the Bellingshausen Sea, #Antarctica, taken from RV Polarstern expedition #PS134. In a normal year there would be a lot of #seaice in this area, but this year there is none. 1/3
@AWI_Media @BAS_News This month has seen a new record minimum in #Antarctic #seaice extent since satellite records began more than 40 years ago. In the Bellingshausen Sea most of the ice was gone by the end of November. 2/3
@AWI_Media @BAS_News The minimum #seaice extent is highly variable from year to year, and we should be cautious about reading too much into a single year. However, #Antarctic annual and summer sea ice extents have now been below the long-term average for 7 years. A trend seems to be emerging. 3/3
These three little penguins have no idea what an adventure they are about to have! Follow me to follow them. #Antarctica

Penguins found the Cristal sign at Santiago airport, getting closer!
Around 3,400 million years ago, the peninsular ‘gneiss’ came out and was cooled from volcanic activity.
This is what formed the city’s bedrock today. But the rock itself weathered and stored water in shallow aquifers.

Bengaluru as we know it today, settled at the fag end of the Deccan plateau, 900 metres above sea level.
This gave it the #pleasant climate that Bengaluru is famous for.
Let’s now skip to 88 million years ago. >>

Huge congratulations to @Endurance_22 and @NatGeo for finding the wreck of #Shackleton’s #Endurance. The wreck is amazing but can we also talk about some of the #Antarctic sea floor creatures that now call it home! Add any others you spot to the thread! (1)
Huge #Antarctic sea anemones (Hormathia or similar) dangle their tentacles in the icy water! All of the animals that I have spotted so far are filter feeding! (2)
Sea squirts pump water in and out through their two syphons to collect plankton and marine snow (dead things and poo raining down from the surface). (3)
Australian Prime Minister @ScottMorrisonMP made the judgment that #China does not “share the same objectives as Australia does” in #Antarctica .
If he meant the objective of creating harmful political tension among parties or countries conducting scientific exploration on the continent, then he is right---#China does not intend to do that.
In 1984 when China sent its first fleet of science experts to the #Antarctica , Chinese leader Deng Xiaoping set out China’s mission as “to contribute to humanity’s peaceful use of Antarctica”, the principles of which #China has adhered to over the years.
