The smiles say it all - they've finally made it to the ice! After an extended stay in Christchurch due to weather delays, followed by an 8hr boomerang back to Christchurch, the first of our science team have landed in Antarctica.

Happy Antarctica Day! 💙
1 December is the anniversary of the signing of the Antarctic Treaty in 1959.
Australia was one of 12 original signatories to the Treaty, which established #Antarctica as a "natural reserve, devoted to peace and science".

Antarctica Day marks the anniversary of the signing of the Antarctic Treaty, setting the foundation for international collaboration in Antarctic research. SWAIS2C brings together researchers from 10 countries, dedicated to understanding how Antarctica’s ice sheets will respond in our warming world.

Happy Antarctica Day! We’ve recently updated this map to show consultative and non-consultative signatories of the Antarctic Treaty, signed on this day in 1959. The Treaty designates Antarctica a continent for peace and science. December 1st raises awareness of this global agreement and its goals.

It’s Antarctica Day! Give it up for this articulated skeleton of Thrinaxodon, an early mammal relative from 250 million years ago, found in the Transantarctic Mountains 8 years ago. This continent has an amazing fossil heritage that we’re continuing to learn more about!

MYIC drilling team landed at Dome C earlier today. We are one day behind schedule, which in the face of logistical and weather challenges of operating in Antarctica is a big WIN!!
Two months ahead of us for deep drill set up and ice coring. Bring it on!!

10/ But we have choices. Under high emissions, a positive SAM continues to strengthen. Under low emissions pathways where net zero is achieved, modelling shows the SAM could stabilise by 2050 and begin returning to its historical range by 2100.

8/ The implications for sea-level rise are less clear. Ocean circulation changes could accelerate melt in the cavities underneath ice shelves that buttress the Antarctic ice sheet, while SAM-driven increased snowfall in some regions may offset ice mass loss.

7/ A persistent positive SAM is expected to reduce the Southern Ocean’s ability to absorb excess carbon dioxide, warming the climate. Stronger, southward-shifted winds create upwellings that release more carbon from the deep ocean into the atmosphere.

🌀 2/ The effects of the SAM connect the stratosphere to the ocean, and Antarctica to the tropics. In the Southern Ocean, it drives the Southern Westerly Winds (SWW) which drive the Antarctic Circumpolar Current, the world’s strongest current surrounding Antarctica.

9/ “Given the importance of SAM effects on Southern Ocean circulation, carbon cycling, and Antarctic ice mass balance for future climate and sea level rise projections, it is crucial that the effects of SAM are better modelled and understood,” the review says.

🌊 1/ Meet SAM.
The Southern Annular Mode (SAM) is the Southern Hemisphere’s most influential #climate driver. When the SAM enters a positive phase, the westerly winds tighten and move towards #Antarctica. When it moves into a negative phase, these winds expand back towards Australia.
