1/ More than 600km above 🌏, NASA's PACE (standing for Plankton, Aerosol, Cloud, Ecosystem) satellite is in a polar orbit. Covering the globe in about two days, it gathers data on ocean colour, aerosols, and clouds enabling the study of climate change and ocean ecosystems.

🌊⚠️ "Understanding and predicting marine-terminating glacier instability presents one of the greatest challenges to forecasting future sea level rise" — case of the Hektoria Glacier in #Antarctica, which retreated ~25 km from Jan 2022 to March 2023.

1/ Crabeater seals are the most abundant top predator in the Southern Ocean and probably the most numerous large wild mammals on earth. Because they live almost their entire lives amongst floating sea ice around #Antarctica, it’s difficult to count them – total population is an estimated 15 million.

Antarctic Geopolitics: Russia’s arrest of Ukrainian Antarctic Scientist directly linked to its ambition to mine in Antarctica. I’ve seen the prosecution document: it’s outrageous.

Russia's interest in Antarctic oil exposed after scientist's arrest
A document linked to the arrest of a scientist has raised questions about whether Russia has long-term ambitions to exploit oil resources in Antarctica, where mining is banned indefinitely.

In our annual workshop this week, a hundred or so enthusiastic AAPP-ers spent two great days discussing our research so far and where we need to take it, to fully explore the pivotal roles of #Antarctica and the Southern Ocean in the global #climate system.

Recent research shows low sea ice is changing #phytoplankton bloom timing and composition in the Southern Ocean.

“Phytoplankton are the ocean’s version of the Amazon rainforest,” says ACEAS lead author Tamara Schlosser from @utas.edu.au.

🌀The stratospheric polar vortex is a belt of high-speed cyclonic winds around 12-20km high over the poles. When temperatures in the stratosphere – which contains the ozone layer – start rising in the southern spring, the ozone hole over the Antarctic grows.

💪 A superpower of the Southern Ocean is taking up heat and carbon from humans and slowing the rate of global warming, by exchanging heat and carbon between the atmosphere and the deep ocean.

🔄 The freeze-and-melt cycle of sea ice drives this exchange by changing water density and acting as a pump.

Proposed "geoengineering" projects designed to reduce the impacts of global warming in polar regions would be ineffective, extremely costly and environmentally dangerous, researchers have warned.
