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.

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.

🌀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. 2025 ozone: @copernicusecmwf.bsky.social

💪 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.
