Hardest working ocean on Earth you’ve never heard of. Doing the heavy lifting to suck up carbon and heat, and you know, just keep the planet liveable. You’re welcome.

An excellent plan by excellent people
The East Antarctic continental shelf is central to the #climate system yet remains one of the most poorly known regions of the global ocean.

So #Antarctic scientists in Japan and Australia have produced this ambitious forward-looking research plan.

💪 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.

🌀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.

🌨️ Clouds over the cold Southern Ocean are different from elsewhere. Here they're seeded not by aerosols from land, but from the ocean—and even life itself.

1️⃣ In shelf waters close to #Antarctica, the annual freezing and thawing of sea ice presents a natural barrier to the measurement of crucial ocean properties like temperature and salinity. 🌊

1️⃣ Antarctic Bottom Water (AABW) is the densest water mass in the world ocean due to its high salinity & cold temperatures. Filling the abyss, it accounts for up to 40% of oceanic volume. It plays a vital role in moving cold water toward the equator and regulating global climate.
