Tiny ocean migrants play a massive role in #SouthernOcean #carbonStorage
A groundbreaking study has revealed that small but mighty #zooplankton—including #copepods, #krill, and #salps—are key players in the Southern #Ocean’s ability to absorb and store #carbon.

Sea ice isn't just frozen water — it's a climate ally. Longer winters mean more carbon stays locked away in the Southern Ocean. #ClimateScience #SouthernOcean #CarbonCycle

This Elusive #Antarctic #Squid Was Seen for the First Time
An expedition in the #SouthernOcean captured video of a rare species of deep-sea #cephalopod. Until now, it had been found only in fishing nets and in the bellies of seabirds.
This particular dive was part of the #NationalGeographic and #Rolex Perpetual Planet Expedition, an initiative to document #climatechange in the mountains, rainforests and #oceans.

Sea pigs, icefish and trilobites: #Antarctica’s mysterious marine life – in pictures https://www.theguardian.com/environment/gallery/2025/may/08/antarctica-marine-life-denman-glacier-rsv-nuyina-in-pictures
"True #trilobites went #extinct more than 250m years ago, but the #SouthernOcean is home to a living lookalike: Ceratoserolis trilobitoides. They have a segmented, armoured exoskeleton, which helps protect them from predators... after a marine science voyage, a team aboard #Australia’s icebreaker #Nuyina has collected some remarkable species from the waters around the #DenmanGlacier"
Laurie C. Menviel et al.* explore the effects of shifting and strengthening winds on air-sea CO₂ fluxes in the Southern Ocean.

Scientists collect unique sea creatures during voyage to East Antarctica https://www.abc.net.au/news/2025-04-03/nuyina-scientists-collect-antarctic-sea-creatures-denman-glacier/105130020
"The RSV #Nuyina is partway through a 60-day voyage to the edge of #Antarctica — it's first mission dedicated solely to marine science... research teams are analysing some of the unique #biodiversity found in the #SouthernOcean. These include #SeaSpiders as big as your hand, #SeaStars that grow to the size of a dinner plate and #octopus species endemic to the region... some could be new to science"
New research links Southern Ocean warming to increased rainfall in East Asia and Western U.S., with effects lasting up to 150 years. #ClimateChange #WeatherPatterns #SouthernOcean

Why Antarctic waters are cooling in a warming world – Earth.com…
For decades, climate models have predicted that the #SouthernOcean surrounding #Antarctica should be warming in response to global #climatechange. But surprisingly, real-world data show something different: much of that ocean has actually cooled over the past forty years....

Sand-sized fossils hold secrets to the history of climate change…
Between 18,000 and 11,000 years ago, the amount of #carbondioxide in the #atmosphere suddenly shot up. This caused rapid global warming, the mass melting of #glaciers, and the end of the last ice age... #climatechange #globalwarming #photosynthesis #fossils #southernocean #iceage
