New study led by South African scientists reveals how sea-ice #microbes survive the #SouthernOcean’s harsh winter, with implications for #climateChange
This study further reinforces the importance of the Southern Ocean marginal ice zone as a critical hotspot for global #sulfur cycling where #biogeochemical processes for climate regulation are enhanced.

In a new study scientists reveal up to 38-fold higher DMSP concentrations in Southern Ocean sea-ice versus the surrounding seawaters during the Southern Ocean austral winter. DMSP is known for protecting organisms against environmental stressors. Its degradation yields dimethylsulfide (DMS) and methanethiol (MeSH) which are important climate-cooling gases. The study underscores the role of this seemingly uninhabitable environment as a dynamic reservoir and transformation hub influencing climate-cooling cycles in the polar region.

Cape Horn remains one of the most legendary maritime landscapes on the planet.
“The planet has transformed as #HumanActivities alter the texture of our land as seen from space, expanding cities, #clearing dark #forests
for replacement by bright agricultural lands and contributing to the desiccation of the Aral Sea which has shrunk to less than 10% of its 1960s size."
“Some of that change can even be seen in the images themselves, even though the Earth is shrouded in cloud. "Although they're of different parts of the Earth, the one thing that does show up in both images, although you're looking at different parts of it, is Antarctica and the #SouthernOcean," says #BenjaminWallis, a glaciologist at the University of Leeds in the UK. "The #Antarctic Peninsula is one of the most rapidly warming parts of the #Earth and 28,000km of ice shelf have collapsed in between the original image and the latest image."

Hao Huang et al.* see how the CALIPSO satellite observations can be used as a phytoplankton biomass proxy, and how they can be integrated into air-sea CO₂ flux estimates in the Southern Ocean.
