Like a sunflower sea star, with its 24 arms reaching across 3 feet or more, ocean organizations are working together to save this beautiful invertebrate. Not only for its beauty, its vibrant colors ranging from purple to orange and yellow, but because…
Research indicates that diminishing Antarctic sea ice since 2015 has significantly increased ocean salinity, affecting water mass dynamics. Antarctic Intermediate Water (AAIW) has grown saltier and denser since 2015, according to a study by researchers from the Indian Institute of Science, the…

[Dale Andersen]: Hi Keith, A quick note while the base WiFi is up and running. We spent the last two days digging out the entrance to our hut, removing snow that migrated inside over the winter, and getting the snowmobiles…

Updated - October 28, 2026 07:49 pm IST - Bengaluru A new study has revealed that the Antarctic Intermediate Water (AAIW), a major water mass that carries the influence of the Southern Ocean into subtropical oceans, has become saltier and denser since 2015. The study, carried…
During the last ice age, a floating ice shelf filled Baffin Bay and helped hold three ice sheets in place. Its collapse may hold a lesson for Antarctica. An ice shelf floats on the ocean, so it’s easy to treat…
a vast layer of fresh water spanning much of the Southern Hemisphere's ocean - has rapidly reversed its long-term trends in salinity and density, according to new research. The AAIW helps store carbon, supply oxygen and drive global ocean currents. The…
Perennial cave ice in the temperate zone is declining, and its monitoring requires suitable change-evaluation methods. This study compares three approaches to assessing the changes of a vertical ice wall in the Ruffínyi Corridor of Dobšiná Ice Cave (Slovakia), a…
Earth’s persistently frozen poles mean the last ice age never really came to an end. What we think of as the mammoth-romping, Neanderthal-stomping chapter of geological history was technically a glacial maximum, one our planet would now be returning to…
