Near Antarctica, Saltier Seas Mean Less Ice, Study Finds
A study published Monday in the Proceedings of the National Academy of Sciences found that increases in salinity in seawater near the surface could help explain some of the decrease in Antarctic sea ice that have been observed over the past decade, reversing a previous period of growth.
New research has, for the first time, tracked ice shelf, sea ice and ocean swell wave conditions over multiple years in the lead-up to three large-scale iceberg "calving" events in Antarctica, ...
Bedmap3 is the most fine-grain map to date of the landscape beneath Antarctica's ice. Scientists created it using more than 60 years' worth of data from satellites, ships and dog-drawn sleds.

The Antarctic ice sheet, which covers 98% of the continent, averages around 1.2 miles in thickness, with its thickest point reaching nearly 3 miles, the Australian Antarctic Program reports.
West Antarctica is headed for decades of rapid melting no matter how quickly humans cut greenhouse gas emissions, and 2023 shattered records for missing sea ice around the continent.
Antarctica is the world's great cooling unit. This vital part of Earth's climate system is largely powered by the annual freeze and melt of millions of square kilometers of sea ice around the ...
Osterberg said ice core samples showed ice ages 1 million years ago occurred every 40,000 years. Then about 800,000 years ago, ice ages jumped to occur every 100,000 years.
