Shackleton's infamous ship 'Endurance clearly had several structural deficiencies,' new analysis reveals Ernest Shackleton's ship, the Endurance, infamously sank in Antarctica — and now a new study finds that it had known flaws.

The infamous ship Endurance, which sank in #Antarctica in 1915, wasn't as well built for a polar voyage as previously thought — and its owner was likely aware of its shortcomings via @livescience.com

The Beyond EPICA project extends the ice core climate record by 400,000 years, helping us to understand long-term climate patterns and improve future predictions.

When it comes to storing carbon, the Arctic presents a winter surprise The ocean holds gigantic amounts of carbon, much more than all land-based plants and soil. Scientists previously studied these carbon stocks in spring and summer. Now, in two published studies, they h...

"It shows that the carbon cycle is active even in winter. (...) It is important because the ocean is getting warmer, and thus the entire balance can change. Warmer seas mean that seasonal variations can also be different" #Arctic
