To add to that picture, this study found that elephant seals migrated to the Victoria Land Coast in the Ross Sea about 8000 years ago, as the region became warmer, and stayed there till about 1000 years ago when sea ice returned.

During 1992–2016, the AIS changed from a positive mass balance of over 100 Gt a−1, which was reducing sea-level rise by 0.3 mm a−1, to a state of balance close to zero by 2014. The mass balance successively changed...

He added: "The possibility of Pine Island Glacier entering an unstable retreat has been raised before but this is the first time that this possibility is rigorously established and quantified.

Heating of the Tasman sea warms up the climate of Antarctic Peninsula via changes in wind patterns, new study by Japanese and Australian scientists shows RESEARCH ORGANIZATION OF INFORMATION AND…

PENN STATE Research News When a block of ice the size of Houston, Texas, broke off from East Antarctica’s Amery Ice Shelf in 2019, scientists had anticipated the calving event,…

That meltwater forms strong coastal currents and ocean fronts, and those currents are impacted by winds, tides, and break down if they become unstable...

Guest Post by Renee Hannon Introduction This post examines CO2 data collected in Antarctic firn and its journey as firn transitions to ice where CO2 is eventually trapped in bubbles.…

Antarctica's next deep ice core, drilling down to ice from 130,000 years ago, will be carried out by a multi-institutional U.S. team at Hercules Dome, a location hundreds of miles from today's coastline and a promising site...

Warm, moist rivers of air in Antarctica play a key role in creating massive holes in sea ice in the Weddell Sea and may influence ocean conditions around the vast continent as well as climate change, according to Rutgers...

Some years ago, relating to a project I was carrying out, I asked the Max Planck Institute and Cambridge University –both experts in this field-if it were possible that Antarctic ‘ozone hole’ -actually a ‘thinning’...

From the “that darned sea ice is messing up our model” department and MIT News. Study suggests sea ice blocks the flow of carbon both into and out of the ocean, in roughly equal measure. The Southern Ocean surrounding...

Emperor penguin (Aptenodytes fosteri) populations in 2019 were found to have grown by up to 10% since 2009 – to as many as 282,150 breeding pairs (up from about 256,500) out of a total population of over 600,000 birds (Fretwell...
