| Simultaneous ice melt in Antarctic and Arctic Posted: 02 Dec 2011 12:55 PM PST A new article shows that the two hemispheres attained their maximum ice sheet size at nearly the same time and started melting 19,000 years ago. This simultaneous melting was presumably caused by changes in the global sea level and deepwater circulation in the Atlantic Ocean. |
| Where Antarctic predatory seabirds overwinter Posted: 02 Dec 2011 06:10 AM PST When it comes to choosing their wintering destinations Antarctic skuas are flexible. According to a new study, a great part of the South Polar skuas spend the Antarctic winter in the Northern Atlantic. At the same time about one third of the same species overwinters in the Northern Pacific, tens of thousands of miles away. |
