Ozone thinning has influenced ocean circulation

The hole in the Antarctic ozone layer has caused changes in the way that waters in those southern oceans mix, which has the potential to alter the amount of CO2 in the atmosphere and eventually could have an impact on global climate change, according to earth scientist

Retreat of Crane Glacier on Antarctic's Larsen-B ice shelf

Hektoria and Crane glaciers on the Antarctic Peninsula have continued thinning since the Larsen-B ice shelf’s collapse in 2002.  They are considered to be among some of the fastest changing in recent years. Almost the entire Larsen B Ice Shelf splintered and

Are we facing an end of Antarctic as we know it?

Regional warming, over-fishing, pollution, invasive species creeping into the area, ocean acidification and loss of sea ice around South Pole region are the most immediate threats for waters around Antarctic. And all those threats are linked to global levels of carbon

Unusual blue-green mass in Mackenzie Bay, Antarctic

Off the northeastern edge of Antarctica’s Amery Ice Shelf lies Mackenzie Bay, which was painted with a ghostly blue-green mass in early February 2012. Icebergs sometimes interrupt flow of similarly colored tendrils northward across the ocean. Multiple factors

Lake Vostok - Subglacial drill projects at Antarctica

Antarctica has nearly 90% of the ice and 70% of the fresh water on Earth. The third-largest continent, it is one and a half the size of the US.  More than 150 subglacial lakes have so far been discovered beneath Antarctica’s vast ice sheet. These lakes
