Ozone Layer Showing Signs of Recovery, Study Finds
Finally, some good news about the environment. The depleted protective ozone layer that has left a gaping hole over Antarctica is showing signs of recovering, a UN panel of scientists said Wednesday. Read more.
Southern Ocean's role in climate regulation, ocean health is goal of $21 million federal grant
The Southern Ocean that encircles Antarctica lends a considerable hand in keeping Earth's temperature hospitable by soaking up half of the human-made carbon in the atmosphere and a majority of the planet's excess heat. Yet, the inner workings — and global importance — of this ocean that accounts for 30 percent of the world's ocean area remains relatively unknown to scientists, as dangerous seas hinder observations.

Antarctica's sea ice expands at record pace
In the blue half-light of the Antarctic autumn, a thin film spreads across the continent’s coastal waters. It’s an embryonic form of sea ice: a mush of microscopic crystals that floats on the dense, salty water of the Southern Ocean. Read more.
Antarctic sea level rising faster than global rate
A new study of satellite data from the last 19 years reveals that fresh water from melting glaciers has caused the sea-level around the coast of Antarctica to rise by 2cm more than the global average of 6cm. Read more.
Japan seeks to resume Antarctic whaling next year
TOKYO — Japan is seeking international support for its plans to hunt minke whales in the Antarctic Ocean next year by scaling down the whaling research program the U.N. top court rejected earlier this year, fisheries officials said Wednesday. Read more.
The first complete atlas of marine life in the Southern Ocean
After weeks of going through dusty boxes of old notes and sheltering from sub-zero temperatures and wild winds, hundreds of scientists have produced a world first: 'The Biogeographic Atlas of the Southern Ocean'. Not only does the atlas document life in the ocean, it reveals some astonishing surprises. Read more.
Russia claims Australia has territorial motives for Antarctic reserves
Russia has ramped up its attack on proposed Antarctic marine reserves, alleging they hide the territorial ambitions of countries such as Australia. The head of Russia's Arctic and Antarctic Institute, Valery Lukin, lists the marine plans among moves he says polar territorial claimants are making to advance their interests. Read more.
Antarctic coastal waters 'rising faster'
Melting ice is fuelling sea-level rise around the coast of Antarctica, a new report in Nature Geoscience finds. Near-shore waters went up by about 2mm per year more than the general trend for the Southern Ocean as a whole in the period between 1992 and 2011. Read more.
Does Antarctic sea ice growth negate climate change? Scientists say no
In the blue half-light of the Antarctic autumn, a thin film spreads across the continent's coastal waters. It's an embryonic form of sea ice: a mush of microscopic crystals that floats on the dense, salty water of the Southern Ocean. Read more.
What was it like to live on the ice in 1950s?
Three new Antarctic exhibitions will open in Christchurch tomorrow ahead of NZ IceFest arriving in town next month. Read more.
