Governments are deciding whether to create an Antarctic Ocean Sanctuary. What you need to know

If it goes ahead, it’ll be the largest protected area on the planet. The proposed sanctuary is centred on a part of the Antarctic Ocean called the Weddell Sea, which is home to whales, penguins, seals and countless other creatures, some of which we barely understand.

Mt Hope installed as 'UK's highest peak'

Mt Hope, which is sited in the part of the Antarctic claimed by the UK, was recently re-measured and found to tower above the previous title holder, Mt Jackson, by a good 50m (160ft). Hope is now put at 3,239m (10,626ft); Jackson is 3,184m (10,446ft). The map-makers at the British Antarctic Survey (BAS) were prompted to take another look at the mountains because of concerns for the safety of pilots flying across the White Continent.

It is without doubt a remarkable story given the many challenges he and his crew had to overcome after losing their ship, the Endurance. For months they drifted on sea-ice, before making a lifeboat dash to Elephant Island, followed by a hazardous sail across the Southern Ocean to South Georgia.

*****Biosecurity; Invasive species: The latest threat to Antarctica: an insect and plant invasion

Scientists say that as temperatures soar in the polar region, invading plants and insects, including the fly, pose a major conservation threat. More and more of these invaders, in the form of larvae or seeds, are surviving in coastal areas around the south pole, where temperatures have risen by more than 3C over the past three decades. Glaciers have retreated, exposing more land which has been colonised by mosses that have been found to be growing more quickly and thickly than ever before – providing potential homes for invaders.

After all, it has no indigenous inhabitants; only penguins, seals and albatrosses living far away from the dangers faced by wildlife on other continents. Similarly, to political experts, Antarctica is in good hands, governed as it is by the widely celebrated Antarctic Treaty System (ATS), which is considered one of the most successful international legal regimes. But what if I were to tell you that Antarctica is currently the world’s least environmentally protected continent?

Only 1.5% of its ice-free portions have been formally designated as a specially protected area under the ATS, whereas the United Nations Convention on Biological Diversity has recommended a 17% global target. Given that Antarctica has no indigenous people, and that we are told it has no large-scale commercial activity either, the 1.5% figure becomes all the starker.

It may be the only place on Earth where, instead of information on the extent of glaciers or ice caps, there exists a dataset of all non-icy areas compiled from satellite imagery. However, this repository is far from perfect: while satellite resolution and coverage have been steadily improving, Antarctica is challenging ground for remote sensing. 1KM below freezing - @lewispugh swims in 0° C waters to raise awareness about protecting Antarctica's seas. #Antarctica2020 #CleanSeas.

These 5 cities could change the future of the Antarctic

This frozen continent at the bottom of our planet has the potential to either become one of the most fiercely contested zones in the world, or the most collaborative. Antarctica is one of four internationally recognised global commons along with the atmosphere, the high seas and outer space. These are all areas that have historically been guided by the principle of the common heritage of humankind. The continent is governed by the Antarctic Treaty System, a complex set of arrangements developed to regulate relations between states with interests and territorial claims in the region. As of today, 29 states are “consultative parties” to the treaty. Several states have very specific and long-standing interests in Antarctica, which not only determine national policies about engaging with the continent, but can also complicate those engagements.

Antarctic quest to find 'oldest ice' Image copyright BAS/R.Mulvaney Scientists set out this week to try to find the oldest ice in Antarctica. They are seeking a location where they can drill a frozen core that contains a continuous record of climate change stretching back 1.5 million years. The chemistry of this ice can be used to deduce past temperatures on Earth. And tiny bubbles of air trapped inside the core will also betray the levels of heat-trapping gases such as carbon dioxide that were once present in the atmosphere.

This new data is expected to provide additional confidence in the modelled forecasts of how conditions on the planet might develop in the future. "We've got a very good record of what's been happening over the last 800,000 years but there are some aspects which we cannot fully explain," said Dr Robert Mulvaney from the British Antarctic Survey (BAS). The EU-funded Beyond EPICA - Oldest Ice (BE-OI) project will update and extend an effort that was conducted a decade ago. Antarctica, the confusing continent. How much longer can Antarctica’s hostile ocean delay global warming? Colin Monteath/Minden/NGC Strong winds help to pull up ancient water from the ocean bottom. Joellen Russell wasn’t prepared for the 10-metre waves that pounded her research vessel during an expedition south of New Zealand.

“It felt like the ship would be crushed each time we rolled into a mountain of water,” recalls Russell, an ocean modeller at the University of Arizona in Tucson. At one point, she was nearly carried overboard by a rogue wave. But what really startled her was the stream of data from sensors analysing the seawater. Although controversial when she encountered it back in 1994, this powerful upwelling is now recognized as a hallmark of the Southern Ocean, a mysterious beast that swirls around Antarctica, driven by the world’s strongest sustained winds. The hostile conditions have kept oceanographers at bay for decades, but a new era of science is now under way. Tracking carbon.

For decades Antarctica - the only continent with no indigenous population - hosted only the simplest huts as human shelters. But, as Matthew Teller finds out, architecture in the coldest, driest, windiest reaches of our planet is getting snazzier. It's an eye-popping, futuristic design - a dark, sleek building, low and long, that is destined to be a temporary waterfront home for up to 65 people at a time. The price tag is a hefty $100m (£80m).

Today in Ladybird 17 Jan 1912 Scott, Wilson, Oates, Bowers & Edgar Evans reach South Pole, in the knowledge that Amundsen had arrived 1st.

The huge crack in this Antarctic ice shelf just grew by another 6 miles. A Nov. 10 photo made available by NASA shows a view of a massive rift in the Antarctic Peninsula’s Larsen C ice shelf, Antarctica. (John Sonntag/NASA via European Pressphoto Agency) A crack more than 100 miles long in one of Antarctica’s largest ice shelves grew another 6 miles in a little more than two weeks this month, British scientists reported Thursday. That’s on top of an 11-mile growth that occurred in the second two weeks of December — representing a 17-mile total advance in not much more than a month. The extension of the rift in the Larsen C ice shelf ran roughly parallel to the ocean-terminating front of the floating ice shelf, and so, did not bring it any closer to breaking off a large piece — 12 miles of ice still connect the emerging ice island to the larger shelf. But the parallel growth may ensure that the iceberg, when it does break off, will be somewhat larger.
