China's state-of-the-art manned submersible, Jiaolong, dived to a depth of 6,965 metres at the Mariana Trench in the western Pacific and returned safely to the surface late yesterday afternoon with samples of water and sea life.

Exploration ambitions reach new Depths

A manned deep-sea submersible will soon attempt to set a Chinese record for the deepest dive, in a sign of the country's growing prowess in deep-sea exploration as a global race for natural resources intensifies.

Sugar, spice and all things iced

What do 21st-century scientists eat when living and working in places that cannot support human life? Almost anything, as long as it comes with chilli sauce, says Dr Steve Pointing from the School of Biological Sciences at the University of Hong Kong. Pointing's research takes him to some of the most inhospitable places on the planet.

Dreams of a polar pioneer

By the age of 19, British climbers James Hooper and Rob Gauntlett had already conquered Mount Everest, the planet's highest point. But the duo yearned to do something more outrageous - something never attempted before. The adventurers set their hearts on an epic 42,000-kilometre journey from the North Pole to the South Pole, and they would travel only by dogsled, ski, bike and sail.

Student voyages to the icy realms of climate change

For Carol Pun Yik-shan, a 16-day trip to the South Pole in the company of a legendary explorer was the journey of a lifetime.

Saving Antarctica

When Sophie Tang Xiazhen was listening to a talk by British explorer Robert Swan at the University of Hong Kong last year, she knew she would be going to Antarctica.

'I told my boyfriend who was sitting next to me I would be going on the next trip,' Tang says.

The real Antarctic

Joe Wang Hongrui was so excited at seeing penguins, seals and whales up close, he forgot about the seasickness he had suffered on his trip to the Antarctic. But despite the excitement, the trip was not for fun - Wang had headed south early this month to see how global warming has devastated the continent.

Battle for resources

Silent Sound spent the summer sailing through the Northwest Passage, visiting Canadian towns along the way and learning more about Canada's Inuit culture.

Although the shoreline we saw belongs to Canada and the towns we visited were distinctly Canadian, lawyers and politicians are still debating who actually owns the waterway known as the Northwest Passage.

Mission accomplished

We finally made it home! Silent Sound sailed into Halifax Harbour on October 10, completing her four-month journey through the Canadian Arctic. It was cold and raining when we pulled in, but there was still a crowd of family and friends waiting to welcome us ashore.

Sense of achievement

Silent Sound has crossed the Arctic Circle - this means we have completed the Northwest Passage and are leaving the Arctic behind us as we head south and towards home.

We entered the Arctic via the Bering Sea about two months ago, and since then we've seen a lot of ice and learned a lot about the Canadian North. We feel a real sense of accomplishment.

Snow survivors

Earth's frosty poles

Although the Arctic and Antarctic are famous for snow and ice, the two regions are quite different from each other.

The Arctic Ocean lies in the centre of the Arctic Circle, which surrounds the North Pole. The land around it is free from ice most of the year. In summer, the temperature can reach 35 degrees Celsius - just like in Hong Kong.

Race to the Pole is just a rush for fool's black gold

What connects oil at US$135 a barrel with last month's discovery of huge cracks in the Ward Hunt ice shelf off Ellesmere Island at the top of Canada's Arctic archipelago? And what might connect those two things with a new, even colder, war?

Cute reminder of crisis

Reviews of new films & DVDs

Acombination of the messages in Happy Feet, March of the Penguins and An Inconvenient Truth, Arctic Tale may owe its creation to the penguin tales that preceded it. And it is unlikely to have been as successful had An Inconvenient Truth not incited a global campaign for climate change.

An ill wind blows across the Arctic

As global warming melts the ice cap, five nations are in a tug of war to secure ownership of the pristine polar region rich with oil and natural gas resources

While the success of the launch of China's first lunar probe has raised concerns about a new space race, down on Earth another competition has been heating up in the polar area along with global warming.

Conquering the Impossible: My 12,000-mile Journey Around the Arctic Circle

Mike Horn must have a low boredom threshold. Whether any other man pushes himself as hard and risks as much is doubtful.
