In the high-stakes game of big-wall climbing, the Shark’s Fin on Mount Meru may be the ultimate prize. Sitting at the headwaters of the sacred Ganges River in Northern India, the Shark’s Fin has seen more failed attempts by elite climbing teams over the past 30 years than any other ascent in the Himalayas. To undertake Meru, says Jon Krakauer, the bestselling author of Into Thin Air, "You can’t just be a good ice climber. You can’t just be good at altitude. You can’t just be a good rock climber. It’s defeated so many good climbers and maybe will defeat everybody for all time. Meru isn’t Everest. On Everest you can hire Sherpas to take most of the risks. This is a whole different kind of climbing."
The Southern Ocean, which circles the globe without being blocked by land, is home to the Antarctic Circumpolar Current (ACC), the longest of the world's ocean currents. Also known as the "channel", it connects the Indian, Atlantic and Pacific Ocean basins and exerts a powerful influence over the Earth's climate. The ACC carries 150 times more water around Antarctica than the flow of all the world's rivers combined.
