Ends of the Earth | Greenpeace International: "This summer, Shell Oil intends to drill five exploratory wells in the Beaufort and Chukchi Seas on Alaska's continental shelf. Although the sea bottom in this region is relatively shallow – 50-meters, compared to a thousand meters or more for deepwater wells – drilling rigs in the Arctic must negotiate moving ice floes, Arctic storms, freezing weather, and 10 weeks of darkness.
Shell admits that they would likely abandon a well capping or spill cleanup during poor Arctic weather. Oil moving under ice floes is out of reach, and the US Geological Survey (USGS) warns that “there is no comprehensive method for cleanup of spilled oil in sea ice.” Furthermore, US Coast Guard Admiral Robert Papp admits that Alaska infrastructure to respond to an oil well blowout, does not exist. Canadian regulators conclude that to drill a blowout relief well in the arctic would take three years."
