The Arctic is a place of great challenges and great rewards. A century ago, it was whale oil; today, it is motor oil. The increasing open water in the warmer months is attracting cruise ships to tour the Arctic. Significant offshore oil and natural gas deposits are of great interest to an oil-dependent economy. But the history of the Arctic is full of surprises for the unwary and the unprepared, despite native peoples having managed to live there for thousands of years. Oil spills or maritime emergencies can--and do--arise a long way off from assistance. Legendary Arctic storms are, if anything, becoming more intense and dangerous. All this is in an area inaccessible by roads or by sea except for icebreakers the majority of the year. It is of extreme interest to the US Coast Guard, charged with protecting seafarers, enforcing laws, and facilitating commerce.
