The Secrets of the Wave Pilots - The New York Times:
"At 0400, three miles above the Pacific seafloor, the searchlight of a power boat swept through a warm June night last year, looking for a second boat, a sailing canoe. The captain of the canoe, Alson Kelen, potentially the world’s last-ever apprentice in the ancient art of wave-piloting, was trying to reach Aur, an atoll in the Marshall Islands, without the aid of a GPS device or any other way-finding instrument. If successful, he would prove that one of the most sophisticated navigational techniques ever developed still existed and, he hoped, inspire efforts to save it from extinction. Monitoring his progress from the power boat were an unlikely trio of Western scientists — an anthropologist, a physicist and an oceanographer — who were hoping his journey might help them explain how wave pilots, in defiance of the dizzying complexities of fluid dynamics, detect direction and proximity to land. More broadly, they wondered if watching him sail, in the context of growing concerns about the neurological effects of navigation-by-smartphone, would yield hints about how our orienteering skills influence our sense of place, our sense of home, even our sense of self"
