The Marshalls provide a crucible for navigation: 70 square miles of land, total, comprising five islands and 29 atolls, rings of coral islets that grew up around the rims of underwater volcanoes millions of years ago and now encircle gentle lagoons. These green dots and doughnuts make up two parallel north-south chains, separated from their nearest neighbors by a hundred miles on average. Swells generated by distant storms near Alaska, Antarctica, California and Indonesia travel thousands of miles to these low-lying spits of sand. When they hit, part of their energy is reflected back out to sea in arcs, like sound waves emanating from a speaker; another part curls around the atoll or island and creates a confused chop in its lee. Wave-piloting is the art of reading — by feel and by sight — these and other patterns. Detecting the minute differences in what, to an untutored eye, looks no more meaningful than a washing-machine cycle allows a ri-meto, a person of the sea in Marshallese, to determine where the nearest solid ground is — and how far off it lies — long before it is visible.Sadly this knowledge is nearly extinct, and you have to wonder how long it will survive in a world of cheap GPS devices.

The Wave Pilots
Fascinating look at how people in the Marshall Islands used to navigate around these remote specks of land by feeling the waves:
