A fascinating natural history of an incredibly curious substance. “Preternaturally hardened whale dung” is not the first image that comes to mind when we think of perfume, otherwise a symbol of glamour and allure. But the key ingredient that makes the sophisticated scent linger on the skin is precisely this bizarre digestive by-product—ambergris. Despite being one of the world’s most expensive substances (its value is nearly that of gold and has at times in history been triple it), ambergris is also one of the world’s least known. But with this unusual and highly alluring book, Christopher Kemp promises to change that by uncovering the unique history of ambergris. A rare secretion produced only by sperm whales, which have a fondness for squid but an inability to digest their beaks, ambergris is expelled at sea and floats on ocean currents for years, slowly transforming, before it sometimes washes ashore looking like a nondescript waxy pebble. It can appear almost anywhere but is found so rarely, it might as well appear nowhere. Kemp’s journey begins with an encounter on a New Zealand beach with a giant lump of faux ambergris—determined after much excitement to nothing more exotic than lard—that inspires a comprehensive quest to seek out ambergris and its story. He takes us from the wild, rocky New Zealand coastline to Stewart Island, a remote, windswept island in the southern seas, to Boston and Cape Cod, and back again. Along the way, he tracks down the secretive collectors and traders who populate the clandestine modern-day ambergris trade. Floating Gold is an entertaining and lively history that covers not only these precious gray lumps and those who covet them, but presents a highly informative account of the natural history of whales, squid, ocean ecology, and even a history of the perfume industry. Kemp’s obsessive curiosity is infectious, and eager readers will feel as though they have stumbled upon a precious bounty of this intriguing substance.

A fascinating modern hunt for a treasure from a most surprising source -- a whale's stomach. Journalist and biologist Christopher Kemp discovers, after reading an odd news report, a hidden world of money, intrigue and amazing wealth. A lump of something turns up on a beach in NZ, the lump so strange it may well have come from out of space. But it's not a dead alien, it's ambergris. Ambergris is a by-product of sperm whales, used for centuries as a perfume, medicine and aphrodisiac. It appears on beaches all over the world and depending on what state it's in, can be mistaken for all manner of things. For those in the know, it's an amazing source of wealth - ambergris trades for US$20 a gram, which is nearly as much as gold but it's harder to find and it cannot be mined. Christopher Kemp travels from the shores of NZ, to the Smithsonian and New Nedford Whaling museum; he meets amateurs, professional hunters, scientists, elusive vendors who traffic ambergris, people who won't confess to have found any, and strangers denying what they are looking for. As he discovers more about ambergris' origins, its uses present day and historic, the outrageous lengths people have gone to find it and the intriguing efforts people go to in order to keep what they know about ambergris a secret, the more his infectious obsession grows.

An entertaining and lively history that covers ambergris--a digestive byproduct from whales that is in most perfumes and one of the world's most expensive substances. Kemp presents an informative account of the natural history of whales, squid, ocean ecology, and the perfume industry.
