Nicholas Hoare’s doctoral thesis, Re-Mining Makatea: People, Politics, and Phosphate Rock, provided invaluable background and insights into that singular island. Guy Stevens and Thomas P. Peschak’s Manta: Secret Life of Devil Rays astonished me. Evelyne Beaulieu’s biography draws on the life of Dr. Sylvia Earle, especially as recounted in Sea Change: A Message of the Oceans.
