The Atomic Bomb Tests in the Marshall Islands by Holly Barker and Jack Niedenthal gives an authoritative account of the testing programme and its consequences for the Marshallese people, written with community input. Niedenthal served for years as a liaison between the Bikinian community and the US government and brings an unusual insider perspective.
Operation Crossroads edited by Jonathan M. Weisgall draws on declassified documents and firsthand accounts to reconstruct the 1946 tests — the events that put the target fleet on the lagoon floor. Weisgall also wrote Operation Crossroads: The Atomic Tests at Bikini Atoll, a more comprehensive single-author treatment.
Nuclear Playground by Stewart Firth examines the wider history of nuclear testing in the Pacific, placing Bikini in the context of French tests in Polynesia and British tests in Australia. Essential for understanding the political dimensions.
For dive preparation, back issues of X-Ray Magazine and Sport Diver contain detailed site guides to the individual wrecks; the Bikini Atoll dive operators maintain updated depth charts and wreck plans that they share with booked guests.
