The Atom and the Ocean

A concise survey explains how nuclear energy and radioactive techniques have been applied to study and exploit the ocean, from powering long‑endurance submersibles and seabed generators to using radioisotope tracers for tracking currents, nutrient cycles, and sediment deposition. It outlines ocean structure and movements, describes instrumentation and research projects, examines the behavior and environmental fate of radionuclides, and reviews engineering applications such as desalination, seafood preservation, and seabed operations. The treatment emphasizes practical uses, safety studies, and the three‑dimensional nature of marine processes.
