This is a review of what is known about fluctuations and anomalous transport processes in tokamaks. It mostly considers experimental results obtained after, and not included in, the reviews of Liewer (Nucl. Fusion {bold 25}, 543 (1985)), Robinson (in {ital Turbulence} {ital and} {ital Anomalous} {ital Transport} {ital in} {ital Magnetized} {ital Plasmas} (Ecole Polytechnique, Palaiseau, France, 1986), p. 21), and Surko (in {ital Turbulence} {ital and} {ital Anomalous} {ital Transport} {ital in} {ital Magnetized} {ital Plasmas} (Ecole Polytechnique, Palaiseau, France, 1986), p. 93). Therefore much of the pioneering work in the field is not covered. Emphasis is placed on results where comparisons between fluctuations and transport properties have been attempted, particularly from the tokamak TEXT (Nucl. Technol./Fusion {bold 1}, 479 (1981)). A brief comparison of experimentally measured total fluxes with the predictions of neoclassical theory demonstrates that transport is often anomalous; fluctuations are thought to be the cause.
